Semiconductors combine forces in photocatalysis

A significant advance in the photocatalytic activity of conventional materials is demonstrated by a two-dimensional heterostructure comprising nanolayers of two semiconductors: black phosphorus and bismuth tungstate. This catalyst harnesses the energy of visible light to split water and produce hydrogen, and to break down nitrogen monoxide in exhaust gas.
