Gold-like activity copper-like selectivity of heteroatomic transition metal carbides for electrocatalytic carbon dioxide reduction reaction
An overarching challenge of the electrochemical carbon dioxide reduction reaction (eCO(2)RR) is finding an earth-abundant, highly active catalyst that selectively produces hydrocarbons at relatively low overpotentials. Here, we report the eCO(2)RR performance of two-dimensional transition metal carb...

description | An overarching challenge of the electrochemical carbon dioxide reduction reaction (eCO(2)RR) is finding an earth-abundant, highly active catalyst that selectively produces hydrocarbons at relatively low overpotentials. Here, we report the eCO(2)RR performance of two-dimensional transition metal carbide class of materials. Our results indicate a maximum methane (CH(4)) current density of −421.63 mA/cm(2) and a CH(4) faradic efficiency of 82.7% ± 2% for di-tungsten carbide (W(2)C) nanoflakes in a hybrid electrolyte of 3 M potassium hydroxide and 2 M choline-chloride. Powered by a triple junction photovoltaic cell, we demonstrate a flow electrolyzer that uses humidified CO(2) to produce CH(4) in a 700-h process under one sun illumination with a CO(2)RR energy efficiency of about 62.3% and a solar-to-fuel efficiency of 20.7%. Density functional theory calculations reveal that dissociation of water, chemisorption of CO(2) and cleavage of the C-O bond—the most energy consuming elementary steps in other catalysts such as copper—become nearly spontaneous at the W(2)C surface. This results in instantaneous formation of adsorbed CO—an important reaction intermediate—and an unlimited source of protons near the tungsten surface sites that are the main reasons for the observed superior activity, selectivity, and small potential. |
