Abstract

Self-assembled three-dimensional InVO ₄ microspheres consisting of nanoparticles were synthesized by a facile template-free hydrothermal method. The resulting InVO ₄ microspheres had high crystallinity, and were of about 4.5 μm in diameter. The band-gap energy estimated from the main absorption edges of the UV-vis diffuse reflectance spectrum was 2.4 eV. Compared to the same material created via a solid-state reaction method, the InVO ₄ microspheres exhibited enhanced photocatalytic activities in the degradation of Rhodamine B(RhB) under visible light irradiation, which was mainly attributed to their higher surface area, and improved light-absorbing ability resulting from their unique morphology and variation of their crystal structure.
