摘要

In this paper, we report a novel electrode of 3D ordered CdS/CdSe co-sensitized sea urchin-like SnO _(2) /TiO _(2) nanotube arrays for photoelectrochemical hydrogen production. This novel photoanode presents excellent PEC performance, yielding a maximum photocurrent density of ~6 mA cm ~(?2) at 1.4 V vs. RHE under light illumination AM 1.5 (100 mW cm ~(?2) ), which is due to the 3D structural effect of the SnO _(2) /TiO _(2) sea urchin nanotubes, stepwise cascade band alignment between SnO _(2) /TiO _(2) and CdS/CdSe as well as the improvement of light harvesting in the visible region.
