Enhanced performance and selectivity of CO2 methanation over phyllosilicate structure derived Ni-Mg/SBA-15 catalysts

Suppressing Dehydroisomerization Boosts n‐Butane Dehydrogenation with High Butadiene Selectivity

“…The negative shifts of peak positions corresponding to NH 3 strong adsorption and the decreases of the adsorbed amounts of NH 3 after MgO addition suggested that MgO poisoned strong acid sites in catalysts (Table S10). Moreover, the decrease of acid sites was further confirmed by CO 2 ‐TPD measurement, as revealed by the positive shifts of peak positions and increase of CO 2 adsorption amounts (Figure 4d and Table S11) [45–48] . Additionally, NH 3 ‐TPD measurement was performed on the spent 0.1Pt6Mg2Ga/S10 catalyst after 10 cycles (Figure S9 and Table S10).…”

Ni/CeO2 catalysts for low‐temperature CO2 methanation: Identifying effect of support morphology and oxygen vacancy

“…Furthermore, in order to highlight superiority of the catalyst in this work, the optimal Ni/W was compared with the reported catalysts (Table S1). Kawi et al 22 . prepared Ni‐Mg‐phyllosilicate structure catalysts by ammonia evaporation method, whose catalytic activity is still lower than Ni/W even at a lower space velocity.…”

Porous organic–inorganic hybrid materials for catalysis, energy and environmental applications

“…Recently in 2021 Kawi et al reported a bi-metallic system of Ni-Mg/SBA-15 to enhance the performance and selectivity of hydrogenation of CO 2 to CH 4 . 144 The incorporation of Mg in this Ni-based heterocatalyst significantly increased the weak and total basicity of the catalyst. In this work, they compared the catalytic activity of the Ni-based catalyst prepared via wetness impregnation (WI) and ammonia evaporation (AE), revealing the enhanced low-temperature activity and higher CH 4 selectivity of the Ni-Mg/SBA-15-AE catalyst.…”
