We developed a postgrowth modification method of two-dimensional WO3
nanoflakes by a simultaneous solution etching and reducing process in a weakly acidic condition.
The obtained dual etched and reduced WO3 nanoflakes have a much rougher surface, in which
oxygen vacancies are created during the simultaneous etching/reducing process for optimized
photoelectrochemical performance. The obtained photoanodes show an enhanced photocurrent
density of∼1.10 mA/cm2 at 1.0 V vs Ag/AgCl (∼1.23 V vs reversible hydrogen electrode), compared
to 0.62 mA/cm2 of pristine WO3 nanoflakes. The electrochemical impedance spectroscopy measurement
and the density functional theory calculation demonstrate that this improved performance of dual etched and reduced WO3 nanoflakes is
attributed to the increase of charge carrier density as a result of the synergetic effect of etching and reducing.

我们由蚀刻和减少进程在弱的酸性条件下的联立求解二维 WO3nanoflakes postgrowth 改性方法。获得双重蚀刻和减少 WO3 纳米片有很多粗糙的表面,在 which oxygen 在 optimizedphotoelectrochemical 性能的同时减少刻蚀/过程中创建的空缺。获得光阳极在 1.0 V vs 银/氯化银 (~1.23 V vs 可逆氢电极),相比于 0.62 马/cm2 的原始 WO3 纳米片显示增强的 photocurrentdensity of~1.10 mA/cm2。电化学阻抗谱法所得的密度泛函理论计算表明,这提高协同效应的蚀刻和减少电荷载流子密度的增加双重蚀刻和减少 WO3 纳米片 isattributed 的性能。
