Black phosphorus (BP), a star-shaped two-dimensional material, has attracted considerable attention owing to its unique chemical and physical properties. BP shows great potential in photocatalysis area because of its excellent optical properties; however, its applications in this field have been limited to date. Now, a Z-scheme heterojunction of 2D/2D BP/monolayer Bi WO (MBWO) is fabricated by a simple and effective method. The BP/MBWO heterojunction exhibits enhanced photocatalytic performance in photocatalytic water splitting to produce H and NO removal to purify air; the highest H evolution rate of BP/MBWO is 21042 μmol g , is 9.15 times that of pristine MBWO and the NO removal ratio was as high as 67 %. A Z-scheme photocatalytic mechanism is proposed based on monitoring of O , OH, NO , and NO species in the reaction. This work broadens applications of BP and highlights its promise in the treatment of environmental pollution and renewable energy issues.
黑磷（BP）是一种星形二维材料，因其独特的化学和物理性质而备受关注。由于其优异的光学性质，BP在光催化领域显示出巨大潜力；然而，迄今为止其在该领域的应用仍然有限。现在，通过一种简单有效的方法制备了二维/二维BP/单层BiWO（MBWO）的Z型异质结。BP/MBWO异质结在光催化水分解制氢和去除NO以净化空气方面表现出增强的光催化性能；BP/MBWO的最高析氢速率为21042 μmol g，是原始MBWO的9.15倍，NO去除率高达67%。基于对反应中O 、OH、NO 和NO 物种的监测，提出了一种Z型光催化机理。这项工作拓宽了BP的应用范围，并突出了其在环境污染治理和可再生能源问题方面的前景。
