(ZnS)(0.4)(AgInS2)(0.6) nanocrystals (NCs) capped by S2- ions exhibit interesting electronic properties, absorbing visible light along with a suitable band alignment as well as properties such as high surface area providing active reaction sites for photocatalytic H-2 evolution. A high activity of 5.0 mmol g(-1) h(-1) is achieved using non-toxic (ZnS)(0.4)-(AgInS2)(0.6) NCs as photocatalysts without the need for a noble metal co-catalyst.
