摘要
We have impregnated chromium(III) onto a high surface area particulate niobium oxide to make bulk oxide-oxide interfaces, identifying by a combination of X-ray photoelectron spectroscopy and diffuse reflectance the exact energy of the metal-to-metal charge transfer transition that is responsible for the visible light photocatalytic decomposition of methyl orange.
