Au-Ir/TiO2 were studied for MCP ring opening. Addition of gold increases the reactivity of Ir/TiO2 at low temperature and modulates the cracking activity preserving a high selectivity for RO products. Calcined-reduced samples were more active than reduced ones. Structure of the catalysts includes NP, clusters and isolated atoms.
