“…The peaks are sharper than CT-2 and CT-3 due to the crystallinity of MgO forming NiO-MgO solid solution. Peaks are due to the effective replacement of Mg2+ by Ni2+ during impregnation [13]. The addition of ZrO2 as support generated further peaks at 2θ = 30.2°, 35.3°, 50.4° and 60.1° as evidenced in figure 1 for CT-2 and CT-3.…”

This study intended to evaluate the catalytic activity of Ni/MgO-ZrO2 to produce syngas through dry reforming of methane (DRM). The catalyst was prepared by using co-precipitation method followed by impregnation of Ni metal. XRD, BET and FESEM were used to analyze the physicochemical characteristics of the prepared catalyst. A stainless steel vertical reactor fixed with a catalyst bed inside was used to run the DRM process at 800°C, 1 atm and 1:1:1 ratio of CO2:CH4:N2. From the three catalysts studied, Ni/MgO-15%ZrO2 had the maximum conversion for CH4 and CO2 compared to the other two catalysts. The high conversion achieved was because of zirconium oxide. The result obtained from the DRM reaction was further supported by the characterization results, which included average particle size, the morphology of the catalyst, and catalyst peaks.

“…Lu et al 4 demonstrated that proper V-doping improved the dispersion and surface electron cloud density of Ni NPs in LDH-derived Ni x -V-MgAl catalysts, resulting in the conversions of CO 2 and CH 4 above 90% during an 80 hour test. Al-Fatesh et al 24 confirmed that the Ni-SBA-15 catalyst doped with 0.5% Sc consistently maintained the conversions of CH 4 and CO 2 by around 78% and 86%, respectively, and a H 2 /CO ratio of up to 0.99 during the 80 hour stability testing. Zhang et al 25 proved that Mo doping realized the MoO x ↔ MoC x O y redox cycle in the bimetallic Mo–Ni catalyst, which inhibited the oxidation of Ni, and improved the activity of the Ni catalyst and the ability to resist carbon deposition.…”

Dry reforming of methane (DRM) is an established process that utilizes CH4 and CO2 to produce syngas, which is subsequently used to produce liquid fuel. Developing an optimized catalyst with favorable physicochemical properties is essential to enhance the effectiveness of the DRM process. In this study, we report novel findings on Ni/ZrO2 + Al2O3 catalyst performance promoted with strontium (Sr) for DRM reaction. The characteristics of fresh and spent catalysts were evaluated via a suite of analytical characterization techniques, including physisorption analysis, temperature‐programmed reduction, transmission electron microscopy, X‐ray diffractometry, Raman spectroscopy, temperature‐programmed desorption, temperature‐programmed oxidation, and thermogravimetric analysis before actual DRM performance analysis. The integration of Sr essentially enhanced the basicity, imparted CO2 adsorption stability, and improved the reducibility of the catalyst. An optimal concentration of 3.0 wt% Sr promoted on the catalyst afforded the highest CH4 and CO2 conversions. The work presented in this contribution affords an understanding of optimum Sr loading and provides insights into the synergistic role of Sr on catalytic performances as applied to the DRM process.
