Dry reforming of methane (DRM) bears great hope for the catalytic community as well as environmentalists for its potential to convert two greenhouse gases, CH4 and CO2, together into synthetic feedstock “syngas”. The stable tetragonal zirconium yttrium oxide phase over the “Yttria‐zirconia supported Ni” catalyst (Ni/YZr) brings >70% CH4 conversion against 50% CH4 conversion over zirconia supported Ni catalyst) in 7 h time‐on‐stream (TOS). The use of the second metal oxide (MOx; M = Ho, Ga, Gd, Ba, Cs) in a small amount (4 wt%) over Ni/YZ catalyst is found to promote the catalytic activity further. Herein, we have prepared such metal‐promoted yttria‐zirconia supported Ni catalyst, employed them for DRM and characterized them with surface area porosity, X‐ray diffraction, spectroscopic techniques, temperature programmed techniques and transmission electron microscopy. A fine correlation of characterization results with catalytic activity brings out various useful information that would be useful for establishing yttria‐zirconia supported Ni catalyst for DRM. Ni stabilized over cubic zirconium holmium oxide phase in 5Ni4Ho/YZr catalyst, cubic zirconium gadolinium oxide phase in 5Ni4Gd/YZr catalyst and cubic zirconium barium oxide phase in 5Ni4Ba/YZr catalyst perform excellent toward DRM. Catalytically, 5Ni4Ho/YZr catalyst achieves CH4 conversion as high as ~85% whereas 5Ni4Ba/YZr and 5Ni4Gd/YZr show CH4 conversions of about ~80%. Even in 30 h TOS study, 5Ni4Ho/YZr catalyst showed >81% CH4 conversion with retaining highest H2/CO (0.97).

The complex catalyst synthesis procedure is always a hurdle in the industrialization of catalysts. Industry eagerly needs catalysts for the dry reforming of methane, which can be prepared through straightforward, cheap processes by semi-skilled workers. Herein, dual metal oxide support 10 wt% MOx (M = Ti, Si, Zr, Y) & 90 wt% Al2O3 is prepared by just mixing mechanically and thereafter, catalytic active 5 wt% Ni is dispersed over the support by impregnation method. Metal oxide pairs in ZrO2 + Al2O3, TiO2-Al2O3, SiO2 + Al2O3, and Y2O3 + Al2O3 supports are non-interacting, partially-interacting, significantly interacting (through Si–O–Al) and highly interacting (with maximum covalence character) respectively. Ni dispersed over SiO2 + Al2O3 or Y2O3 + Al2O3 supports are strongly interacted, whereas Ni/Y2O3 + Al2O3 catalyst has oxide enrichment over the surface for potential oxidation of carbon deposit. The interacting nature of metal oxide pair in support, stability of active sites and extent of oxide enrichment over the surface confirms the following order of coke deposition, Ni/Y2O3 + Al2O3 (8%) < Ni/SiO2 + Al2O3 (17%) < Ni/TiO2-Al2O3 (38.2%) < Ni/ZrO2 + Al2O3 (52.3%), as well as reverse order of catalytic activity, Ni/Y2O3 + Al2O3 (60%) > Ni/SiO2 + Al2O3 (55%) > Ni/TiO2-Al2O3 (50%) > Ni/ZrO2 + Al2O3 (47%).

Utilization of CO2 as a promising oxidant under dry reforming methane (DRM) can mitigate two greenhouse gases (CO2 and CH4) together, as well as DRM reaction may be a source of H2 energy in future. The cost-effective and handy catalyst preparation procedures like mixing, drying and calcining may turn this reaction from lab to industry. In this line, herein, 5Ni/MgO and 5Ni/MgO + MOx (M = Zr, Ti, Al) catalysts were prepared, investigated for DRM and characterized by X-ray diffraction, Raman, temperature programmed reduction/desorption, thermogravimetry and transmission electron microscope. Among the prepared catalysts, the 5Ni/MgO + TiO2 catalyst exhibits the highest concentration of active Ni sites enhanced reducibility under oxidizing and reducing environments, but catalytic excellency is hindered by severe graphitic-type coke deposition. On the other hand, the 5Ni/MgO + Al2O3 catalyst predominantly comprises metallic Ni resulting from the reduction of “strongly interacted NiO”, expanded surface area and the highest concentration of easily accessible active sites, contributing to its superior performance (H2 yield ~ 71% up to 430 min time on stream) under oxidizing and reducing conditions during DRM. The outstanding performance of the 5Ni/MgO + Al2O3 catalyst marks a significant stride towards the development of an industrially viable, cost-effective, and convenient catalyst system for DRM.
