건식 공정에서 금속 전구체의 자발적 환원 반응에 의해 제조된 Ni-Pt/탄소 나노 촉매의 특성|RISS 상세보기

다국어 초록 (Multilingual Abstract)

Fe-Pt/C nanocatalysts were prepared via spontaneous reduction reaction of nickel(II) acetylacetonate and platinum(II) acetylacetonate on the surface of carbon black in dry process, and their morphology and elemental analysis were characterized by scanning electron microscopy, transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy. The loading weight of the nanocatalysts was measured by thermogravimetric analysis and the surface area was measured by BET analysis. TEM observation showed that Ni and Pt nanoparticles was well dispersed on the carbon black and their average particle size was 4.21 nm. The loading weight of Ni-Pt nanocatalysts on the carbon black was 5.96-6.83 wt%, and the value increased with increasing nickel(II) acetylacetonate content. As the Ni-Pt loading weight increased, the specific surface area decreased significantly by more than 70%, because Ni-Pt nanoparticles block the micropores of carbon black. I-V characteristics showed that water electrolysis performance increased with increasing Pt nanocatalyst content.
