This invention relates to a method for preparing and applying a self-supporting amorphous metal-coated nickel pyrite electrode, belonging to the field of electrocatalytic materials technology. It employs a multi-scale synthesis strategy to grow a nickel-iron metal-organic framework in situ on a nickel-iron foam substrate, followed by chemical vapor deposition (CVD). This process successfully constructs a self-supporting nickel pyrite electrode covered with an amorphous layer rich in metal clusters. This unique crystalline-amorphous integrated system forms a synergistic structure consisting of a stable conductive core, a dynamically active shell, and an interfacial strain region. The amorphous region exposes more highly active sites and serves as an ideal reconstruction precursor, thereby accelerating the formation of the active phase. Simultaneously, the crystalline core acts as a stable conductive framework, providing mechanical support and efficient electron injection for the surface active layer, kinetically limiting the reconstruction depth. This dual function prevents excessive oxidative dissolution of the catalyst, achieving a dual breakthrough in dynamic stability and catalytic performance.
