Graphene oxide immobilized binuclear biomimetic catalyst for triclosan degradation in aqueous solution

Biomimetic catalysts, Zn(salen), Zn(Phe-TPP), ZnPSC6 and graphene oxide (GO) immobilized ZnPSC6 (ZnPSC6/GO), were fabricated. These biomimetic catalysts were tested for catalytic decomposition of emerging contaminant triclosan (TCS). Catalysts were characterized using Brunauer-Emmett-Teller (BET), X...
