摘要: Carbonaceous materials with superior catalytic activity, which could avoid drawbacks of heavy metal ion leaching for metal-based catalysts, are widely used in advanced oxidation processes ( AOPs). Biochar, a carbon-rich material produced by pyrolysis of biomass under oxygen limited condition, is low-cost, widely available, and environmentally friendly. Biochar has been utilized to activate peroxides such as hydrogen peroxide, peroxymonosulfate and peroxydisulfate for the degradation of pollutants in water. In this paper, precursors and preparation methods of biochar as well as their influence on catalytic activity of biochar are discussed. The activation mechanisms of peroxides by biochar and the effects of water matrices on the degradation of pollutants are summarized. The progress in the modification of biochar is reviewed. The reusability of biochar is elucidated and the regeneration methods of biochar are provided. In the end, the problems and the prospects of the biochar- based AOPs are put forward.
