| titleOfInvention | Surface roughening method for improving catalytic performance of nickel-titanium alloy |
| abstract | The invention relates to the field of electrode material treatment methods, in particular to a surface roughening method for improving the catalytic performance of nickel-titanium alloy. The method comprises the following steps: after the flat nickel-titanium alloy is pretreated, the flat nickel-titanium alloy is subjected to metallographic phase polishing and roughing treatment and subsequent dealloying treatment; the metallographic polishing and roughening treatment is sand paper polishing treatment; the abrasive paper polishing treatment at least selects 2 kinds of abrasive paper with different meshes for polishing at least once, and the mesh number of the abrasive paper used for polishing for the (N + 1) th time is not less than that of the abrasive paper used for polishing for the nth time. The dealloying treatment is a corrosion treatment of hydrofluoric acid (HF) solution, a part of titanium elements are removed, and active sites are exposed. The treatment method is simple and efficient, and is suitable for industrial treatment; the treatment cost is low; the electro-catalytic oxidation performance of the nickel-titanium alloy to methanol can be effectively improved by roughening the surface of the material. |
