By utilizing water electrolysis for hydrogen production, carbon neutralization can be advanced technologically and practically. Developing durable, cost-effective electrocatalysts with low overpotentials is essential for electrochemical water splitting. In order to produce hydrogen efficiently, it is important to choose materials that are most suitable for converting energy into hydrogen. Due to their tunable structure, expansive surface area, and outstanding electrocatalytic properties, carbon nanomaterials are becoming increasingly important in this field. Furthermore, their high conductivity and catalytic potential make them promising hydrogen energy candidates. As a precursor material, biochar can be used to produce carbon nanomaterials in an innovative manner. Carbon nanomaterials have been synthesized from biochar in a variety of ways, each producing a different structure. This review discusses biochar production and biochar nanostructures derived from biochar, including carbon dots, carbon tubes, nanofibers, nanosheets, and nanoflakes, along with their energy conversion efficiency and structural tunability. Furthermore, this review investigates recent advances in electrochemical water splitting. It places a particular emphasis on carbon nanomaterials derived from biochar as catalysts. Its objective is to provide valuable insight into the advancement of sustainable hydrogen energy solutions.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e2500093"},"PeriodicalIF":7.5,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145312544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oxygen vacancies, as critical structural defects, significantly enhance the gas sensing performance of MoO3 by modifying its electronic structure and surface chemistry. This review discusses the formation mechanism of oxygen vacancies and their role in improving sensing performance, such as introducing energy levels within the bandgap, altering surface atomic configurations, and promoting gas adsorption and reactions. Experimental and theoretical studies demonstrate that oxygen vacancies enhance sensitivity and selectivity for gases like NH3, NO2, H2S, TEA, and ethanol. Strategies to optimize oxygen vacancy (OV) concentration, including doping with metal/rare earth elements and microstructure design, are also explored. Future research directions include in-depth studies on OV formation mechanisms, performance under complex conditions, and advanced sensor development, supported by theoretical calculations to better understand their effects on MoO3's electronic and adsorption properties.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e202500041"},"PeriodicalIF":7.5,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145291361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of the presence of electron-rich sulfur and nitrogen atoms in its core, phenothiazines are strong electron donors and form charge-transfer salts with many acceptors. Phenothiazines are involved in fast and reversible electron transfer reactions and have been used as photoactive materials in organic light-emitting devices and solar cells. Phenothiazine possesses several active positions on its core where different functional groups have been introduced, and several useful phenothiazine derivatives have been synthesized for various applications. In recent times, attention has been directed toward synthesis of phenothiazine unit(s) as a part of a macrocyclic framework because of their interesting photophysical and redox properties and their potential applications in different fields. Thus, various phenothiazine-embedded macrocyclesa such as calix[n]phenothiazines, phenothiazine-based imine-bridged macrocycles, phenothiazine-based cyclophanes, phenothiazine-based crown ethers, cyclic phenothiaizine arrays, phenothiazine-embedded porphyrinoids, and so on have been synthesized in recent years and exploited their structure and physicochemical properties. In this review, synthesis, structure, and properties of various types of phenothiazine-embedded macrocycles has been described with a hope of stimulating further research on phenothiazine containing macrocycles and their use for a wide range of potential applications.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e2500130"},"PeriodicalIF":7.5,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145257390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although non-noble metals exhibit commendable OER activity, their widespread application is often constrained by stability issues and elevated costs for large-scale deployment. As a result, the focus is shifting from non-noble metals to metal-free catalysts, which offer both abundance and effective catalytic performance. Metal-free catalysts, including carbon-based materials and polymers, typically demonstrate suboptimal catalytic activity in their pure forms. These materials are often doped with other metal-free substances to enhance their performance and modify their electronic structures, increasing the availability of active sites and facilitating improved electron flow for enhanced OER performance. This review examines the latest advancements in the creation of metal-free catalysts for OER and the associated challenges and opportunities within the expanding field of metal-free electrocatalysis. It aims to provide a comprehensive overview of metal-free OER catalysts for researchers entering this dynamic study area.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e202500098"},"PeriodicalIF":7.5,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145243945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
