Synthesis,characterizationandphotocatalyticactivityofC0^2＋-dopedtitania

Photocatalyst of Co^2＋-doped titania was simply prepared,and thephotocatalytic activity was tested under UVirradiation for methyl orange degradation.The influence of doping quantity,calcination temperature,calcination time and quantity of catalyst was investigated for photocatalytic efficiency of the photocatalyst.The sample was characterized by UV diffuse reflectance spectra （UV/DRS）.X-ray diffraction （XRD）,X-ray photoelectron spectroscopy （XPS）,transmission electron microscopy（TEM）and IR.Theresults showed that thephotocatalytic activity Co^2＋doped Tio2 which calcined at200℃ for 5h iS high,and which diameter is about 4.7nm presents anatase phase.The sample absorption band of UV/DRS moves to visible region and reaches 580 nm.This kind of catal yst is also effective for degradation other organic dyes and beer wastewater.
