WO₃ in suit embed into MIL-101 for enhancement charge carrier separation of photocatalyst.

ABSTRACT: Compositing nanoparticles photo-catalyst with enormous surface areas metal-organic framework (MOF) will greatly improve photocatalytic performances. Herein, WO₃ nanoparticles are partly embedded into pores of MIL-101 or only supported on the outside of representative MIL-101, which were defined as embedded structure WO₃@MIL-101@WO₃ and coating structure WO₃&MIL-101 respectively. Different pH, concentration and loading percentage were researched. XRD, TEM and BET were carried to analyze the composites. Compared with the pristine WO₃, all WO₃ loaded MOF nanocomposites exhibited remarkable enhancing for the efficiency of photocatalytic degradation methylene blue under visible light. Their activity of the same loading percentage
