Suitable TE materials should have high power factors (PFs) and low thermal conductivities, where PF = S2σ, with S being the Seebeck coefficient and σ the electrical conductivity. Most recent improvements in TE materials have been achieved by the reduction of the thermal conductivity, and strategies to improve the PF have been minor. Recently, our group reported a new concept to significantly increase the PF, based on the combination of a porous TE solid with an electrolyte. Herein, we made use of this new approach but using polyelectrolytes, rather than the liquid electrolytes previously employed. Poly(diallyldimethylammonium X) polyelectrolytes were tested, where X = Cl− (C) or tosylate (Tos). An average PF improvement of 2.6 times was obtained when PDADMAC was used, similar to the enhancement with liquid electrolytes. This was due to average decreases of 13% and 71% in the absolute value of the Seebeck coefficient and the electrical resistance of the system, respectively. An electrochemical study by impedance spectroscopy and cyclic voltammetry revealed the better capability of PDADMAC to screen the charge introduced in the oxide compared with that of PDADMATos. The resistance reduction for PDADMAC was attributed to variations in the carrier concentration in the oxide after its equilibration with the polyelectrolyte. The notable PF improvement obtained paves the way for the use of polyelectrolytes to fabricate all-solid-state solid-electrolyte systems with enhanced PFs.","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 5","pages":" 1217-1224"},"PeriodicalIF":5.0,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/se/d4se01471e?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a main component derived from biomass, acetic acid (HAc) shows potential in green hydrogen production via auto-thermal reforming (ATR) of HAc. In the ATR process, although Ni-based catalysts exhibited high activity for the conversion of HAc, issues of oxidation, sintering and coking remain to be addressed. Therefore, nickel-based catalysts loaded on the Sm6WO12 tungstate structure were fabricated by the co-precipitation method, and the structure–reactivity relationship was explored. The characterization results showed that a stable Sm6WO12 tungstate structure was formed after the introduction of W species in Sm oxides, promoting reduction and dispersion of Ni on the catalyst surface with a high Ni0/(Ni0 + Ni2+) ratio of NSW20 at 40.8%. Meanwhile, abundant oxygen vacancies were formed in the tungstate structure, which accelerated the conversion of reactants H2O and O2 into active oxygen species (O*), and enhanced the oxidation of coking precursors (C*), thereby efficiently inhibiting coking of the catalyst. As a result, the NSW20 catalyst with a Sm6WO12 support exhibited high catalytic activity in the ATR process: the conversion of HAc was stable at 100.0%, and the yield of hydrogen was maintained near 2.42 mol-H2 per mol-HAc, while the apparent activation energy (Ea) and turnover frequency (TOF-H2) were recorded to be 43.5 kJ mol−1 and 2.38 × 10−2 s−1, respectively.","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 5","pages":" 1268-1278"},"PeriodicalIF":5.0,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This would require about 89 million tonnes (Mt) of glass yearly, yet the actual production output of solar glass is only 24 Mt, highlighting a significant supply shortfall (3.7 times). Moreover, there is scarce information about the iron content of many sand deposits worldwide. Low-iron sand is required for PV glass production, to make the glass highly transparent and reduce the absorption of solar energy. Additionally, glass manufacturing leads to significant emissions, with fossil fuels being the primary energy source. Recycling offers a promising partial solution, with some available techniques enabling the clean recovery and reuse of end-of-life PV glass (cullet) for new panels. Similarly, methods such as the Hot Knife and Delam processes could recover entire glass cover sheets for potential reuse in new PV modules. Furthermore, there is an opportunity to establish new glass factories with lower emissions through strategies such as hydrogen fuel adoption, electrification, and waste heat recovery.","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 6","pages":" 1414-1431"},"PeriodicalIF":5.0,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/se/d4se01567c?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The heterogeneous polymer–polymer and polymer–GMH interactions in these hybrid nanocomposites (HNCs), as well as the composition-dependent crystal phases of the PVDF, were validated by the structural and morphological characteristics.

Drift-diffusion simulations and experimental C–V measurements were employed to analyse devices incorporating Spiro-OMeTAD and CuSCN as HTLs. The simulations revealed that ionic charge accumulation predominantly at the perovskite/HTL interface affects the internal electric field distribution, with mobile cation density playing a crucial role in screening the built-in electric field within the perovskite layer. The density of mobile cations in the perovskite can increase by the diffusion of Li+ and Co3+ ions from the Spiro-OMeTAD layer, resulting in a more steep and narrow doping profile compared to the CuSCN-based device. Simulations and experiments demonstrate that mobile ions, despite not directly responding to the high-frequency AC signals used in C–V characterisation, influence capacitance by affecting electronic carrier distribution. Analysis of doping profiles reveals that bias-modulated ionic accumulation at interfaces contributes to both U-shaped and distinct W-shaped doping profiles observed in Spiro-OMeTAD devices. Devices with Spiro-OMeTAD exhibited higher capacitance and more pronounced hysteresis due to intensified charge accumulation, while CuSCN-based devices displayed a faster capacitance response and reduced hysteresis, attributed to a more uniform charge distribution. Despite the increased hysteresis in Spiro-OMeTAD devices, they achieved higher power conversion efficiencies (PCE), highlighting a complex relationship between hysteresis and performance and emphasising the importance of HTL selection and ion management for PSC optimisation.","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 5","pages":" 1225-1235"},"PeriodicalIF":5.0,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite a H2 storage capacity of 10.3 wt%, pristine aza-COF adsorbs H2 molecules via weak van der Waals interactions, limiting its viability under ambient conditions. The strategy relies on increasing more active sites for H2 adsorption, thereby improving the interactions between H2 and positively charged Li atoms.

This study introduces a low-temperature etching-assisted synthesis approach to fabricate iron-doped nickel hydroxide (Fe–Ni(OH)2) bifunctional electrocatalysts for overall water splitting. The catalysts synthesized using this low-temperature method tend to form a composite structure consisting of nanosheets and nanoflowers, along with a mixed phase of crystalline and amorphous materials. This unique combination significantly enhances electron transport and increases the number of active sites. Furthermore, iron doping promotes the formation of high-valent nickel species, resulting in the coexistence of NiFe bimetallic hydroxides (Ni(Fe)LDH) and NiFe oxyhydroxides (Ni(Fe)OOH) within the catalyst. This coexistence ensures exceptional performance in both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) under alkaline conditions. Notably, the overpotentials for the HER and OER at a current density of 10 mA cm−2 in a 1.0 M KOH solution are as low as 92 mV and 232 mV, respectively. Moreover, the Fe–Ni(OH)2/NF catalyst demonstrates superior overall water splitting performance, achieving a cell voltage of just 1.59 V at a current density of 10 mA cm−2.

According to the Shockley–Queisser limit, single-junction PSCs are predicted to achieve a maximum efficiency of ≈33%. However, open circuit voltage (VOC) losses originating from non-radiative recombination at the absorber/charge transporting layer (CTL) interfaces due to band-level mismatches and defect states cause a lag in achieving the actual limit of PSCs. Composition-dependent bandgap tuning in halide perovskites offers a great advantage in tuning the optical properties of the absorber layer. In this article, we introduce a novel scheme for absorber band grading by altering the metallic or B-site composition of the FAPb1−ySnyI3 perovskite absorber. By replacing the single absorber layer (FAPb0.5Sn0.5I3) in the device configuration ITO/PEDOT:PSS/FAPb0.5Sn0.5I3/PCBM/Ag using a graded bandgap absorber (FAPb1−ySnyI3) with y varying between 0 and 1, a full range grading, the efficiency limit of the device is extended by 95%. Besides, a more convenient partial grading scheme with y of a smaller range can yield satisfactory results. A systematic study of both these grading schemes and simulations reveals that such an architectural design strategy with precise execution could be the next step in overcoming the practical limits of conventional single absorber PSCs.","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 5","pages":" 1305-1316"},"PeriodicalIF":5.0,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
