摘要：Zn2SiO4 nanocrystallines were synthesized by a low-temperature hydrothermal method, in which the composition and morphology were tailored by changing the hydrothermal temperature and pH value. Zn2SiO4 was applied as novel photocatalyst to degrade various organic pollutants and it exhibited excellent photocatalytic activity and stability as compared to traditional ZnO. The better photocatalytic performance of Zn2SiO4 than ZnO can be attributed to the more generated charge carries, the stronger oxidation ability of h(+) and the higher concentration of active center dot O-2(-) radicals.
