Design of functional electrode structures and their characterization towards reduction of supported noble metals

本工作中，我们在含氟电解液中通过阳极氧化法制备了不同直径和长度的TiO_2纳米管阵列，并在其上沉积了多种贵金属纳米颗粒，对其性能进行了表征。结果表明，在TiO_2纳米管阵列上高度分散的铂纳米粒子可以提高甲醇的电氧化性能。银纳米颗粒的分散增强了光生电流，即使在钌染料吸附在纳米管阵列上的量很小的情况下。

In the present work we fabricated TiO_2 nantotube arrays with a wide range of diameters and lengths by anodization in fluoride containing electrolytes, deposited nanoparticles of various noble metals on the TiO_2 nanotube arrays and characterized their properties. It becomes clear that the highly dispersed platinum nanoparticles on TiO_2 nanotube arrays can improve the electro-oxidation of methanol. The dispersion of Ag nanoparticle enhances photo-induced current even in case the amount of ruthenium dye adsorbed on nanotube arrays is small.
