Finding a suitable semiconductor material that harvests a large portion of the sunlight spectrum with high photocatalytic efficiency lies in the heart of photocatalysis. In this regard, black phosphorus (BP), a rising star two-dimensional (2D) semiconducting material, has recently been regarded as an abundant, nontoxic, metal-free, and cheap photocatalyst with a suitable bandgap and broad light absorption ability. In this chapter, after the introduction of the general properties and synthesis of BP, the photocatalytic efficiency of BP and BP-based composites in energy and environmental applications are summarized.Chemical engineeringBook Chapterhttps://www.scopus.com/inward/record.uri?eid=2-s2.0-85128060911&doi=10.1016%2fB978-0-12-823007-7.00007-9&partnerID=40&md5=5f6d0bba02cb0ddf2a3d1678e882c1fd10487
