Abstract
Microstructured InVO4/WO3 heterojunctions were fabricated by a facile hydrothermal method and investigated in the photocatalytic degradation of rhodamine B (Rh.B) under simulated solar light. Embedding InVO4 into microhollow WO3 demonstrated efficient charge separation at the interface in essence. An interesting synergetic effect between InVO4 and WO3 led to an improved photocatalytic performance. However, the dropping of photoelectrochemical properties was tentatively deduced in the mechanism of charge recombination between electrons generated from WO3 and holes from InVO4. The tunnel effect has promoted the formation of electron/hole pairs with high redox potentials. However, it reduced the number of electrons to some extent.
