Abstract :
TiO2SiO2MgO catalyst was prepared and the OH radicals formed on the catalyst contacted with water were studied by the spin-trapping method. The condition of the catalyst surface that can produce OH radicals is optimized. The initial concentration of OH radicals on the surface does not influence the rate of the photocatalytic decomposition of hydrogen peroxide.
