Abstract

Metals are widely used in the field of catalysis because of their high activity and selectivity. In recent years, the deactivation and poisoning of metal catalysts have seriously affected the development of catalytic technology. Therefore, researchers are looking for inert materials with high specific surface area, high porosity, good thermal stability and excellent mechanical stability as carriers. Biochar is rich in functional groups on its surface, and it can be used as a carrier to support metal catalyst to alleviate metal agglomeration and effectively promote various catalytic reactions. This article reviews the research progress of metal-loaded biochar catalysts, briefly describes the advantages and disadvantages of different carbonization methods of metal-biochar catalysts, analyzes the effects of different modification treatments on catalytic performance, and reviews its use in biodiesel and bio-oil extraction, industrial applications in the fields of catalysis, such as quality, hydrogenation, tar cracking and electrochemistry. The possible mechanism of action in each catalytic reaction is analyzed, and references for the promotion of domestic metal-loaded biochar catalyst research and industrial development are provided.
