dc.description.abstract |
A cation exchange-based route was used to produce CuZnSnS (CZTS)-AgS nanoparticles with controlled composition. We report a detailed study of the formation of such CZTS-AgS nanoheterostructures and of their photocatalytic properties. When compared to pure CZTS, the use of nanoscale p-n heterostructures as light absorbers for photocatalytic water splitting provides superior photocurrents. We associate this experimental fact to a higher separation efficiency of the photogenerated electron-hole pairs. We believe this and other type-II nanoheterostructures will open the door to the use of CZTS, with excellent light absorption properties and made of abundant and environmental friendly elements, to the field of photocatalysis. |
