摘要
A nano-structured YiO2 wkh rutile phase was synthesized by using the hydrothermal method from a titanium carbide （TIC） nano-powder precursor at low temperature to produce a stable visible light responsive photoeatalyst. The rutile phase was formed at temperature as low as 100℃, and both synthesis time and temperature affected its formation. The rutile particles showed a faceted nano-rod structure, and were tested fbr absorption and photo-degradation ability under visible light. Particles with shorter synthesis times showed higher visible light absorption and corresponding photo-degradation ability, while those synthesized at lower tempe, ratures had lower, but still evident, degradation ability under visible light.
