Application of Biochar-Based Metal Catalyst and Their Uses

Biochar-based transition metal catalysts have been identified as excellent peroxymonosulfate (PMS) activators for producing radicals used to degrade organic pollutants. The severity of environmental pollution has increased. These pollutants can pose a critical threat to humans, animals, and ecosystems. The creation of efficient treatment methods for eliminating pollutants from the environment is required to promote socially sustainable development and safeguard human health. Biochar materials have proven to be more effective as a catalyst or catalyst support in a wide range of applications, including transesterification and esterification, catalytic reforming and cracking, gasification and pyrolysis, hydrolysis, electrochemical reactions, photocatalysis, and persulfate/peroxymonosulfate oxidation, among many others. Various processes for the synthesis of biochar and its modification were discussed in this study.
