中文摘要：
采用传统固相合成法制备了BaTi403光催化剂，并利用XRD和UV-Vis光谱分析对催化剂进行了表征。选用甲基橙作为光催化活性的染料模型，研究了Pt的负载量对BaTi409光催化活性的影响，并对其影响机制进行了初步的探讨。实验表明，n的负载对光催化活性影响很大，当Pt的负载量为BaTi403。质量的0．5％时光催化效果达到最好。
英文摘要：
BaTi409 photo catalyst was prepared by a conventional solid-state method and the catalyst was characterized by X-ray powder diffraction and UV-Vis diffusive reflection spectra. Pt was loaded on the BaTi409 photo catalyst using a wet method. Their photocatalytic activities were investigated on the degradation of methyl orange. The results showed that the amount of Pt loaded on the BaTi409 catalyst greatly influenced its photocatalytic activities. The photo catalytic activity of the Pt-loaded photo catalyst was better than the catalyst without loading. Best photo catalytic activity occurred when the loading amount was 0.5%.
