Abstract
Five PtSn catalysts with different PtSn particle sizes were prepared using one-pot and co-impregnation methods for n-butane dehydrogenation. The turnover frequency (TOF) of the prepared catalysts is proportional to the PtSn metal particle size, while the selectivity to n-butenes is inversely proportional to that. The PtSn(OMSO) catalyst with a worm-like pore structure has the smallest PtSn particle size and the largest metal surface area, which exhibits the highest selectivity and specific activity among five PtSn catalysts. Additionally, the PtSn(OMSO) catalyst exhibits the highest stability. PtSn particles on PtSn(OMSO) are stabilized in the pores of the worm-like structure.
