摘要:

Conventional photoelectrochemical cells utilize solar energy to drive the chemical conversion of water or CO2 into   useful chemical fuels. Such processes are confronted with general challenges, including the low intrinsic activities and inconvenient storage and transportation of their gaseous products. A photoelectrochemical approach is   proposed to drive the reductive production of industrial building-block chemicals   and demonstrate that succinic acid and glyoxylicacid can be readily synthesized on Si nanowire array photocatho des free of any cocatalyst and at room temperature. These photocathodes exhibit a positive onset potential, large saturation photocurrent density, high reaction selectivity, and excellent operation durability. They capitalize on the large photovoltage generated from the semiconductor/electrolyte junction to partially offset the required external bias, and thereby make this photoelectrosynthetic approach significantly more sustainable compared to traditional electrosynthesis
