Abstract
In the present paper, mesoporous InVO4/TiO2 nanobelts with diameter about 400 nm have been synthesized by elaborately designed electrospinning process. The microstructures of InVO4/TiO2 nanobelts are characterized in detail, and their photoelectrocatalytic properties are comprehensively investigated by the photocatalytic degradation tests with tetracycline (TTC) and rhodamine B (RhB) waste water. Furthermore, the energy bandgap and density of states of orthorhombic InVO4 and anatase TiO2 are modeled and analyzed by density functional theory. Compared with single InVO4 nanobelts and TiO2 nanofibers, mesoporous InVO4/TiO2 nanobelts possess the extraordinary photocatalytic efficiencies and exceptional cycle performances, which may be ascribed to the successful construction of heterostructures between InVO4 and TiO2 and unique one‐dimensional belt structures.
