A simple demonstration of photocatalysis is presented. The demonstration is visual, simple to perform, and could easily be modified into a laboratory experiment. The mechanism of dye degradation by the photocatalyst is also discussed. In addition to illustrating a photocatalytic reaction, it is also an example of the reduction and oxidation of organic compounds and experimental design that link the catalysis to TiO2.
