摘要
Peroxymonosulfate (PMS), peroxydisulfate (PDS) and hydrogen peroxide (H2O2)-based advanced oxidation processes are extensively applied for aqueous pollutants degradation. However, few cases reported the comparison the PMS, PDS and H2O2 activation performances of a heterogeneous catalyst. In this work, 1,1′-ferrocenedicarboxylate (Fc) modified Bi-BDC (Bi-BDC-Fcx) with unique electronic structure and strong oxidation ability was synthesized and applied for degrading bisphenols (BPs) via photocatalytic PMS, PDS, and H2O2 activation, respectively. The optimum Bi-BDC-Fc0.1 exhibited the best photocatalytic PMS, PDS and H2O2 activation performance to degrade various organics pollutants, including BPs, in which the bisphenol A degradation efficiencies followed the order of Bi-BDC-Fc0.1/UVL/PMS, Bi-BDC-Fc0.1/UVL/PDS and Bi-BDC-Fc0.1/UVL/H2O2. The reaction mechanisms of photocatalytic PMS, PDS and H2O2 activation over Bi-BDC-Fc0.1 were comprehensively clarified by experimental results along with DFT calculations. Also, the toxicity and ecotoxicological impact of the pristine BPs and their intermediates were evaluated by the phytotoxicity experiments and zebrafish early-life stage toxicity test. This work presented a comprehensive investigation of degradation performance and the ecotoxicology assessment of Bi-BDC-Fcx/UVL/PMS, Bi-BDC-Fcx/UVL/PDS, and Bi-BDC-Fcx/UVL/H2O2 systems, providing valuable insights to design and utilize the newly developed catalysts for water purification.
