“…Above 350°C, carbonyl and formyl species were further hydrogenated onto Ni 0 particles to form probably formaldehydes, methoxy species and, finally, methane. The mechanism proposed by Westermann et al [50] is indeed in accordance with some suggested pathways also found in the literature, [55,56] where both formates and CO could act as intermediate species for CO 2 methanation reaction, and contrary to those which considered that only CO (mainly over monometallic catalysts) [42,[57][58][59][60][61][62][63] or formate species (mainly over bimetallic catalysts) [64][65][66][67][68][69][70][71] could be the true intermediates in this reaction. Additionally, Westermann et al [54] also proposed that by adding Ce to Ni/zeolites (Ce/Ni/USY) the bifunctional mechanism suggested in the literature without CO as intermediate species [64][65][66][67][68][69][70][71] is favoured.…”

This work provides a short review of the literature concerning the utilization of zeolites as supports for CO2 methanation catalysts. Indeed, the application of these materials in carbon dioxide hydrogenation into methane has led to considerably relevant performances according to the literature, being zeolite‐based catalysts more active and selective than commercial materials reported. Considering the well‐known zeolite features and the possibility to finely modulate its properties, inducing relevant changes on the adsorbed metal species and in the CO2 activation ability of the catalyst, potentially interesting catalytic properties can be generated also towards this transformation. Possible correlations between the characteristics of these materials, found as relevant for CO2 methanation, and the catalytic properties will be then presented and discussed.

a] InÞsG raÅa, [b] JosØ M. Lopes, [a] andC arlosH enriques* [a] Introduction CO 2 methanation, as af orm of alleviating CO 2 emissions, has been the focus of much attention in the last few years, with thermal, photocatalytic,e lectrochemical, or even plasma assisted processes being used. [1][2][3][4][5][6] Ni and Ru-based materials have been commonly used for this reaction, on different supports, such as Al 2 O 3 , [7][8][9][10][11][12][13][14][15] SiO 2 , [16][17][18][19][20] Ce and Zr oxides, [21][22][23][24][25][26][27][28] hydrotalcites and hydrotalcite-derived materials, [21,[29][30][31][32] carbon nanotubes, [33][34][35][36][37] mesoporous materials, [38][39][40][41][42][43] and zeolites. [44][45][46][47][48][49] Amongt he different supports used, zeolitesh ave been revealed to be interesting materials, as their properties (e.g.,S i/ Al ratio, compensating cation) can be easily modified to meet the requirements of the reaction.Ni-basedu ltrastable Yz eolites (USY) have been appliedt o the CO 2 methanation reaction, with very promising results. [44][45][46][47][48][49] In these studies, changes to the metal incorporation method (impregnation or ion-exchange), the preparation conditions, the type of compensating cation, and the Si/Al ratio have been investigated to try to obtain an optimized catalyst formulation. [44][45][46] In addition, some highlights into the mechanism and [a] M.

“…So far, few works have been published dealing with the use of micro and mesoporous materials as supports for Ni-based CO2 and CO methanation catalysts [6][7][8][9][10][11][12][13][14][15][16][17] , the mainly used being USY zeolite, SBA-15 and MCM-41. Ni-based USY zeolite catalysts showed interesting performances towards methanation being reported the effect of Ni content, Ce addition, the preparation method conditions and some highlights concerning the reaction mechanism 6,[17][18][19] .…”

All the results are comparable to the obtained using a HNaUSY zeolite with Si/Al=2.8 as support. Cerium incorporation on Ni/mesoporous supports allowed enhancing the CO2 conversion, especially at lower temperatures, as already reported for the zeolite-based samples.
