Abstract:Photoelectrochemical (PEC) water splitting and electrochemical carbon dioxide (CO 2 ) reduction have emerged as viable methods for future solar-to-chemical conversion. Among various candidates, copper oxide (CuO) stands out as a promising photocathode material due to its suitable optical band gap, favorable band alignment, and low cost. Here, we report a low-temperature solution process to fabricate CuO branched nanowires (b-NWs) to explore the effect of surface morphology on the activity of PEC water splittin… Show more
