研究了不同煅烧温度、煅烧时间的系列二氧化钛样品悬浮体系光催化降解X-3B活性艳红的催化活性.分析了晶粒尺寸、晶相、晶格畸变应力和光催化体系等诸多因素对二氧化钛光催化活性的影响.发现晶格畸变应力对空穴电子对复合速率的影响在诸因素中占主导地位,并在一定程度上决定了二氧化钛悬浮体系的光催化效能.
The catalytic activity of photocatalytic degradation of X-3B reactive brilliant red in a series of titania suspensions with different calcination temperature and calcination time was studied.The photocatalytic activities of photocatalytic degradation of X-3B reactive brilliant red were studied by many factors such as grain size, crystal phase, lattice distortion stress and photocatalytic system It is found that the effect of lattice distortion stress on hole electron pair recombination rate dominates the factors and to a certain extent determines the photocatalytic efficiency of the TiO2 suspension system.
