“…Concerning H2-TPR for the samples only containing Ni (Figure 4, straight lines), two main peaks attributed to NiO weakly interacting with the supports (<500ºC) and NiO strongly interacting with the supports (>500ºC) were observed 6,7,13,[39][40][41][42][43] . The first peak is the predominant in both the SBA-15 and USY zeolite, being mostly reduced during the pre-treatment.…”

It has been developed to disseminate open access research outputs, expose data about those outputs, and enable the management and persistent access to Strathclyde's intellectual output. 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.

“…A suggested solution to inhibit carbon deposition is to promote the catalyst with a metal oxide, especially CeO 2 . The latter is characterized by redox properties (Ce 4+ ↔ Ce 3+ ) that promote oxygen vacancies formation, thus enhancing the mobility of surface oxygen whose presence contributes in lowering carbon deposition on the metallic particles [4][5][6][7]. It was also reported that both metal dispersion and metal-support interaction are improved in presence of CeO 2 [5,7].…”

It was also reported that both metal dispersion and metal-support interaction are improved in presence of CeO 2 [5,7]. Moreover, the recent use of organized mesoporous silica [8] and carbon [9,10] supports to disperse the Ni active phase appears promising.…”

“…Mesoporous SBA-15 materials in particular have distinct properties (high specific surface area, uniform narrow pore size distribution, confinement effect…) known to favor metal dispersion and limit particles sintering, with consequently interesting performances in DRM [5,6].…”

“…In a Ce-free Ni/SBA-15 catalyst, Wang et al [5] reported the formation of large Ni particles resulting in heavy coke deposition whereas in presence of cerium high nickel dispersion inside the SBA-15 channels was obtained, the Ce-enriched catalyst was moreover rather stable with minor effect of the formed carbon nanotubes on the main catalytic reaction. Nevertheless, the Ce/Si atomic ratio had to be kept below 0.04 to avoid pore blocking.…”
