Description

technical field [0001] The invention relates to the technical field of nanocomposite structures, in particular to a method for preparing a titanium nitride niobium nanotube array. Background technique [0002] In the field of electrochemical production and research, precious metals such as Pt, Pd, and Ru have incomparable advantages in the application of functional electrodes such as hydrogen evolution, oxygen evolution, chlorine evolution, electrocatalysis, photoelectrocatalysis, and inert electrodes. However, precious metals are scarce on earth, expensive, and easily poisoned and deactivated by underpotential deposition. In order to improve the utilization rate of noble metals and reduce costs, noble metals need to be highly dispersed, so noble metals are often loaded on some catalyst supports. The catalyst carrier needs to meet the following requirements: (1) have good electrical conductivity to provide electron channels; (2) have a large specific surface area to achieve...
