Abstract

: Biochar has garnered considerable attention in recent times due to its potential uses in the environmental field. In this study, we comprehensively examine and condense information on biochar production, characteristics, and adsorption mechanisms, with a focus on its economic applications for remediating hazardous contaminants. Our assessment is based on over 200 publications from the past decade. Biochar, a carbon-rich material, can be derived from various organic waste sources, such as food waste and urban sewage sludge. Researchers are particularly interested in biochar due to its high carbon content, cation exchange capacity, substantial specific surface area, and stable structure. We investigate how the physical and chemical properties of biochar may vary based on the feedstock used, providing a comprehensive overview of biochar and its composition for pollution remediation. The review also discusses common techniques such as gasification, hydrothermal carbonization, and pyrolysis used to produce biochar. We analyze current research on the mechanisms involved in pollutant treatment using biochar and its composites while also addressing future directions in biochar research.

生物炭及其复合材料在修复有害污染物方面的最新进展

:近年来，生物炭因其在环境领域的潜在用途而备受关注。在本研究中，我们全面研究并浓缩了有关生物炭的生产、特性和吸附机制的信息，重点关注其在修复有害污染物方面的经济应用。我们的评估基于过去十年间发表的 200 多篇论文。生物炭是一种富碳材料，可从食物垃圾和城市污水污泥等各种有机废物中提取。由于生物炭具有高碳含量、阳离子交换能力、巨大的比表面积和稳定的结构，研究人员对生物炭特别感兴趣。我们研究了生物炭的物理和化学性质如何根据所使用的原料而变化，全面概述了用于污染修复的生物炭及其成分。综述还讨论了用于生产生物炭的气化、热液碳化和热解等常见技术。我们分析了当前利用生物炭及其复合材料处理污染物的机制研究，同时还探讨了生物炭研究的未来方向。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
