Due to its small particles and large specific surface area, nano titanium nitride can be dispersed in other materials to form a conductive network, which greatly improves the conductive performance of the composite material. Therefore, nano-titanium nitride is a material with broad application prospects. Among them, the applications of nano-titanium nitride TIN in electrochemistry are as follows:
1) Application in fuel cell
① Nano TiN as the electrode catalyst carrier material
Nano titanium nitride TiN is used as the carrier material of the fuel cell electrode. Through the synergistic effect with platinum Pt, it not only improves the electro-oxidation ability of the anode to methanol and other organic fuels, but also improves the electro-reduction catalytic performance of the cathode to oxygen. The corrosion resistance and long-term stability of the electrode are greatly enhanced, and the performance of the fuel cell is greatly improved.
②The application of nano-TiN in bipolar plate materials
Generally, metal materials that can be used as electrode plates include Ti, Al, and stainless steel. The disadvantage of using metal electrode plates is that their corrosion resistance is relatively poor and cannot meet the long-term stability of fuel cells. TiN has high electrical conductivity, corrosion resistance, oxidation resistance and excellent mechanical properties. It is very suitable for composite modification of metals such as Ti, Al and stainless steel to improve the corrosion resistance and electrical conductivity of the bipolar plate.
2) Application in supercapacitors
Various nanostructured TiN with excellent electronic conductivity and high specific surface area, such as nanotube arrays, nanowires, nanorods and core-shell structures, can well improve the capacitance performance and cycle stability of supercapacitors.
3) Application in lithium-ion batteries
As the electrode carrier material of lithium ion batteries, TiN can not only improve the conductivity of the electrode, but also greatly increase the diffusion coefficient of lithium ions, thereby improving the capacity, rate and stability of the battery, showing its broadness in lithium ion batteries. Application prospects.
