摘要：
It was shown that the rate of the phototransformations of methylene blue and tetrachlorofluorescein at titanium dioxide is determined by the crystal structure and specific surface area of the titanium dioxide. Rutile has the highest specific photoactivity. In spite of the difference in the mechanisms both reactions have common limiting stages, as shown by correlation of the respective specific rate constants. © 2001 Plenum Publishing Corporation.
