摘要
研究了用分子筛MCM多孔材料作载体,制备负载型MCM-TiO2和MCM-TiO2/Pd催化剂。用X-衍射(XRD)对样品进行了表征,在带CCD的T-64000型色散光谱仪上得到了样品的拉曼光谱。比较了样品对对甲基苯酚的光催化降解性能,并探讨了不同温度焙烧样品对对甲基苯酚光降解率的影响。
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.
