Achieving electroreduction of CO 2 to CH 3 OH with high selectivity using a pyrite–nickel sulfide nanocomposite
Electrochemical reduction of carbon dioxide (CO2) to methanol (CH3OH) catalyzed by
transition metals has been proved feasible and effective in aqueous electrolytes. In this
work, we introduce a FeS2/NiS nanocomposite electrocatalyst synthesized by traditional
hydrothermal method, which selectively reduces CO2 to CH3OH with an unprecedented
overpotential of 280 mV and a high faradaic efficiency up to 64% at the potential of− 0.6 V
vs. reversible hydrogen electrode (RHE). The FeS2/NiS nanocomposite electrocatalyst …
