3D ordered mesoporous Fe-KIT-6 catalysts for methylcyclopentane (MCP) conversion and carbon dioxide (CO2) hydrogenation for energy and environmental applications

Fibrous silica mesoporous ZSM-5 for carbon monoxide methanation

“…Another band at 550 cm -1 is corresponded to the double five-membered rings of the MFI-type ZSM-5 structure [23]. A band at 450 cm -1 is associated to Si-O-Si bending in the framework [24].…”

Supported Catalysts for CO2 Methanation: A Review

“…They tested a mesoporous-supported iron catalyst, Fe-KIT-6, synthesized for the first time with high iron loading. The high density of the iron sites strongly improves the CO 2 methanation selectivity of the catalyst at high temperatures [196]. However, it is well known that the activity and selectivity of iron catalysts are a function not only of the iron loading but also of the oxidation state of iron atoms.…”

“…Recently, Merkache et al published a scientific work in which the activity of iron catalyst in the CO 2 hydrogenation was reported [196]. They tested a mesoporous-supported iron catalyst, Fe-KIT-6, synthesized for the first time with high iron loading.…”

Preparation of Ni based mesoporous Al2O3 catalyst with enhanced CO2 methanation performance

“…In addition, mesoporous molecular sieves possessing large surface area and ordered mesoporous channel have been developed widely to optimize CO 2 methanation performance. [24][25][26] However, the silica based zeolites occur easily the collapse of mesoporous structures because of their intrinsic nature of the hydrothermal instability. As a result, designing mesoporous materials with high dispersion of Ni nanoparticles and excellent thermal stability is necessary for CO 2 methanation.…”
