Utility of carbon as a support for photocatalytic reaction of titanium dioxide has been demonstrated. Four kinds of carbon powder (NG, NY, WG and GF (fiber)) were used in this work. Ti0_2 powder was suspending together with various carbon powder in the PYLEX tube filled with aqueous dilute Methylene Blue (MB) solution, which is generally used as the evaluating agent for the photocatalytic reaction. The black light of 356nm with 9W was used and illumination was conducted for 10, 20, 30 and 40 minutes, respectively. After photo experiments, the concentration of MB in the solution senarated TiO_2 particles away by a centrifuge was measured by the absorptiometric method. Besides, the microstructure of each carbon was investigated by Xray diffraction analysis and electro conductivity was discussed. The results obtained are as follows. The carbon affected the catalysis reaction of TiO_2 particles to improve the reaction rate. The photocatalytic effect of TiO_2 is promoted with the absorption ability of carbon powders.
