The migration of reducible metal oxides (for example, TiO2) to the surface of metal nanoparticles can inhibit sintering but has a strong negative impact on the catalytic activity. Here we reveal the in situ creation of TiOx patches over an MnO support to generate effective transport channels for hydrogen spillover to form more active hydrogen species on the MnO surface which are responsible for reducing CO2 to CO, a key reaction for CO2 conversion to high-value chemicals.
