摘要	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. The Ru/(TiOx)MnO (Ru/Ti/Mn) catalyst shows a 3.3-fold increase in reverse water-gas shift performance compared with conventional Ru/MnOx catalysts. Through a combination of physicochemical methods, including in situ studies, catalytic and kinetic data, and theoretical modelling, we demonstrate that the oxide-oxide interfaces are spontaneously generated during reductive treatment in H-2, contributing to the increased activity. The results open perspectives for the design of novel selective hydrogenation catalysts via the in situ creation of oxide-oxide interfaces acting as hydrogen-species transport channels.
