| dc.abstract.en | There has been growing interest in preparation of the advanced catalytic systems that efficiently utilize nanosized materials with well-defined composition, structure, thickness and desirable electrocatalytic properties. The ability of polynuclear inorganic metal oxo systems to support, stabilize and functionalize catalytic metal nanostructures is explored here. Certain nanostructured metal oxides, including oxides of zirconium and tungsten, have been demonstrated to influence catalytic metal centers in ways other than simple dispersion over electrode area. Evidence is presented that the support can modify activity (presumably electronic nature) of catalytic metal nanoparticles (e.g. Cu), thus affecting their chemisorptive and catalytic properties. Metal oxide (ZrO2, WO3) nanospecies can generate –OH groups at electrocatalytic interface. Our electrocatalytic results with copper nanostructures over-coated with ZrO2 or WO3 nanostructures imply the systems’ improved selectivity toward CO2-reduction relative to the competitive hydrogen evolution as well as the lower tendency of copper sites to undergo poisoning. |
