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 O₂⁻ radicals.
