Electrospun Mesoporous InVO₄/TiO₂ Nanobelts with Enhanced Photocatalytic Properties

Abstract

Abstract In the present paper, mesoporous InVO 4 /TiO 2 nanobelts with diameter about 400 nm have been synthesized by elaborately designed electrospinning process. The microstructures of InVO 4 /TiO 2 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 InVO 4 and anatase TiO 2 are modeled and analyzed by density functional theory. Compared with single InVO 4 nanobelts and TiO 2 nanofibers, mesoporous InVO 4 /TiO 2 nanobelts possess the extraordinary photocatalytic efficiencies and exceptional cycle performances, which may be ascribed to the successful construction of heterostructures between InVO 4 and TiO 2 and unique one‐dimensional belt structures.
