초록

본 연구에서는 악취가스 및 휘발성 유기 화합물을 산화 제거하기 위한 백금/티타니아를 허니컴 및 메탈폼 담체에 코팅하는 방법을 확인하였다. 다양한 방법 중 파우더 코팅과 나노 코팅에 대한 비교를 수행하였다. SEM/EDX (Scanning Electron Microscopy/Energy Dispersive X-ray spectroscopy) 분석은 허니컴 및 메탈폼의 표면 상태 및 노출된 백금 성분비를 조사하는데 사용되었다. 또한, 촉매 코팅 방법에 따른 톨루엔, 트리메틸아민, 아이소프로필 알코올의 제거 성능을 비교하였다.

In this study, different methods to coat honeycomb and metal foam substrate with platinum/titania for removing odor gases and volatile organic compounds were investigated. Among them, the powder coating and the nano coating were compared. Scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDX) analysis was used to investigate the surface conditions and exposed platinum composition ratios on honeycomb and metal foam. Also, the catalytic oxidation performance of toluene, trimethylamine and isopropyl alcohol was compared according to the coating method.
