Title: Facile preparation and improved photocatalytic H{sub 2}-production of Pt-decorated CdS/TiO{sub 2} nanorods

Graphical abstract: - Highlights: • Pt-CdS/TiO{sub 2} nanorods were firstly realized by electrospinning. • They exhibited high photocatalytic H{sub 2} production activity. • The mechanism of the high performance was discussed. - Abstract: Pt-CdS/TiO{sub 2} nanorods with different molar ratios of Cd:Ti were prepared through an electrospinning method followed by sulfidation treatment and photodeposition. The nanorod-like samples were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), photoluminescence spectra (PL), and UV–vis diffuse reflectance spectroscopy (DRS). The results indicated that the as-prepared samples exhibited wider light absorption range and lower recombination rate of photogenerated electron–hole pairs after the introduction of Pt and CdS. The photocatalysis experiments showed that Pt-modified CdS/TiO{sub 2} nanorods exhibited much higher activities than pure TiO{sub 2} in the evolution of hydrogen under simulated solar light irradiation.
