Summary:The invention provides a method for preparing a Ni-Fe-P-MnFeO3 electrocatalyst through an electrochemical method. The method is characterized in that a matrix is a metal iron sheet or stainless steelor graphite subjected to activation pretreatment; from composition, a plating solution comprises 100-300g.L<-1> of NiSO4.6H2O, 5-80g.L<-1> of NiCl2.6H2O, 5-80g.L<-1> of FeSO4.7H2O, 5-70g.L<-1> of H3BO3 and 2-50g.L<-1> of Na3PO4.12H2O; 10-100g.L<-1> of MnFeO3 is added into the electroplating solution; an electrodeposition current density is 10-300mA/cm ; the temperature of the plating solution is0-20 DEG C; an electrodeposition time is 0.1-5h; and the obtained Ni-Fe-P-MnFeO3 plated layer is an amorphous plated layer. A catalytic hydrogen production electrode has the characteristics of beingsimple and convenient in preparation process, high in stability, capable of effectively reducing hydrogen evolution overpotential, and high in electrocatalytic activity; and moreover, use for noble metal salts and a strong reduct
