Notably, ligand-protected Au nanoclusters (NCs) with precisely defined core numbers offer a distinct advantage in elucidating the correlation between their specific structures and the reaction mechanisms in electrocatalysis. The strategic modulation of the fine microstructures of Au NCs presents crucial opportunities for tailoring their electrocatalytic performance across various reactions. This review delves into the profound structural effects of Au NC cores and ligands in electrocatalysis, elucidating their underlying mechanisms. A detailed exploration of the fundamentals of Au NCs, considering core and ligand structures, follows.

Herein, porous carbon nanofibers confined mixed Ni-based crystal phases of Ni2P and NiF2 are developed via fluorination and phosphorization of Ni coated carbon nanofiber (Ni2P/NiF2/PCNF), which possess sufficient mesoporous and optimized Gibbs adsorption free energy by mixed phase-induced charge redistribution. This novel system further reduces the reaction energy barrier and improves the reaction activity by addressing the challenges of low intrinsic activity, difficulty in active site formation, and insufficient synergism. A considerably high current density of 254.29 mA cm−2 is reached at 1.54 V versus reversible hydrogen electrode on a glass carbon electrode, and the cell voltage requires 1.39 V to get 10 mA cm−2 in hydrogen generation, with very good stability, about 190 mV less than that of the traditional water electrolysis. The facile active phase formation and high charge transfer ability induced by asymmetric charge redistribution are found in the interface, where the urea molecules tend to bond with Ni atoms on the surface of heterojunction, and the rate-determining step is changed from CO2 desorption to the fourth H-atom deprotonation.

Herein, carbon nanofiber-supported V2O3 with enriched oxygen vacancies (OV-V2O3@CNF) was fabricated using the facile electrospinning method, followed by thermal reduction. Differing from the traditional particles embedded within carbon nanofibers or irregularly distributed between carbon nanofibers, the free-standing OV-V2O3@CNF allows for V2O3 nanosheets to grow vertically on one-dimensional (1D) carbon nanofibers, enabling abundant active sites, shortened ion diffusion pathway, continuous electron transport, and robust structural stability.

One such material is WT char, which has properties comparable to those of carbon materials used as an active electrode material in batteries.

With the continuous exploitation of solar hydrogen evolution, the performance of photo(electro)catalysts has been greatly optimized. However, the solar-driven hydrogen production for most semiconductors, especially for organic semiconductors, is limited due to the lack of active centers and serious electron–hole recombination. Recently, it has been reported that carbon-carbon triple bonds (C≡C) can function as active sites for hydrogen evolution, and diacetylenic moiety in organic semiconductors is able to increase carrier migration as well. Therefore, organic semiconductors containing C≡C have attracted considerable attention in the past few years. In this review, organic materials or organic–inorganic hybrids containing C≡C for photo(electro)catalytic solar hydrogen production are classified first, including graphdiyne, conjugated acetylene polymers, some covalent organic frameworks, and metal–organic frameworks. After that, the structure, properties, and advantages and disadvantages of C≡C-containing materials are introduced and summarized. Apart from these, this review also presents advances in materials containing C≡C in the field of solar hydrogen generation. Finally, perspectives on the future development of C≡C-containing materials in the field of solar hydrogen generation are also briefly anticipated. This review provides pertinent insights into the main challenges and potential advances in the organic semiconductors for solar-driven hydrogen production, which will also greatly contribute to other photo(electro)catalytic reactions.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"6 11","pages":""},"PeriodicalIF":19.5,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.527","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141375313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its cyclability is still a major problem in terms of commercial applications. Herein, we propose a simple but effective method to greatly improve the high-voltage cyclability of an LCO cathode by constructing a surface LiF modification layer via pyrolysis of the lithiated polyvinylidene fluoride (Li-PVDF) coating under air atmosphere. Benefitting from the good film-forming and strong adhesion ability of Li-PVDF, the thus-obtained LiF layer is uniform, dense, and conformal; therefore, it is capable of acting as a barrier layer to effectively protect the LCO surface from direct exposure to the electrolyte, thus suppressing the interfacial side reactions and surface structure deterioration. Consequently, the high-voltage stability of the LCO electrode is significantly enhanced. Under a high charge cutoff voltage of 4.6 V, the LiF-modified LCO (LiF@LCO) cathode demonstrates a high capacity of 201 mA h g−1 at 0.1 C and a stable cycling performance at 0.5 C with 80.5% capacity retention after 700 cycles, outperforming the vast majority of high-voltage LCO cathodes reported so far.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"6 10","pages":""},"PeriodicalIF":19.5,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.602","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141382728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
