Commun. 47(14), 4138–4140 (2011) Adding Ru in 10% Ni/CeO 2-ZrO 2 increased the CO 2 methanation performance. When ruthenium acetylacetonate was used instead of ruthenium chloride as the precursor salt, the metal dispersion and catalytic activity were enhanced due to the templating effect of the precursor salt molecule.

Besides Al 2O 3-based supports, ZrO 2, CeO 2-ZrO 2 and other CeO 2-based defect-rich supports are also commonly used in NiRu-based catalysts and will be discussed thereafter. Ocampo et al. [ 106] modified 5% Ni catalysts supported on CeO 2-ZrO 2 by changing the CeO 2/ZrO 2 ratio and by adding a noble metal phase (Ru and Rh). A mass ratio between CeO 2 and ZrO 2 of 1.5 in the support led to the best results and 0.5% noble metal addition increased the catalytic activity and stability by enhancing Ni dispersion. In a later study, Shang et al. [ 107] prepared Ru-doped 30% Ni catalysts supported on CeO 2-ZrO 2 via an one-pot hydrolysis method. They found that Ru addition could enhance Ni dispersion and promote the basicity of the catalysts, thereby achieving a quite increased low-temperature activity. They reported that their best performing catalyst 3% Ru, 30% Ni/Ce 0.9Zr 0.1O 2 could achieve 98.2% CO 2 conversion and 100% CH 4 selectivity under the reaction conditions tested. Ni 3Fe provided the highest TOF CH4 out of all bimetallic catalysts and the monometallic Ni one. Linear correlation was observed between the d-density of states at the Fermi level (N EF) and TOF CH4 based on DFT calculations. All Ni 3Fe bimetallic catalysts had a higher CH 4 yield compared to the monometallic ones. The largest activity enhancement was observed for the Al 2O 3-supported catalyst.KO C H, FAN C, CHIANG P N, et al. P-nitrophenol, phenol and aniline sorption by organo-clays[J].

Lind, Adsorption Processes for Natural Gas Treatment (Engelhard Corp, USA, 2004), p. 14 Single atom alloy catalysts (SAAC) with Pt atoms dissolved into the lattice of Ni nanoparticles supported on Al 2O 3 were highly active for CO 2 methanation. A Pt/(Ni + Pt) molar ratio of 5% was optimal. Isolated Pt atoms adjacent to Ni enhanced the adsorption of intermediate CO, while weakening the C-O bond energy and thus favoured the further conversion to CH 4.

Energy 32(16), 4005–4010 (2007)As previously discussed, Pastor-Pérez et al. [ 69] prepared Fe- and Co-modified Ni catalysts supported on CeO 2-ZrO 2. While Fe modification impeded the CO 2 methanation activity, the addition of 3% Co on a 15% Ni/CeO 2-ZrO 2 catalyst enhanced the CO 2 conversion, CH 4 selectivity and the long-term stability and it allowed for the use of higher space velocities. Following that work, Pastor-Pérez et al. [ 85] also showed that such Co modified Ni catalyst could prevent coke deposition during the reaction. The catalyst was quite robust upon long-term operation tests, while the presence of methane in the feed gas did not appear to impede the catalytic activity, but instead promoted it. In contrast to other works, the addition of Co in Ni catalysts supported on defect-rich GDC support did not offer any advantages to the catalytic performance for CO 2 methanation, as reported by Frontera et al. [ 86]. Li et al. [ 32] synthesized an effective CO 2 methanation catalyst composed of NiPd alloys supported on an SBA-15 mesoporous siliceous support. There was a strong synergetic effect between the two metals, as evidenced by H 2-TPR, and this synergy led to the bimetallic NiPd catalysts exhibiting enhanced CO 2 conversion compared to the monometallic Pd and Ni catalysts. The content of Ni and Pd in the alloy was also varied and it was shown that the Ni 0.75Pd 0.25 alloy with a Ni/Pd molar ratio of three led to the best results. Co improved the catalytic performance for CO 2 methanation above 250 °C. NiCo modified catalyst had great stability after many hours and could retain high activity under increased gas space velocities. Co increased Ni dispersion and could decrease coke deposition due to its redox properties.
