自发性太阳能驱动水分解产生H2和O2，即太阳能转化为化学能是人类的梦想。然而，在不使用任何牺牲剂和外部偏压的情况下，难以使整体水裂解可行。从自然界中汲取灵感，本文基于黑磷（BP）/钒酸铋（BiVO 4）的二维（2D）异质结构设计了一种新的人工Z-方案光催化体系。有效的电荷分离使得水分别在BP和BiVO 4上的还原和氧化成为可能。在波长大于420 nm的光照射下， BP/BiVO 4上的最佳产氢和产氧速率分别约为160和102μmol g−1h− 1。
Spontaneously solar‐driven water splitting to produce H2and O2, that is, the conversion of solar energy to chemical energy is a dream of mankind. However, it is difficult to make overall water splitting feasible without using any sacrificial agents and external bias. Drawing inspiration from nature, a new artificial Z‐scheme photocatalytic system has been designed herein based on the two‐dimensional (2D) heterostructure of black phosphorus (BP)/bismuth vanadate (BiVO4). An effective charge separation makes possible the reduction and oxidation of water on BP and BiVO4, respectively. The optimum H2and O2production rates on BP/BiVO4were approximately 160 and 102 μmol g−1h−1under irradiation of light with a wavelength longer than 420 nm, without using any sacrificial agents or external bias.
