Zusammenfassung:The present invention relates to a method for manufacturing a nano-porous metal structure by an electrophoretic deposition method, which comprises: a first step of preparing a precursor solution by mixing a polymer, a metal precursor, and a solvent; a second step of preparing a colloidal solution by adding a reducing agent to the precursor solution and enabling a metal ion in the precursor solution to be colloidal; a third step of immersing an FTO transparent substrate in the colloidal solution and then, depositing a polymer and a metal particle on an electrode through an electrophoretic deposition method; and a fourth step of heat treating the polymer at 300-600°C to burn out the polymer. 본 발명은 전기영동 증착법을 이용한 나노 다공성 금속구조체의 제조방법에 관한 것으로, 폴리머, 금속 전구체 및 용매를 혼합하여 전구체용액을 준비하는 제1단계; 상기 전구체 용액에 환원제를 투입하고 전구체용액 내의 금속 이온을 콜로이드화 시켜 콜로이드 용액을 제조하는 제2단계; 상기 콜로이드 용액에 FTO 투명기판을 침지한 후, 전기영동 증착법을 통해 상기 전극에 폴리머 및 금속 입자를 증착시키는 제3단계; 및 상기 폴리머가 연소(burn out)되도록 300 내지 600℃에서 열처리하는 제4단계;를 포함하는 것을 기술적 특징으로 한다.
