摘要: Abstract Flower-like anatase TiO 2 hierarchical spheres assembled by nanosheets were synthesized glycine assistant via a simple hydrothermal approach and after-annealing process. These flower-like are about 2 μm in diameter with sheet thickness 20 nm. Results showed reaction time, temperature, solution pH dosage all played an important role control of shape size the as-synthesized nanocrystals. The photocatalytic activity this nano-TiO was evaluated oxidation decomposition methyl orange under sunlight illumination presence hydrogen peroxide (H O ). obtained higher than that commercial .
