Spontaneously solar‐driven water splitting to produce H₂ and 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 H₂ and O₂ production rates on BP/BiVO₄ were approximately 160 and 102 μmol g⁻¹ h⁻¹ under irradiation of light with a wavelength longer than 420 nm, without using any sacrificial agents or external bias.

可见光在黑色磷/钒酸铋的二维异质结构上进行Z方案光催化水分解

自发地由太阳能驱动的水分解产生H ₂和O ₂，即将太阳能转化为化学能是人类的梦想。但是，在不使用任何牺牲剂和外部偏压的情况下，很难使整个水分解可行。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型的人工Z方案光催化系统。有效的电荷分离使得分别在BP和BiVO ₄上还原和氧化水成为可能。BP / BiVO ₄的最佳H ₂和O ₂生产率在不使用任何牺牲剂或外部偏压的情况下，在波长大于420 nm的光照射下，它们分别约为160和102μmolg ^-1 h ^-1。
