Claim 1:
2. A preparation method of the graphitic carbon-doped and mixed crystal-type titanium dioxide nanotube composite for electrocatalysis according to claim 1, comprising the following steps:
using the titanium substrate as an anode and a platinum sheet as a cathode in an electrolyte for anodic oxidation to obtain a titanium dioxide nanotube array/titanium substrate composite;
annealing the titanium dioxide nanotube array/titanium substrate composite to obtain a mixed crystal-type titanium dioxide nanotube/titanium substrate composite; and
impregnating the mixed crystal-type titanium dioxide nanotube/titanium substrate composite in an organic carbon source solution for a hydrothermal reaction to obtain the graphitic carbon-doped and mixed crystal-type titanium dioxide nanotube composite for electrocatalysis.
