Abstract

The invention particularly relates to a porous titanium nitride nanotube array film and a preparation method thereof. The technical scheme of the method is that: first, a polished and buffed titaniferous metal sheet is used as an anode to be put into electrolyte for carrying out anodic oxidation, the voltage of anodic oxidation is 10-60 V, and the time of anodic oxidation is 0.5-5 hours; then the titaniferous metal sheet after anodic oxidation is washed and dried, and the dried titaniferous metal sheet is subjected to annealing treatment at the temperature of 300 to 600 DEG C in the air; finally the titaniferous metal sheet after the annealing treatment is subjected to annealing at the temperature of 300 to 600 DEG C in the atmosphere that the volume of a nitrogenous precursor is 10-100 percent at a speed of 1-20 DEG C / min, and is cooled along a furnace; and the titanium nitride nanotube array film is obtained on the surface of the titaniferous metal sheet. The preparation method disclosed by the invention is simple, and the process is reliable. The prepared porous titanium nitride nanotube array film is uniformly distributed with nanometer-size holes from a tube mouth to a tube bottom, and the size of the holes can be adjusted. The porous titanium nitride nanotube array film is suitable for the field of electrochemistry.

Description

technical field [0001] The invention belongs to the technical field of nanocomposite structures. Specifically relates to a porous titanium nitride nanotube array film and a preparation method thereof. technical background [0002] In recent years, nanomaterials have attracted widespread attention due to their great scientific value and potential application value. Theoretical and experimental studies have shown that nanostructures exhibit superior properties compared to bulk materials. In particular, one-dimensional nanomaterials (such as nanowires and nanotubes) have one-dimensional electron conduction channels, thus exhibiting excellent photoelectrochemical properties. TiN is a good metalloid substance, due to its good electrical conductivity and wear resistance, stable physical and chemical properties, low cost and non-toxic characteristics, and TiN has a similar electronic layer structure to noble metals such as Pt [E. Furimsky , Appl. Catal. A 2003, 240, 1.[20] Q.W. ...
