제목 Synthesis of Highly Ordered Mesoporous Silver Catalyst and Pre-treatment Effect on CO Oxidation
초록 Highly ordered mesoporous silver material was successfully synthesized from a mesoporous silica template (KIT-6) with 3-d channel structure using the nano-replication method.The effects of H2 or O2 pretreatments on the catalytic performance of the mesoporous silver were investigated using a temperature programmed CO oxidation technique in a fixed bed reactor.The mesoporous silver material that was pretreated with H2 exhibited an excellent catalytic activity compared to the as-prepared and O2-treated catalysts.For the CO oxidation, the apparent activation energy of the H2-treated mesoporous silver catalyst was 61 +/- 0.5 kJ mol-1, which was also much lower than the as-prepared (132 +/- 1.5 kJ mol-1) and O2-treated catalysts (124 +/- 1.4 kJ mol-1). Moreover, this present mesoporous silver material showed good catalytic stability.
