Ultralow-temperature CO oxidation on an In2O3–Co3O4 catalyst: a strategy to tune CO adsorption strength and oxygen activation simultaneously†
Abstract
Highly efficient In2O3–Co3O4 catalysts were prepared for ultralow-temperature CO oxidation by simultaneously tuning the CO adsorption strength and oxygen activation over a Co3O4 surface, which could completely convert CO to CO2 at temperatures as low as −105 °C compared to −40 °C over pure Co3O4, with enhanced stability.
