Water-mediated electro-hydrogenation of CO2 at near-equilibrium potential by carbon nanotubes/cerium dioxide nanohybrids

The combination of multiwalled carbon nanotubes (MWCNTs) with undoped CeO2 nanoparticles (NPs) is effective for the di-rect electrocatalytic reduction of CO2 to formic acid (FA) at acidic pH (HNO3 ...
