To develop the efficient photocatalytic hydrogen production device, tin monosulfide (SnS) quantum dots (QDs) were deposited onto a nanoporous TiO2 electrode by the successive ionic layer adsorption and reaction (SILAR) method. When Pt nanoparticles as co-catalysts were modified at the interface between the electroconductive glass substrate and nanoporous SnS QD(S)/TiO2 layer, hydrogen molecules were produced under visible-light irradiation without applying a bias potential. In addition, the size and color of SnS QDs could be tailored using SILAR method, and the optimal structure of the SnS QDs was determined for efficient photocurrent generation and hydrogen production. The photocatalysis device developed in the present study was constructed as a simple single plate consisting of non-toxic elements. (C) 2015 Elsevier B.V. All rights reserved.
