In this study, Fe-Ni bimetallic catalyst supported on kaolin is prepared by a wet impregnation method. The effects of mass of kaolin support, pre-calcination time, pre-calcination temperature and stirring speed on catalyst yields are examined. Then, the optimal supported Fe-Ni catalyst is utilised to produce multi-walled carbon nanotubes (MWCNTs) using catalytic chemical vapour deposition (CCVD) method. The catalysts and MWCNTs prepared using the optimal conditions are characterized using high...

Nitrogen (N)-doped ordered mesoporous carbons (OMCs) with a dual transition metal system were synthesized as non-Pt catalysts for the ORR. The highly nitrogen doped OMCs were prepared by the precursor of ionic liquid (3-methyl-1-butylpyridine dicyanamide) for N/C species and a mesoporous silica template for the physical structure. Mostly, N-doped carbons are promoted by a single transition metal to improve catalytic activity for ORR in PEMFCs. In this study, our N-doped mesoporous carbons were...

Materials with appropriate surface roughness and low surface energy can form superhydrophobic surfaces, displaying water contact angles greater than 150°. Superhydrophobic carbon-based materials are particularly interesting due to their exceptional physicochemical properties. This review discusses the various techniques used to produce superhydrophobic carbon-based materials such as carbon fibers, carbon nanotubes, graphene, amorphous carbons, etc. Recent advances in emerging fields such as...

the Ministry of Environment (MOE) resulted to the construction of pilot facilities termed Best Management Practices (BMPs). Twelve BMPs installed for the diffuse pollution management in the Kyung-An Stream were monitored since 2006. Data on the mass loading, removal efficiency, maintenance activities, etc. were gathered and utilized to conduct the evaluation of long-term performance of BMPs. The financial data such as actual construction, design and maintenance cost were also collected to evalua...

본 연구에서는 고속도로 강우유출수 처리목적의 우드칩 충진 침투도랑 모니터링 연구를 통하여 설계 적정성 및 성능을 평가하 였다. 강우시 모니터링 자료를 바탕으로 침투도랑의 평균 저감효율을 산정한 결과 TSS 88%, COD 94%, BOD 85%, TN 80%, TP 75%이었으며 강우조건 및 설계가 다르므로 국내외 다른 연구결과와 직접적인 비교는 어렵지만 개략적으로 유사한 저감성능을 보였다. 침투도랑의 가장 중요한 설계인자인 침투속도를 산출한 결과 강우강도가 증가함 따라 침투속도도 증가하 였으며 평균 침투속도는 40mm/hr, 도랑 내부의...

In this research, the environmental effects of rain garden when applied to a stormwater runoff originated from a rooftop were evaluated. The rain garden that was utilized as LID represents less than 1% of the catchment area that it drains. Storm event monitoring was conducted from March 2012 to August 2014 on a total of 19 storm events. In the 19 storm events that was monitored only 32% produced an outflow which has a mean rainfall characteristic of approximately 25 mm. With the application of...

도시유역에서 강우시에 발생되는 합류식 하수관거 월류수(CSOs; Combined Sewer Overflows)을 처리하기 위해 물리화학적 처리기법을 적용한 실증규모의 응집침전시스템을 개발하였다. 이에 앞서 응집침전시스템은 lab-test를 통해 도출된 최적의 설계조건이 실증규모로 증설할 시에 설계인자가 제대로 반영되었는지 평가가 필요하며, 최적조건에 따라 설계에 반영하 였다 하더라도 대상원수의 유입특성에 따라서도 처리결과에 대한 평가가 다를 수가 있다. 이에 본 연구에서는 청주하수 처리장에 유입되는 CSOs를 대상으로 각각 1m3/일과...
