摘 要: | A photocatalyst consisting of TiO2 powder and rectorite was prepared and activated utilizing solar light and used for degradation of simulated dye wastewater (methyl solution). The effects of roasting temperature, the way of adding rectorite, and the amount of the rectorite on the photocatalytic activity have been investigated. The results indicated that rectorite-TiO2 photocatalyst prepared with the right proportional amount of rectorite and titanium dioxide, could effectively degrade the methyl orange solution in sunlight. After reacting in sunlight for 8 hours, the methyl orange decolorization reached 96%. The photocatalytic activity of rectorite-TiO2 was much better than that of TiO2 in sunlight.
