Abstract Construction of core–shell structured electrocatalysts with a thin noble metal shell is an effective strategy for lowering the usage and improving electrocatalytic properties because structure‐induced geometric electronic effects. Here, synthesis novel nanocatalyst consisting amorphous Pd crystalline PdCu core its significantly improved both formic acid oxidation oxygen reduction reactions are shown. The electrocatalyst exhibits 4.1 times higher catalytic peak current density better...
Electrocatalytic conversion of carbon dioxide (CO2) to value-added hydrocarbon products provides an industrially viable approach utilizing resources and the storage renewable energy. Monovalent copper (Cu+) has been demonstrated be indispensable for formation C2+ via C–C coupling. However, selectivity stability Cu+ at cathodic potential remain a great challenge. In this work, we investigated electrochemical properties three Cu-based catalysts with different structures in electrocatalytic...
Adsorbed metal atoms and doping onto TiO₂ can effectively enhance the optical photocatalytic activity of efficiency titanium dioxide (TiO₂), favoring extension its absorption spectrum hydrogen generation. To investigate possible mechanism causing potential improvement activity, electronic properties anatase TiO₂(101) plane with different adsorbed atom have been theoretically calculated through density functional theory (DFT) method. Adsorption Pd Ru increases delocalization states, an...
Accelerating the separation and migration of photo-carriers (electron-hole pairs) to improve photo-quantum utilization efficiency in photocatalytic overall water splitting is highly desirable. Herein, photo-deposition Ru or Au noble metal clusters with superior electronic properties as a co-catalyst on (101) facet anatase TiO2 mechanism intensifying photocatalysis have been investigated by calculation based density functional theory (DFT). As result, as-synthesized Ru/TiO2 Au/TiO2 exhibit...
With the rapid development of fuel cell technology, low reduction rate oxygen on Pt-based cathodes is generally considered main obstacle. Pt/transition metal alloys (Pt-Ms) or oxides (Pt-MO x ) can be formed by doping transition atoms into lattice Pt layer depositing onto surface to intensify catalytic activity electrodes. In this work, a stepwise solution chemical method for high dispersion cobalt oxyhydroxide (-OCoOH) deposited facet as nano-islands and mechanism promoting reaction (ORR)...
