Method for preparing nanometer platinum nickel/titanium dioxide nanotube electrode by cyclic voltammeter electrodeposition

The invention discloses a method for preparing a nanometer platinum nickel/titanium dioxide nanotube electrode by cyclic voltammeter electrodeposition, and belongs to the technical field of photoelectrocatalysis. A titanium dioxide nanotube array, tidily arranged and vertically oriented, is prepared on a titanium chip by adopting an anodic oxidation method; and then, nanometer metal particles are deposited in nanotubes and on the surfaces of the nanotubes by adopting a cyclic voltammeter electrodeposition method to prepare a nanometer platinum/nickel modified titanium dioxide nanotube electrode. An electrocatalyst preparation method needs no surface active agent, stabilizing agent or functional component in deposition, is simple in process, and is uniform in nanoparticle dispersion; and the prepared electrode can obviously reduce the toxicity of catalyst and improve the electro-catalytic property of the electrode, and is wide in application prospect.
