摘要: Abstract Mesoporous ZnO/TiO 2 hollow microspheres have been successfully synthesized by a facile one-step hydrothermal route without any template. The effect of reactants, temperature and time on the morphology photocatalytic degradation activity has investigated in details. with average diameter 0.5–2 μm showed time-dependent growth process consisted nanoparticles 10–20 nm. was evaluated via methyl orange (MO). Compared pristine TiO or ZnO nanosheets, produced significantly positive band-gap energy shift (from 3.16 eV (TiO ) to 2.80 eV (ZnO/TiO )) (with high apparent reaction rate 10.19 × 10 −2 min −1 probably owing hybrid microsphere their synergistic catalytic effect.
