| Abstract: | The photocatalysts consisted of TiO2 and TiO2/Pd loaded on MCM were prepared respectively. Nano-crystalline TiO2 and TiO2/Pd particles of samples were characterized using XRD. The samples Raman spectroscopy was obtained by model T-64000 color-scattering spectrometer with CCD. The property of photocatalytic degradation of the samples towards p-methyl phenol was compared. Moreover,photodegradation rate of p-methyl phenol on samples calcinated at different temperature was studied. |
