A simple cadmium sulfide nanomaterial is found to be an efficient and stable electrocatalyst for CO2 reduction in aqueous medium for more than 40 h with a steady CO faradaic efficiency of approximately 95 %. Moreover, it can realize a current density of −10 mA cm−2 at an overpotential of −0.55 V on a porous substrate with similar selectivity. Theoretical and experimental results confirm that the high selectivity for CO2 reduction is due to its (0 0 0 2) face with sulfur vacancies that prefers CO2 molecule reduction in aqueous medium.

简单的硫化镉化合物,在水介质中具有稳定的95%选择性,可用于二氧化碳电还原
发现一种简单的硫化镉纳米材料是在水性介质中还原CO 2超过40小时的有效且稳定的电催化剂,其稳定的CO法拉第效率约为95%。此外,在具有相似选择性的多孔基板上,在-0.55V的过电势下,可以实现-10mA cm -2的电流密度。理论和实验结果证实,CO 2还原的高选择性归因于其(0 0 0 2)面带有硫空位,因此更喜欢在水性介质中还原CO 2分子。
