Abstract:
... The greatest problem in conventional Fenton reaction is the slow production of ROS (reactive oxygen species) because of the inefficient Fe³⁺/Fe²⁺ conversion. Based on the extraordinary photo-response property of two-dimensional molybdenite (2DM), photogenerated electrons can be easy separated to accelerate the regeneration of Fe²⁺. In this work, Fe²⁺-anchored 2DM (2DM-Fe) was prepared and used as ...
