Abstract
The design of highly active photocatalysts for degradation of phenol can be particularly challenging for solar energy utilisation. Herein, a series of mesoporousLaCo1−xCexO3catalysts have been synthesised and studied for degradation of phenol under UV irradiation. Compared with LaCoO3-SG catalyst which is formed through sol-gel method, optimised LaCo1−xCexO3-NC prepared by nanocasting method showed remarkably higher activity for the degradation of phenol due to the higher specific surface area, and the order of degradation rates is LaCo0.85Ce0.15O3-NC > LaCoO3-NC > LaCoO3-SG. Moreover, Au/LaCo1−xCexO3 catalysts were synthesized via Au deposition–precipitation method, and the catalytic activity for photodegradation of phenol increased with the loading of Au on the support.
