n-Docane의 선택적 탈수소화를 위한 포접된 메조세공 실리카

초록

Bi-metallic PtSn nanoparticles encapsnlated in mesoporous SBA-16 were sucessfully prepared by the simple implegantion methods followed by thermal and microwaves drying. X-ray diffraction(XRD) and Transmission electron microscopy (TEM) image clearly showed the Bi-metallic nanoparticles were more well dispersed in the mesoporous cubic pore by volumetic drying than thermal one. And we also found that PtSn nanopartilces obtained by etching of silics wall with HF were narrowly distributed on size distribution of 3-5min which is accorded with the pore size limitation of cage-like pore diameter of SBA-16. Moreover, bi-metallic catalyst encapulated mesoprous silica has the high catalytic activity for the dehydrogenation of n-dodecane.
