摘要
以醇盐法合成的TiO_2超微粉为光催化剂,研究了光催化还原Cr_2O_7^(2-)的反应,找到了最佳处理条件,并综合运用SPS,XRD、TEM等手段对光催化剂进行了考察,确认TiO_2超微粉是一种效率很高可望有良好应用前景的光催化剂。最后对光催化反应机理进行了讨论。
In this paper,the TiO2 UFP photocatalyst was synthesized by the hydrolysis of metal alkoxide.Photocatalysis of reducing Cr2O72- was studied.The optinum condition for treatment was found out.SPS,TEM and XRD were applied to examine the photocatalyst.The TiO2 UFP exhabits a promise photocatalyst with high efficiency and has good application prospects.Finally,the reaction mechanism was discussed.
