Manganese oxides, particularly Mn3O4, stand out as promising cathode materials due to their electrochemical virtues and affordability. However, traditional synthesis methods like solid-state reactions, hydrothermal processes, and sol–gel techniques often entail complex procedures, high temperatures, and environmentally harmful chemicals, which impede their practical applications. This study introduces a novel, eco-friendly synthesis route for Mn3O4 nanoparticles via the room-temperature reaction of morpholine with manganese nitrate for 24 h, reducing both the environmental impact and the complexity of production. This method yields Mn3O4 nanoparticles with enhanced crystallinity and surface area, which is crucial for improved electrochemical performance in ZIBs by offering increased active sites for zinc intercalation. The resultant high-performance Mn3O4 nanoparticles align with sustainable practices and hold the potential for advancing next-generation energy storage technologies. The detailed structure and electrochemical performance were investigated in detail in this study. The produced Zn//Mn3O4 nanoparticles cell exhibited a remarkable electrochemical performance, which displayed a high reversible capacity of 209.7 mAh g−1 after 300 cycles at 0.6 A g−1.","PeriodicalId":72913,"journal":{"name":"Energy advances","volume":" 12","pages":" 2903-2909"},"PeriodicalIF":3.2,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/ya/d4ya00539b?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142778046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we established an efficient method for selective production of H2 gas and lactic acid (LA) from aqueous glycerol under mild reaction conditions (90–130 °C) over various supported ruthenium catalysts. Notably, we achieved a substantial yield of H2 gas (n(H2)/n(GLY) ratio of 1.4 with >99.9% H2 purity) and LA (86%) from glycerol over Ru nanoparticles immobilized over a La(OH)3 support (Ru/La(OH)3) in contrast to bare Ru nanoparticles where we observed a n(H2)/n(GLY) ratio of 1.6 with only 70% yield of LA as we reported previously. We could significantly boost the generation of both H2 gas and LA by tuning the reaction parameters, including reaction time, temperature, base, and water concentrations. Furthermore, the effect of various support materials such as Mg(OH)2, ZnO, ZrO2, and TiO2 was also tested for H2 production from GLY under optimized reaction conditions. The employment of various characterization techniques to understand the physicochemical properties of the synthesized supported Ru catalysts revealed that the choice of support material significantly influenced the catalytic activity towards the selective production of H2 and LA.","PeriodicalId":72913,"journal":{"name":"Energy advances","volume":" 1","pages":" 106-118"},"PeriodicalIF":3.2,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ya/d4ya00213j?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, SEI formation and electrolyte decomposition are examined with linear potential scans, where time and potential dependencies are intertwined. Herein, a stepwise potential variation in combination with amperometry and electrochemical impedance spectroscopy (EIS) is used to characterize the impacts of time and potential as individual degrees of freedom on the SEI formation. Based on EIS data, the double layer capacitance (DLC) is introduced as a sensitive in situ metric to monitor the SEI formation. This technique is used to show the similarities and differences in the SEI formation processes with typical Li–ion battery electrolytes consisting of hexafluorophosphate and carbonate solvents. A polished glassy carbon electrode is employed to provide model-like EIS data with reliable interpretation. Changes in the electrochemical interface within only few atomic layers are tracked with DLC, indicating that SEIs are formed below 1.9 V vs. Li/Li+ with the employed electrolytes. Amperometry measurements show that the decomposition of the employed electrolytes starts at approximately 2.7 V vs. Li/Li+, displaying smaller electrochemical windows than those previously reported.","PeriodicalId":72913,"journal":{"name":"Energy advances","volume":" 1","pages":" 140-151"},"PeriodicalIF":3.2,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ya/d4ya00524d?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The LEDs rely on the charge carrier diffusion induced light emitting diode concept. The GaInP core has a higher Ga content than the branches to induce diffusion of carriers from the cores into the branches. The branches play the role of the active region in the structure, where charge carriers recombine to emit light. We investigate the impact of n-doping the branches on the performance of the LEDs. Electroluminescence measurements provide insights on the emission spectrum with varying dopant molar fraction. External quantum efficiency (EQE) measurements provide insights into the device quality, and reveal the limitations encountered in processing, such as the high sheet resistance of the indium tin oxide (ITO) transparent conductive top contact.

This study introduces two analogues of the biological redox co-factor flavin (BFG, BFA) as bioinspired electron-transporting materials featuring solubilizing ethylene glycol and alkyl side chains. These materials demonstrated a conductivity of ∼5.6 × 10−7 S cm−1 in their pristine form which compares favourably with widely employed PCBM (6.8 × 10−8 S cm−1). To enhance the conductivity of the material the chemical dopant N-DMBI was added. UV-vis absorption and electron spin resonance measurements confirmed radical anion formation, while glycol-functionalized derivative BFG shows faster reactivity toward the dopant due to increased polarity of the acceptor molecule conferred by the more polar side chain. Surprisingly, these materials did not exhibit the expected enhancement effect in terms of conductivity or increased power conversion efficiency in perovskite solar cells. DFT calculations correlated to features in the absorption spectra of the compounds indicates the formation of stable charge-transfer complexes upon the addition of the dopant. We hypothesise that this inhibits electron transfer of the reduced species in the film to its undoped neighbour and thereby prevents effective doping. Our results highlight the significance of charge-transfer complexation in the design of future electron transporting materials for perovskite solar cells and advocates the use of low cost DFT modelling early on in the design of these species and their dopants.","PeriodicalId":72913,"journal":{"name":"Energy advances","volume":" 12","pages":" 2939-2946"},"PeriodicalIF":3.2,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/ya/d4ya00369a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142778029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, aqueous zinc–iron redox flow batteries have received great interest due to their eco-friendliness, cost-effectiveness, non-toxicity, and abundance. However, the development of zinc–iron redox flow batteries (RFBs) remains challenging due to severe inherent difficulties such as zinc dendrites, iron(III) hydrolysis, ion-crossover, hydrogen evolution reactions (HER), and expensive membranes which hinder commercialization. Many scientific initiatives have been commenced in the past few years to address these primary difficulties, paving the way for high-performance zinc–iron (Zn–Fe) RFBs. This review collectively presents the various aspects of the Zn–Fe RFB including the basic electrochemical cell chemistry of the anolyte and catholyte, and the different approaches considered for electrodes, electrolytes, membranes, and other cell components to overcome the above issues.

Several efforts have been made to boost the HER performance by tagging a co-catalyst. But no such significant approach was developed to improve the HER activity of pristine MAPbI3. In this work, the shape and morphology of MAPbI3 have been modified by a simple solvent change route. This led to substantial transformation in shape and morphology affecting various facets of photocatalytic and photoelectrochemical performance. DMF assisted pristine MAPbI3 exhibited an HER activity of 830 μmol h−1 g−1, almost 28-fold better than that of typical HI based MAPbI3. This work highlights how solvent transition from HI to DMF can influence the shape and surface morphologies which impact the photocatalytic and photoelectrochemical performances of pristine MAPbI3. To further enhance the HER activity of DMF assisted MAPbI3, the as-synthesized polyfluorene co-catalyst was integrated on the MAPbI3 surface.
