| Abstract: | The TiO2 film was prepared by sol-gel technology on a glass plate.Its microstructures,morphology and particle size of the sample were studied by an atom force microscope(AFM).Its thickness was measured by the elliptical polarized thickness meter.The catalytic principle of TiO2 particles and the particle size distribution of the thin film were studied.The test of photocatalysis which degrades the methyl orange solution by the nano TiO2 films shows that the TiO2 film of about 130 nm thickness can achieve the ... |
