生物炭改性在催化应用上的研究

Study on catalytic application of biochar modification

生物炭是从生物质中热解得到的一种中性富碳材料。它不仅是一种环境友好的吸附降解改良手段,还给碳捕获和碳储存提供了一种可行思路。重点介绍了生物炭的几种常用的改性方法,总结了其在有机无机污染物去除,多相催化,光催化和微生物燃料电池电极等方面的催化应用以及作用机制,提出了生物炭及其改性材料在催化挑战和实践中的困难,展望了未来的研究方向。

Biochar is a neutral carbon-rich material obtained from pyrolysis of biomass.It is not only an environmentally friendly improved means of adsorption and degradation,but also provides a feasible idea for carbon capture and storage.This review focuses on several commonly used modification methods of biochar,summarizes its catalytic applications and action mechanisms in the removal of organic and inorganic pollutants,multiphase catalysis,photocatalysis and microbial fuel cell electrodes,puts forward the challenges and practical difficulties of biochar and its modified materials in catalysis,and looks forward to the future research direction.
