The safe disposal and resource utilization of heavy metal contaminated biomass has long posed a huge challenge. The direct preparation of heavy metal-contaminated straw into a biomass-derived multi-metal loading heterogeneous Fenton catalyst (BHFC) through pyrolysis for thiamethoxam (THX) degradation is a win–win strategy to address this problem. In this method, Fe, Mn, Cu, and Zn in contaminated biomass collected from mineral areas are released as active metals and loaded in the form of metal oxides on biomass pyrolysis biochar with a mesopor...
