Abstract: 본 발명은 금속 구조체를 촉매 지지체로 사용하는 촉매 모듈에 있어서, 금속 구조체와 다공성 담체 간의 부착력을 견고하게 유지시키기 위하여 금속 구조체 표면에 요철 구조를 형성한 후 다공성 물질층 또는 담체층을 형성하는 방법 및 그로부터 제조된 촉매 모듈을 제공한다.
본 발명에서 금속 구조체 표면에 형성된 요철 구조는 열 변형 계수 차로 인하여 고온 환경에 반복하여 노출되었을 때 금속 구조체 표면으로부터 다공성 담체가 탈리되는 현상을 방지한다. 따라서, 본 발명에 의해 제조된 촉매 모듈은 고온의 사용 환경에서도 촉매 활성이 안정적으로 유지되는 장점을 갖는다.-
