主 题：Biochar-based catalysts Sonocatalysts Fenton-like catalysts Photocatalysts Pollutant removal Environmental risks
摘 要：As a carbon-rich material produced by pyrolysis of biomass,biochar features low cost,large specific surface area,and widely available feedstocks based on the functional diversity and environmental-friendly properties,it has received increasing attention in the fields of pollutant removal due to three win-win effects of water remediation,carbon sequestration and reutilization of wastes.To design excellent biochar-based catalysts for environmental applications,one must understand recent advances in the catalysts for contaminant removal.This review focuses on the current application of biochar-based catalysts in redox systems,Fenton-like systems,sonocatalytic systems and photocatalytic systems.Besides in-depth discussion in effects of preparation conditions on physicochemical characteristics of biochars,the review supplements new preparation technologies of biochar and biochar-based catalysts.Most importantly,the advantages/shortcomings,catalysis mechanisms,as well as the pollutant removal ability of different types of biochar-based catalysts are discussed.The environmental risks of the catalyst applications are also elaborated on.Future research on biochar-based catalyst production and its environmental applications is discussed.The review provides a good overview of the current advances of biochar-based catalysts in pollutant control and the future research directions.
