Some experts have prepared Ce doped tungsten trioxide by hydrothermal method using cesium chloride and tungsten chloride as precursors. And the experts used the prepared photocatalytic material of Ce-doped tungsten trioxide for the visible light catalytic degradation of the dye methyl orange. The research results indicate:

As the mass ratio of W to Ce decreases, the morphology of the obtained product gradually changes from one-dimensional nanowires to agglomerated particles. When the mass ratio of W to Ce is 15:1, the obtained composite has the highest photocatalytic degradation efficiency to methyl orange in the water. Experts have said that the reason why Ce doped tungsten trioxide has excellent photocatalytic degradation efficiency is due to the good photocatalytic performance of WO3 itself, and the doping of Ce also plays an important role. In a word, Ce doped WO3 powder has better photocatalytic performance than tungsten trioxide powder.
