Reports Outline Applied Catalysis Research Study Findings from W. Donphai and Colleagues

June 13, 2014

By a News Reporter-Staff News Editor at Science Letter -- Data detailed on Applied Catalysis Research have been presented. According to news reporting originating in Bangkok, Thailand, by NewsRx journalists, research stated, "In this research, the novel composite catalysts between nickel and carbon nanotubes (CNTs) over mesocellular silica (MS) support were synthesized with an attempt to improve their stability to deactivation due to coke deposition in dry reforming reaction. Accordingly, the MS support was primarily prepared based on the synthesis of SBA-15 mesoporous silica with 1,3,5-trimethylbenzene (TMB) as a pore expanding agent."

The news reporters obtained a quote from the research, "After that, nickel metal was loaded onto the MS support by using an incipient-wetness impregnation method, followed by CNTs synthesis via catalytic chemical vapor deposition (CCVD) technique through tip-growth mechanism. It was found that the existence of CNTs composite catalysts with nickel metal clusters on the tips of CNTs (Ni-CNTs/MS catalysts) could significantly improve the catalyst stability in dry reforming reaction (at 650 degrees C for 24h) and simultaneously inhibit reverse water-gas shift reaction compared to that of Ni/MS catalyst. After 24 h time on stream, CO2 and CH4 conversions of Ni/MS catalyst were approximately decreased by 10%, while those of Ni-CNTs/MS catalyst were increased by 3%. This outstanding performance could be attributed to selective formation of carbon by-products as the tube-length extension of the existing CNTs."

According to the news reporters, the research concluded: "Accordingly, the active surface of Ni-CNTs/MS catalysts were remained constant throughout the period of dry reforming reaction."
