A simple experiment of gamma irradiated radiolytic versus radiocatalytic 4-chlorophenol degradation is presented. Samples of 4-chlorophenol solutions were put in contact with TiO2, Al2O3 and SiO2 ceramics and gamma irradiated. It was found that addition of these materials improve the degradation in a way similar to photocatalysis.
