| Abstract: | In this article, composites of photocatalyst TiO_2 and carbon are reviewed. It is pointed out that composites exhibit a diversity of characteristics: carbon is not only used as a support but a coating, pore-forming agent and doptant. Correspondingly, carbon in the composite has the effects of concentrating the targeted pollutant and capturing intermediate products, besides it has advantages of suppressing the phase transformation from anatase to rutile and preventing sintering and crystal growth in TiO_2 particles at high temperatures. It can also extend the optical absorption band of composite photocatalyst to the visible spectral region. Therefore, it has a beneficial effect on the practical application of photocatalysis technology for carbon/TiO_2 composite photocatalyst. |
