The depiction of the preparation process of Bi2S3 NWs/TiO2 NRs and SEM images of samples for each step are shown in Figs. 1 and 2, respectively. First, TiO2 NRs directly grown on FTO substrates were obtained via a simple hydrothermal process. The SEM images of TiO2 NRs shown in Fig. 2a, b reveal that TiO2 NRs are smooth and their average length is about 1.5 μm. Second, the BiVO4 layer was covered on the surface of TiO2 NRs by a simply soaking and annealing treatment process. As shown in Fig. 2

In this paper, we demonstrate a novel heterogeneous nanostructure by grafting the Bi2S3 nanowires (NWs) on TiO2 nanorod arrays (NRs) and the prepared films as photoanodes show an excellent photoelectrochemical (PEC) hydrogen generation performance. The hydrogen evolution rate is 35.97 μmol cm-2 h-1 at a potential of 0.676 V vs. RHE (-0.2 V vs. Ag/AgCl) under visible light illumination. Importantly, the growth mechanism of such a heterogeneous nanostructure is put forward firstly and the intrinsic nature of Bi2S3 crystal structure is the main r...
