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. Meanwhile, density functional theory calculations confirmed that the oxygen vacancies can promote intrinsic electron conductivity and reduce ion diffusion energy barrier. Consequently, the OV-V2O3@CNF anode delivers a large reversible capacity of 812 mAh g−1 at 0.1 A g−1, superior rate capability (405 mAh g−1 at 5 A g−1), and long cycle life (378 mAh g−1 at 5 A g−1 after 1000 cycles). Moreover, an all-vanadium full battery (V2O5//OV-V2O3@CNF) was assembled using an OV-V2O3@CNF anode and a V2O5 cathode, which outputs a working voltage of 2.5 V with high energy density and power density, suggesting promising practical application. This work offers fresh perspectives on constructing hierarchical 1D nanofiber electrodes by combining defect engineering and electrospinning technology.","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"6 9","pages":""},"PeriodicalIF":19.5,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.517","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141374045","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}

One such material is WT char, which has properties comparable to those of carbon materials used as an active electrode material in batteries. Therefore, a systematic review of the various thermochemical approaches used to convert WTs into carbon materials for electrode applications was conducted. The review shows that pretreatment processes, various process routes, and operating parameters affect derived carbon properties and its respective electrochemical performance. WT-derived carbon has the potential to yield a high specific capacity greater than the traditional graphite (372 mAh g−1) commonly used in lithium-ion 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}

The increased compressibility of roasted wood intensifies the deformation of cellulose microfibrils, significantly enhancing the piezoelectric effect in wood. Roasted wood (15 × 15 × 15 mm3, longitudinal × radial × tangential) can generate a voltage and current outputs of 1.4 V and 14.5 nA, respectively, which are more than 70 times that of natural wood. The wood sample can recover 90% of its shape after 5000 compressions at 65% strain, exhibiting excellent elasticity and stability. Importantly, roasted wood does not add any toxic substances and can be safely applied on the human skin as a self-powered sensor for detecting body movements. Moreover, it can also be assembled into self-powered wooden floors for energy harvesting.

In recent years, extensive theoretical and experimental studies have demonstrated that cobalt (Co)-based nanomaterials, especially low-dimensional Co-based nanomaterials with a huge specific surface area and abundant unsaturated active sites, have emerged as versatile electrocatalysts for oxygen evolution reactions, and thus, great progress has been made in the rational design and synthesis of Co-based nanomaterials for electrocatalytic oxygen evolution reactions.
