摘要

Herein, CdS nanorods (CdS-NR) was synthesized through a simple and facile solvothermal method. XRD pattern and TEM/HRTEM images indicated that hexagonal CdS nanorods with a diameter of 10 nm were successfully prepared. When used as electrocatalyst for CO2 reduction reaction (CO2RR), CdS-NR afforded an excellent electrocatalytic performance in aqueous electrolyte. In comparison with commercial CdS nanoparticles (CdS-NP), CdS-NR could trigger the electroreduction of CO2 to CO with a higher faradic efficiency and current densities. The enhanced electrochemical performance of CdS-NR than that of CdS-NP were ascribed to its enhanced adsorption of CO2, charge transfer ability and more exposed active sites. More importantly, it was noticed that H2 generated along with CO, and the generated gas products with controllable ratios exhibited impressive potentials to directly using as syngas.
