The Bi4O5Br2/g-C3N4 composite with a heterojunction structure exhibited high adsorption and photocatalytic activity for removal of tetracycline (TC) and ciprofloxacin (CIP) with excellent cyclic stability, owing to its large specific surface area as well as enhanced charge separation and visible light utilization.

This review starts from the developmental history of the MIA strategy and then discuss general protocols to fabricate the monomicelles. After that, manipulation of the monomicelles' assembly by well-designed interfaces and confined spaces for the controllable fabrication of LDMNs are reviewed in detail. Then, catalytic applications, including thermal, photo- and electrocatalysis, of LDMNs are discussed critically based on the structure-performance relationship.

Photoelectrochemical (PEC) water splitting, which directly converts sunlight into hydrogen fuel, offers a promising renewable energy technology. Semiconductors, used as photoelectrodes, provide the most feasible method for converting solar energy into electrical energy and chemical fuels. Unfortunately, most of the common semiconductors used in PEC water splitting have wide bandgaps, which greatly restrict the utilization efficiency of sunlight. To promote the solar-to-hydrogen (STH) efficiency of PEC water splitting, atomically precise clusters with regular crystal structures have been introduced in the PEC systems. In this review, the recent advances in nanoclusters for PEC water splitting, including metal clusters, polyoxometalates, semiconductor clusters, and carbon clusters, are summarized. At last, major challenges and outlook for the development of clusters for PEC water splitting are provided.","PeriodicalId":100387,"journal":{"name":"EcoEnergy","volume":"1 1","pages":"60-84"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ece2.6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136069726","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 design and construction of highly active catalysts with affordable prices toward alkaline hydrogen evolution reaction (HER) are effective in accelerating the overall water-splitting process. So far, ruthenium (Ru) based catalysts deliver comparable or even superior catalytic performance relative to the platinum (Pt)/C benchmark. Combined with their price advantage, Ru-based catalysts are undoubtedly considered as one of the perfect alternatives of Pt toward the alkaline HER. Extensive efforts have been made to reasonably synthesize Ru-related materials, but a careful insight into material engineering strategies and induced effects remain in its infancy. In this review, recent progress on the material engineering strategies for improving the catalytic activity of Ru-related catalysts, including electronic regulation, geometric modulation, local structure alteration, self-optimization strategies, and the induced structure–activity relationship are comprehensively summarized. Furthermore, the challenges and perspectives on future studies of Ru-related electrocatalysts for the alkaline HER are also proposed.","PeriodicalId":100387,"journal":{"name":"EcoEnergy","volume":"1 1","pages":"16-44"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ece2.4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136359371","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}

However, developing cost-effective electrocatalysts with high NRR efficiency at low overpotential in neutral media remains a great challenge. In this paper, a freestanding NRR electrocatalyst, BiFeO/FCC, has been developed by in situ growth of bismuth ferrite (Bi25FeO40) on functionalized carbon cloth (FCC), which exhibits high NRR activity with a maximum NH3 yield of 3.88 μg h−1 cm−2 (at −0.40 V vs. reversible hydrogen electrode [RHE]) and a Faradaic efficiency of 12.71% (at −0.45 V vs. RHE) in 0.1 M Na2SO4. The synergistic effect of the abundant exposed bismuth and iron dual active sites confined in the lattice, the binder-free nature of the electrode and the excellent conductivity of the carbon substrate enable the easy adsorption/activation of N2 and accelerate the electron transfer simultaneously, thus boosting its NRR performance. This work is significant to design low-cost, and high-efficient NRR catalysts for large-scale electrocatalytic NH3 synthesis.","PeriodicalId":100387,"journal":{"name":"EcoEnergy","volume":"1 1","pages":"186-196"},"PeriodicalIF":0.0,"publicationDate":"2023-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ece2.3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135207932","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}
