Abstract

The application relates to the technical field of textile dyeing and finishing, and particularly discloses a foam nickel loaded nitrogen-doped carbon nanotube / Mn-Zn-P alloy composite material, a preparation method and application thereof. The preparation method is as follows: a calcium carbonate / Ni-Fe alloy layer is prepared on the surface of foam nickel; then, an organic alcohol amine and an alkyne substance are used as a nitrogen source and a carbon source to pre-deposit a nitrogen-containing carbon layer, and subsequently, N2-NH3 and N2-ethylene mixed gas is sequentially introduced to carry out stage-by-stage chemical vapor deposition, so that a Ni / nitrogen-doped carbon nanotube array is obtained; finally, Mn-Zn-P alloy particles are loaded through constant-current electrodeposition. The composite material prepared by the application has high conductivity, excellent corrosion resistance and cycle stability, and provides an ideal electrode material for electrocatalytic hydrogenation reduction, and can be directly used as an indigo reduction electrocatalytic electrode, so that the application has wide industrial application prospects in the field of blue jean dyeing.
