TLDR
Nanostructuring tungsten diselenide nanoflakes enhances catalytic activity for carbon dioxide conversion to carbon monoxide in an ionic liquid medium and applies this catalyst in a light-harvesting artificial leaf platform that concurrently oxidized water in the absence of any external potential.Abstract:
Conversion of carbon dioxide (CO2) into fuels is an attractive solution to many energy and environmental challenges. However, the chemical inertness of CO2 renders many electrochemical and photochemical conversion processes inefficient. We report a transition metal dichalcogenide nanoarchitecture for catalytic electrochemical CO2 conversion to carbon monoxide (CO) in an ionic liquid. We found that tungsten diselenide nanoflakes show a current density of 18.95 milliamperes per square centimeter, CO faradaic efficiency of 24%, and CO formation turnover frequency of 0.28 per second at a low overpotential of 54 millivolts. We also applied this catalyst in a light-harvesting artificial leaf platform that concurrently oxidized water in the absence of any external potential.read more
