고압 균질기를 통해 합성된 이산화망간 나노입자에 의한 일산화탄소의 촉매적 산화

​

In this study, manganese dioxide (MnO2) nanoparticles were synthesized from KMnO4 and MnCl2·4H2O without any dispersing agents and oxidant via ultra-high pressure homogenization process. We investigated various physicochemical properties and CO oxidation reactions of the MnO2 nanoparticles as a function of the number of passes at 1,500 bar in a high pressure homogenizer nozzle. The observed X-ray diffraction patterns and scanning electron microscopy images revealed that the synthesized MnO2 nanoparticles had a hexagonal structure and a uniform spherical shape. It was found from the Brunauer-Emmett-Teller measurements that the pore size of the MnO2 nanoparticles ranged from 23.6 to 7.2 nm and their specific surface area ranged from 24 to 208 m2g-1. In particular, it was confirmed from the measurements of CO conversion into CO2 that CO oxidation reaction over the MnO2 nanoparticles exhibited excellent catalytic activity at low temperatures below 100℃.
