PG - 141150 LID - S0045-6535(24)00043-2 [pii] LID - 10.1016/j.chemosphere.2024.141150 [doi] AB - Biomass-derived biochar shows broad promise for persistent organic pollutants (POPs) degradation and thus establishes a more sustainable homestead. However, effective catalytic performance is still challenging. Herein, an efficient catalyst (Prussian blue decorated wood-derived biochar, PBB) was constructed by introducing Prussian blue (PB) into wood-based biochar to activate peroxymonosulfate (PMS) for removing POPs. After anchoring of PB, the degradation performance of biochar was enhanced (degradation efficiency of methylene blue (MB, 20 mg/L) increased from 52% of biochar to 95% of PBB within 60 min). The PBB presents effective MB degradation performance with a wide pH value (3.0 < pH < 11.0) or co-existing diverse anions (Cl(-), NO(3)(-), H(2)PO(4)(-), and HCO(3)(-)). Electron paramagnetic resonance (EPR) analysis as well as electrochemical tests confirmed that the non-radical pathway ((1)O(2)) is the key to biochar activation of PMS, but by restricting PB into the biochar, the radical pathway (SO(4)(*-) and (*)OH), the non-radical pathway ((1)O(2)), and direct electron transfer can work together to activate PMS. In addition, the degradation efficiency could remain about 80% after five-time cyclic tests. This work elucidates the role of PB nanoparticles in enhancing biochar catalysts, which can inspire the development of a carbon-neutralized, cost-effective, and effective strategy for POPs removal.
