The TiO2-graphene oxide-Hemin ternary hybrid composite material as an efficient heterogeneous catalyst for the degradation of organic contaminants
TiO2-Graphene Oxide-Hemin (TiO2/GO/Hemin) ternary composite hybrid material was prepared by the sol-gel method and used as a heterogeneous catalyst for the photocatalytic degradation of organic contaminants. The catalytic activity of GO-TiO2-Hemin was evaluated by the degradation of Rhodamine B (RhB...
