The present invention relates to a catalyst for hydrogen generation reaction which primarily plates a Ni-Cu alloy layer on a carbon substrate and then secondary plates the nickel-based catalyst thereon to increase a reaction surface area due to a rough surface of the Ni-Cu alloy layer, wherein the Ni-Cu alloy layer serves as a nucleus to improve adhesion between the nickel-based catalyst material and the substrate, thereby improving hydrogen generation activity and lifespan. 본 발명은 카본 기판 위에 Ni-Cu 합금층을 1차 도금한 후 그 위에 니켈 기반 촉매를 2차 도금함으로써, 상기 Ni-Cu 합금층의 거친 표면으로 인해 반응 표면적이 증가되며, 상기 Ni-Cu 합금층이 핵의 역할을 하여 니켈 기반 촉매 물질과 기판 사이의 접착성이 향상되어 수소 발생 활성도와 수명을 향상시킬 수 있는 수소발생 반응용 촉매에 관한 것이다.
