摘要：

A platinum (Pt) nanoparticle-covered titania (TiO2) nanotube arrays titanium (Ti) mesh electrode (Pt/TiO2-NTs/Ti) has been successfully fabricated on Ti mesh via a thermal reduction technique by spraying H2PtCl6 center dot 6H(2)O isopropanol solution onto vertically oriented TiO2 nanotube arrays. Electrochemical impedance spectroscopy (EIS) and cyclic voltammerty (CV) investigations showed that the Pt/TiO2-NTs/Ti mesh electrode has superior electrocatalytic activity, good stability, and low ohmic series resistance (3.41 Omega cm(2)). With the diamond-shaped holes, the actual area of the Ti mesh electrode was less than that of the Pt/FTO glass electrode, but the catalytic activities were essentially equal. A flexible dye-sensitized solar cell was assembled from the Pt/TiO2-NTs/Ti mesh electrode and a sensitized TiO2 photoanode on Ti foil substrate, and it reached a power conversion efficiency (PCE) of 5.6% using a backside illumination simulated solar light (AM 1.5G, 100 mW cm(-2)).
