Role of pyridine in photoelectrochemical reduction of CO2 to methanol at a CuInS2 thin film electrode

Abstract

The crystal size and composition of CuInS₂, coverage of pyridine at the CuInS₂ thin film photocathode and the applied bias have significant effects on methanol yield in photoelectrochemical reduction of CO₂. The mass transfer resistance resulting from the pyridine adsorption layer is proposed to be the determining step.
