Abstract
Enhanced Photocatalytic Activity of Polyvinylpyrrolidone Assisted Microwave Hydrothermal Grown Tin Oxide Photocatalysts
Pure and well mono-dispersed SnO2 nanoparticles were synthesized by a microwave assisted hydrothermal method, where polyvinylpyrrolidone (PVP) was used as a surfactant and SnCl2.2H2O, as tin source. The structure and surface morphology of as-obtained products were well characterized by X-ray diffraction, scanning electron microscope and UV-Vis diffuse reflectance spectroscopy. The results show that the particle size of SnO2 nanoparticles is about 200-300 nm and there are many small prisms grown on SnO2 nanoparticles surface.
