To understand which factors induce charge recombination, we studied electrodes with a varying number of NiO layers in benchmark P1 p-DSSCs. We obtained the most efficient DSSCs with four layers of NiO (0.134%), and further insights into this optimum were obtained via dye loading studies and in operando photoelectrochemical immittance spectroscopy. These results revealed that more NiO layers led to an increasing light harvesting efficiency (ηLH), but a decreasing hole collection efficiency (ηCC), giving rise to the maximum efficiency at four NiO layers. The decreasing ηCC with more NiO layers is caused by longer hole collection times, which ultimately limits the overall efficiency. Notably, the recombination rates were independent of the number of NiO layers, and similar to those observed in the more efficient n-type DSSC analogues, but hole collection was an order of magnitude slower. Therefore, with more NiO layers, the beneficial increase in ηLH can no longer counteract the decrease in ηCC due to slow hole collection, resulting in the overall efficiency of the solar cells to maximize at four NiO layers.","PeriodicalId":72913,"journal":{"name":"Energy advances","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/ya/d4ya00271g?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141512403","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}

Cobalt oxide is one of the promising materials for oxygen evolution reaction (OER). Modifying the metal oxide by the incorporation of metal ions and substituting sulfides are effective but challenging strategies for achieving efficient OER activities. In the present work, we report the synthesis of CdCoO and CdCoS electrocatalysts deposited on the surface of nickel foam. These electrocatalysts and their composites CdCoO@CuCoO and CdCoS@CuCoS could deliver high catalytic activity for oxygen evolution reaction. The as-synthesized electrocatalysts were characterized using pXRD, FTIR spectroscopy, Raman spectroscopy, XPS, and SEM techniques. The CdCoS showed a lower OER overpotential of 199 mV at a current density of 10 mA cm−2 and 522 mV at 60 mA cm−2. The incorporation of Cd2+ ions in the cobalt oxides optimized the electronic states around the Co active sites, leading to improved catalytic activities and a lower overpotential compared to other reported cobalt oxides (such as oxyhydroxides). This work emphasizes the effect of metal-ion incorporation and sulfide modification on the OER activity of cobalt oxide for water splitting and provides a multicomponent engineering strategy for designing efficient electrocatalysts.","PeriodicalId":72913,"journal":{"name":"Energy advances","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/ya/d4ya00327f?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141530381","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}

In this regard, investigation of their stability and possible degradation mechanism in the presence of moisture is of utmost necessity. A detailed analysis with the help of ab initio molecular dynamics simulations has been carried out to understand their interaction with water interfaces for the first time. Various possible terminations of Ruddlesden–Popper (RP) and Dion–Jacobson (DJ) phases of 2D hybrid perovskites have been considered. We monitor the various possible interactions in the perovskite/water interface model to reveal the robustness of various terminations. PbI2 terminated structures are found to interact mainly through Pb–O interactions, and the DJ phase is found to be more robust. I2 formation is found to be the possible degradation route for I terminated phases. The importance of the bulky hydrophobic organic cation layer is highlighted, whose unique arrangement plays an essential role in resisting water infiltration and dissolution of surface components in the case of organic cation terminated phases. Interestingly, the organic cation layer is found to be robust in 2D hybrid perovskites compared to reported 3D perovskites. Our study signifies the opportunity to tune the cation layer, thereby maintaining moisture stability without compromising the optoelectronic properties of 2D hybrid perovskites, thus contributing to the fundamental understanding of 2D hybrid perovskites at water interfaces.","PeriodicalId":72913,"journal":{"name":"Energy advances","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/ya/d4ya00235k?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141507491","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}

Development of advanced, high-capacity anodes is essential for enhancing their performance, safety, and durability, and recently, two-dimensional materials have garnered extensive attention in this regard due to distinct properties, particularly their ability to modulate van der Waals gap through intercalation. Covalently intercalated Graphene oxide interlayer galleries with mono-Boc-ethylenediamine (GO-EnBoc) was synthesized via the ring opening of epoxide, forming an amino alcohol moiety. This creates three coordination sites for Li ion exchange on the graphene oxide nanosheets' surface. Consequently, the interlayer d-spacing expands from 8.47 Å to 13.17 Å, as anticipated. When explored as an anode, Li–GO–EnBoc shows a significant enhancement in the stable and reversible capacity of 270 mA h g−1 at a current density of 25 mA g−1 compared to GO (80 mA h g−1), without compromising the mechanical or chemical stability. Through 13C, 7Li and 6Li MAS NMR, XPS, IR, Raman microscopy, and density functional theory (DFT) calculations, we confirm the positioning of Li+ ions at multiple sites of the interlayer gallery, which enhances the electrochemical performance. Our findings suggest that these novel systematically modulated van der Waals gap GO-engineered materials hold promise as efficient anodes for Li-ion batteries.","PeriodicalId":72913,"journal":{"name":"Energy advances","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/ya/d4ya00217b?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141529714","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}

This study investigated two-electrode PSC systems based on three-dimensional (3D) zinc oxide (ZnO) nanoflakes/reduced graphene oxide (rGO) nanocomposites to meet the need for in situ solar energy conversion/storage. To better understand the effect of rGO and 3D ZnO nanoflakes separately, three different compositions have been studied, in which the weight percent of rGO changes from 8 to 32%. The energy density increases as the amount of rGO increases, but the composite material loses its light sensitivity above a critical value. Therefore, the electrodes containing 16% rGO exhibited higher performance than those containing 32% and 8% rGO.

In this work, we developed a framework to estimate the national SAF potential and applied it to a case study for canola SAF in Canada. Specifically, we answered (i) how many SAF plants can be constructed and what are their maximum name-plate capacities? (ii) which geographic locations can economically support a SAF plant? (iii) what could be the average life cycle GHG emissions of SAF supplied to major airports? Our study developed an improved framework for estimating the SAF potential for a region by incorporating detailed site selection criteria for identifying optimal locations. We found that 15.2 million metric tonnes (MT) of potentially available canola can supply about 1–1.8 billion litres of SAF by 2030 (12–21% of Canada's 2019 jet fuel consumption) across 7–11 optimal sites, after accounting for infrastructure and accepted industry/financing guidelines on feedstock utilization. Up to 20% of this potential is lost if there is a lack of coordination and plants are sited sequentially based on profitability instead of maximizing feedstock utilization. The life cycle-GHG emissions of the SAF produced in the optimal sites ranged between 20–58 g CO2e per MJ, depending on the local farming practices and legacy land use & land management changes. Increasing the supply chain transportation connectivity and managing feedstock competition could provide access to more canola for SAF production; however, other pathways will also be required to meet the growing SAF demand in Canada.","PeriodicalId":72913,"journal":{"name":"Energy advances","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/ya/d3ya00579h?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141507492","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}
