| Abstract: | Diffuse reflectance spectroscopy of supported CuO–TiO2 catalysts have revealed that, depending on the CuO content and the calcination temperature, either Cu2+ ions incorporated into the TiO2 lattice, or surface oxide clusters, primary oxide aggregates and CuO1+X phase bonded to the support by Ti–O–Cu bridges, are formed.
