dc.description.abstractHighly efficient water splitting electrode based on uniform platinum (Pt) nanoparticles on self-organized TiO2 nanotube arrays (TNTAs) was prepared by a combination of multi-step electrochemical anodization with facile photoreduction process. Uniform platinum (Pt) nanoparticles with an average diameter of 8 nm are distributed homogeneously on nanoporous top layer and underneath TiO2 nanotube wall. In comparison to pristine TNTAs, Pt@TNTAs show substantially enhanced photocurrent density and the incident photon-to-current conversion efficiency (IPCE) in the entire wavelength window. The maximum photocurrent density and IPCE from the optimized Pt@TNTAs photoelectrode (Pt, similar to 1.57 wt%) were about 24.2 mA cm(-2) and 87.9% at 350 nm, which is much higher than that of the pure nanotubes sample (16.3 mA cm(-2) and 67.3%). The resultant Pt@TNTAs architecture exhibited significantly enhanced photoelectrochemical activities for solar water splitting with hydrogen evolution rate up to 495 mu mol h(-1) cm(-2) in 2 M Na2CO3 + 0.5 M ethylene glycol under the optimal external bias of -0.3 V-SCE.
