Abstract: A visible light activatable mesoporous titanium dioxide photocatalyst having a surface area of from 100 m2/g to 400 m2/g. The photocatalyst may have a rate of decomposition greater than 0.005 min?1. The photocatalyst may have a band gap width less than 2.95 eV. The photocatalyst may comprise undoped titanium dioxide or doped titanium dioxide. A hydrothermal process for synthesising a photocatalyst is also described.
