Preparation of KNiMo-based catalysts by using non-thermal plasma and their catalytic performance in the synthesis of higher alcohols from syngas

Effect of KCoMoS2 Catalyst Structures on the Catalytic Performance of Higher Alcohols Synthesis via CO Hydrogenation

“…In the synthesis of higher alcohols from syngas, it is commonly accepted that the active center of MoS 2 -based catalyst is located at the edge and corners of molybdenum sulfide [22,23], instead of the basal plane of the sheet. Therefore, the exposure of more edges and corners can facilitate the efficient conversion of syngas to higher alcohols [24][25][26]. However, the traditional Co promoted K-MoS 2 catalysts usually have more stacking of MoS 2 layers with a large geometrical size, causing less exposure of the edged and angular positioned active sites.…”

Modulating Crystallization of MoS2 Nanostructures by Dimethyl Sulfoxide for Enhanced Hydrodesulfurization

“…In order to analyze the ability of Mo to activate H 2 , H 2 -TPD analysis was performed. As shown in Figure S7, the low-temperature peak before 400 °C is attributed to the chemical adsorption of H 2 on the Mo site, while the high-temperature peak after 400 °C is attributed to the spillover of H on the Mo site . Interestingly, both MoS 2 -C and MoS 2 -C-3 have significant low-temperature peaks (100–300 °C).…”

“…As shown in Figure S7, the lowtemperature peak before 400 °C is attributed to the chemical adsorption of H 2 on the Mo site, 37 while the high-temperature peak after 400 °C is attributed to the spillover of H on the Mo site. 38 Interestingly, both MoS 2 -C and MoS 2 -C-3 have significant low-temperature peaks (100−300 °C). These lowtemperature peaks correspond to the ability of Mo to activate H 2 .…”
