چکیده
A three compartment solar formic acid generator was built using a Sn on Cu foam cathode and NiFe anode. bipolar combination of Fumasep FAD-PET-75 Nafion 117 membrane mounted between anode middle compartment, which filled with Amberlyst 15H ion exchanger beads. separated the from cathode. The powered photovoltaic panel fed gaseous CO 2 water. Diluted solution produced by flowing water through compartment. Common PV-EC devices are operated aqueous electrolyte produce formate. In our device, is straight away, avoiding need for downstream operations to convert formate acid. electrolyser matched cells achieving coupling efficiency as high 95%. Our device produces at faradaic ca. 31% solar-to-formic 2%. By producing without any additional chemicals this concept attractive use remote locations abundant energy. Formic serves liquid renewable fuel or chemical building block.

Solar conversion of CO2 to CO using Earth-abundant electrocatalysts prepared by atomic layer modification of CuO
The solar-driven electrochemical reduction of CO2 to fuels and chemicals provides a promising way for closing the anthropogenic carbon cycle. However, the lack of selective and Earth-abundant catalysts able to achieve the desired transformation reactions in an aqueous matrix presents a substantial impediment as of today. Here we introduce atomic layer deposition of SnO2 on CuO nanowires as a me...
