Hydroxyl radical (•OH) generated from the activation of hydrogen peroxide (H2O2) on Fe2+ species is widely used to decompose an aqueous organic contaminant. Catalytic •OH evolution is conventionally enabled by Fe2+ ions-mediated H2O2 scission via homogeneous catalysis, yet, suffers from a variety of constraints including sludge formation, one-time utilization, narrow pH span, etc. In this presentation, an iron oxide-coated stainless steel mesh serves as an electrode to activate H2O2 via heterogeneous catalysis multiple times. For this purpose, a stainless steel mesh is sintered with FeAl powders under an Argon atmosphere to increase the surface area prior to being dip-coated with iron oxide powders. This presentation also details the comparison of homogeneous versus heterogeneous catalysis in degrading an aqueous pollutant. |
