Decoration of Ag nanoparticles on CoMoO₄ rods for efficient electrochemical reduction of CO₂.

ABSTRACT: Hydrothermal and photoreduction/deposition methods were used to fabricate Ag nanoparticles (NPs) decorated CoMoO₄ rods. Improvement of charge transfer and transportation of ions by making heterostructure was proved by cyclic voltammetry and electrochemical impedance spectroscopy measurements. Linear sweep voltammetry results revealed a fivefold enhancement of current density by fabricating heterostructure. The lowest Tafel slope (112 mV/dec) for heterostructure compared with CoMoO₄ (273 mV/dec) suggested the improvement of electrocatalytic performance. The electrochemical CO₂ reduction reaction was performed on an H-type cell. The CoMoO₄ electrocatalyst possessed the Faraday efficiencies (FEs) of CO and CH₄ up to 56.80% and 19.80%, res
