Cerium Synchronous Doping in Anatase for Enhanced Photocatalytic Hydrogen Production from Ethanol-Water Mixtures.

ABSTRACT: Cerium element with a unique electric structure can be used to modify semiconductor photocatalysts to enhance their photocatalytic performances. In this work, Ce-doped TiO₂ (Ce/TiO₂) was successfully achieved using the sol-gel method. The structural characterization methods confirm that Ce was doped in the lattice of anatase TiO₂, which led to a smaller grain size. The performance test results show that the Ce doped in anatase TiO₂ significantly enhances the charge transport efficiency and broadens the light absorption range, resulting in higher photocatalytic performance. The Ce/TiO₂ exhibited a photocurrent density of 10.9 μA/cm² at 1.0 V vs. Ag/AgCl, 2.5 times higher than that of pure TiO₂ (4.3 μA/cm²
