Abstract

Delafossite CuCrO₂ and spinel CuCr₂O₄ with mesoporous structures have been successfully synthesized using nanocasting methods based on a KIT-6 template. The functional activity of the mesoporous materials was evaluated in applications as heterogeneous catalysts. The activity for photocatalytic hydrogen production of the delafossite structures with different morphologies was characterized and the oxidation state changes associated with photocorrosion of Cu⁺ investigated using electron energy loss spectroscopy (EELS). Mg²⁺ doping was found to facilitate the casting of ordered structures for CuCrO₂ and improves the photocorrosion resistance of delafossite structures. The mesoporous spinel CuCr₂O₄ nanostructures were found to be active for low temperature CO oxidation.
