Abstract:
A novel and tunable synthesis of Fe/CuO bimetallic catalysts has been achieved via a simple Fe-precipitation and calcination method, which was used for highly efficient CO2 electroreduction to control the wide-ranging CO to H2 ratio by simply changing the ratio of metals. The faradaic efficiency of CO could reach 86.1% with a current density of 49.1 mA cm-2. The ratio of CO/H2 could reach 1.94 to 6.18 and it was discovered that the Fe/CuO bimetallic catalysts could easily get different ratios of syngas, which can be applied directly in industry.
