Little do more: a highly effective Pt1/FeOx single-atom catalyst for the reduction of NO by H2

A FeOx supported Pt single-atom catalyst (Pt-SAC) exhibited much higher NO conversion and selectivity to N-2 than the supported Pt nanocatalyst (Pt-Nano). This better performance was attributed to not only the stronger NO adsorption and easier dissociation of the N-O bond but also the presence of more oxygen vacancies on the Pt-SAC.
