TiO₂/graphene/CuSbS₂ mixed-dimensional array with high-performance photoelectrochemical properties.

ABSTRACT: The growing demands for reproducible and clean sources of power has prompted the exploitation of novel materials for solar-energy conversion; in any case, the improvement of their conversion efficiency remains a big challenge. We report a mixed-dimensional heterostructure to synchronously enhance charge separation and light-absorption of the photoanodes via the introduction of two-dimensional reduced graphene oxide and zero-dimensional CuSbS₂ quantum dots on one-dimensional TiO₂ arrays. The experimental results show that the graphene sheets with a low Fermi level and a superior electron mobility accept photo-excited electrons from TiO₂ and enable fast electron transportation; while the CuSbS₂ quantum dots promote the visible light-absorpti
