H2O2 scission-driven •OH species are vital in oxidizing aqueous pollutants. H2O2 scission cycle is primarily featured by two elementary stages such as the desorption of •OH from Mδ+ species (M: metal, δ≤2) and the recovery of Mδ+ species through the reduction of M(δ+1)+ analogues by electrons (e-) fed by adjacent anions (S2-). This presentation summarizes our recent study on the utilization of metal sulfides as H2O2 crackers, the inspection of their Lewis acidic strengths and e- donating abilities via CO2 adsorption isotherm and linear scanning voltammetry techniques, respectively. In addition, •OH productivities on the metal sulfides are assessed and contrasted using a host of kinetic runs, while their degradation consequences of aqueous aromatic pollutants are also highlighted. |
