“…Pt–Rh-based materials have attracted a great deal of attention in the last years due to their wide range of catalytic applications, including the preferential oxidation of CO in hydrogen, , the control of NO x and CO emissions from car exhaust, the hydrogen evolution reaction, formic acid oxidation, , and the hydrogenation of organic compounds, , among others. Furthermore, Pt–Rh-based materials have been explored as catalysts for proton exchange membrane fuel cells (PEMFCs), both in the cathode and in the anode, where they have been investigated for the oxidation of methanol , and ethanol − or as CO-tolerant hydrogen oxidation reaction (HOR) catalysts. , …”
