CO2 methanation on Ru/TiO2 catalysts: On the effect of mixing anatase and rutile TiO2 supports

Noble-metal-free and Pt nanoparticles-loaded, mesoporous oxides as efficient catalysts for CO2 hydrogenation and dry reforming with methane

“…The produced SNG is easy to store and can be transported in existing natural gas pipelines. A variety of transition metals such as Ni [44][45][46], Co [47][48][49], Pd [50,51], Ru [52][53][54], Rh [55,56] have been widely investigated as active components for CO 2 methanation.…”

“…Among these metals, Ni and Co are promising candidates due to its lower cost than Pd, Ru, and Rh. A variety of oxide supports have been used for the CO 2 methanation that includes Al 2 O 3 [57][58][59], SiO 2 [47,60,61], TiO 2 [52,53,62,63], CeO 2 [50,61,64], NiO [65], Co 3 O 4 [66].…”

NaAlO2‐Promoted Mesoporous Catalysts for Room temperature Knoevenagel Condensation Reaction

“…This clearly demonstrated that, active species are well dispersed in the silica materials or that the particles of sodium aluminate species are smaller than the detection limit (∼5 nm). Three peaks around 2θ=25.4, 48, and 55° were observed for 20 SATiO 2 , which are characteristic of anatase‐type titania . The intensity of XRD peaks of the sample reflects that the formed nanoparticles are crystalline and broad diffraction peaks indicate very small size crystallite.…”

Catalytic CO Methanation over Mesoporous ZSM5 with Different Metal Promoters

“…However, this synergistic effect needs to be further clarification in the future work. In the recent study of Kim et al [37], the high methanation activity of Ru/TiO2 catalyst have been reported, which simply governed by "synergy" interaction of Ru and TiO2 support (in anatase and rutile phase), and further led to formation of more dispersed and active Ru species. The improvement of the catalyst in term of catalytic activity with the introduction of metals onto supporting material was also reported in the previous literatures [38][39][40][41][42][43][44].…”
