Abstract
The present invention disclosed preparation method of a visible-light-driven CC@SnS/SnOcomposite catalyst, and application thereof, comprising the following steps: preparing CC@SnScomposite material in a solvent by using SnCl.5HO and CHNS as raw materials and carbon fiber cloth as a supporting material; calcining said CC@SnScomposite material to obtain the visible-light-driven CC@SnS/SnOcomposite catalyst. The present invention overcomes defects of the traditional methods of treating chromium-containing wastewater, including chemical precipitation, adsorption, ion exchange resin and electrolysis, and the photocatalytic technology can make full use of solar light source or artificial light source without adding adsorbent or reducing agent. In this case, the use of semiconductor photocatalyst to convert hexavalent chromium in chromium wastewater into less toxic and easily precipitated trivalent chromium greatly reduces the cost and energy consumption.
