摘要

近年来,通过热解废弃生物质制备环保富碳(生物炭)材料已被公认为是最经济、最有效的气体净化策略之一。通过控制合成和活化方法,生物炭的表面特征和催化位点可被设计用于多种异相催化反应。然而,由于 (i) 缺乏与生物炭实际催化性能相关的数据库;(ii) 工业升级的复杂性,生物炭在空气污染控制中的商业利用在很大程度上受到限制。本文讨论了生物质转化为生物炭催化剂的优缺点,以及在合成阶段为提高空气净化应用催化活性而应考虑的因素。本文还对基于生物炭的催化剂及其用于空气污染控制和能源生产的催化反应的技术经济和环境方面进行了深入评估。最后,本文提出了一个现代视角,以帮助开发新型生物炭基催化剂,用于空气净化领域的实际应用。

Recent Advances in Biochar-based Catalysts: Air Purification and Opportunities for Industrial Upscaling

The preparation of eco-friendly carbon-rich (biochar) materials by thermal pyrolysis of waste biomass has been recognized as one of the most economical and effective strategies for gas purification in recent years. Through control of synthesis and activation methods, the surface features and catalytic sites in biochar can be engineered for diverse heterogeneous catalytic reactions. Nonetheless, its commercial utilization in air pollution control has yet been limited to a large extent because of (i) the shortage of databases related to the actual catalytic performance of biochar and (ii) the complexity involved in industrial upscaling. Herein, the merits and demerits of biomass-to-biochar catalyst conversion are discussed, along with the factors to consider in the synthesis stage for enhancing catalytic activities toward air purification applications. This paper also offers an in-depth evaluation of the techno-economic and environmental aspects of biochar-based catalysts and their catalytic reactions for air pollution control and energy production. Lastly, a contemporary perspective is offered to help develop novel biochar-based catalysts for real-world applications in air purification fields.
