| Abstract: | Micro sized particles of TiO 2 doped with Co have been prepared by way of titanic chloride hydrolysis,with cobaltous nitrate being used as dopant.Properties of the samples are characterized by means of XRD (X ray diffraction),and the gas phase photocatalytic activity is evaluated.The effect of pH on phase transformation has been examined.It is shown that the smaller the pH value,the lower the transformation temperature will be.The effect of Co doping on photocatalytic activity has also been studied.Toluene conversion improves remarkably with the addition of Co doped catalyst.Under experimental conditions,the service life of catalyst can be prolonged by nearly three times. |
