Recent advances in non-thermal plasma (NTP) catalysis towards C1 chemistry

Structural effect of Ni/TiO2 on CO methanation: improved activity and enhanced stability

“…Shinde and Madras 25 performed a sonochemical treatment of a Ni/TiO 2 catalyst precursor and got a highly active and stable CO methanation catalyst. The low temperature plasma decomposition 26–28 of a nickel precursor was also found by our group 4,29,30 and others 12,18,19,31 to be an effective method of making a Ni catalyst with a strong Ni–support interaction, high dispersion and improved activity and excellent carbon resistance for CO methanation. The oxide support is important to achieve a strong Ni–support interaction with small catalyst size.…”

Introducing Methane Activation

“…Plasma-assisted methane conversion has been suggested as a promising solution to solve most of the issues that existed in thermal processes [79][80][81][82]. High-energy plasma electrons collide against neutral methane molecules to produce ions, radicals, and excited species.…”

Dielectric Barrier Discharge Plasma-Assisted Catalytic CO2 Hydrogenation: Synergy of Catalyst and Plasma

“…However, major concerns regarding CO 2 capture and storage lie in separation efficiency, operation costs, and long-term stability [4,5]. In comparison, transformation of cheap and abundant CO 2 to value-added products (e.g., CH 4 , CH 3 OH, C 2 -C 4 hydrocarbons) via hydrogenation has drawn tremendous attentions [1,[6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. In some works, CO 2 splitting (dissociation) and reversed water-gas shift (RWGS) are considered a kind of hydrogenation process; however, a reaction involving both C-O bond breaking and C-H bond formation will be mainly covered in this review, such as methanation (Equation ( 1)) and methanol production (Equation ( 2)).…”

“…While in the production of CH 3 OH, the combination of DBD plasma and CuO/ZnO/Al 2 O 3 , the optimal reaction temperature was lowered by 120 • C compared with the catalyst only approach [26]. Several reviews have been reported in plasma-assisted catalytic CO 2 conversions [1,2,[6][7][8]29,38,39]; however, a comprehensive and in-depth summary is rarely seen regarding the synergistic effects of catalyst-DBD plasma hybrid system on the catalytic performances and energy efficiency of CO 2 hydrogenation. In the following sections, an overview of the plasma (particularly DBD plasma) and a detailed description of the synergy will be provided in terms of structureperformance relationships.…”
