High Level Material Ferro Titanium 30

A preparation method of titanium-iron-nickel high hydrogen evolution active electrocatalyst, in which a precursor with an electric double-layer structure of iron-nickel basic carbonate nanosheets is uniformly grown on CFP (carbon fiber paper) by hydrothermal method, a titanium oxide film of a certain thickness is coated on the surface of the precursor, and annealed and crystallized at 400 °C in an air atmosphere; The amorphous TiO was converted into anatase type, and the precursor basic nickel iron carbonate was converted into nickel ferrate, and the TiO-NiFeO@CFP-X composite electrocatalytic material was obtained after cooling. The product prepared by the method of the present invention has the advantages of uniform coating, firmness and controllable thickness. Ferro titanium30 nickel nanosheet electrocatalysts can electrocatalyze water and hydrogen evolution at lower overpotential conditions under alkaline conditions.

1.The method of preparing high-quality hig ferro titanium 30 based on thermite reduction and vacuum induction smelting belongs to the field of preparation process of titanium-iron special alloy, especially involving a preparation method of high-titanium-iron with a titanium content of 65%~75%. The process steps are as follows: firstly, the high-temperature melt of ferrotitanium is obtained by thermite reduction method, and then the uncooled high-temperature melt is smelted by vacuum. The reducing agent of thermite reduction smelting and vacuum induction smelting is the raw materials such as composite reducing agent and compound slag system, which is smelted by using the lower ignition initiation reaction, and the metal magnesium powder is sprayed into the high-temperature melt for deep deoxidation during the smelting process, and Fe needs to be supplemented in the vacuum induction smelting stage.
