摘要：Textile industries are always deal with water pollution caused by pigments, one of which is organic compounds. Efforts have been made to treat the polluted water, however the methods still need to be improved. Cobalt-doped tin(IV) oxide (Sn1-xCoxO2, x = 0, 0.0025 and 0.005) prepared by a solid state reaction of SnO2 powder and cobalt nitrate salt has been introduced to catalysis of methyl orange photodegradation. The catalysts have band gap energy (Eg) varied between 1.813 and 3.944 eV, and indicates good responses in both visible and ultraviolet lights, having high potent as photocatalysts on methyl orange degradation. The test indicates the applicability of Langmuir adsorption isotherm for the systems.
