摘要：

This article describes the synthesis of monoclinic WO3 nanostructures with highly reactive (002) facets exposed through a facile hydrothermal method using boric acid as the guiding agent. The obtained WO3 plate films exhibit an excellent photocurrent density of 1.64mA/cm2 at 1.2V (vs. Ag/AgCl) and an IPCE value of 66.7% at 355nm at a bias of 0.8V (vs. Ag/AgCl). Furthermore, a maximum 2.8-time higher formic acid yields was obtained in a versatile photoanode-driven PEC CO2 reduction system. The pronounced enhancement in photoelectrocatalytic acti...
