“…The Raman band at 268, 457 and 630 cm −1 is due to the tetragonal zirconia phase. 14 The variance in peak intensity at 268 cm −1 is clearly observed in all catalyst samples. Unpromoted catalyst has tetragonal zirconia phase in moderate amount.…”

“…In Ni-based catalyst system, incorporation of 9 wt.% WO 3 in ZrO 2 support caused enhanced redox property, additional CH 4 decomposition sites and stabilization of monoclinic ZrO 2 during high-temperature DRM reaction. 14 It showed 55% H 2 yield, but it decreased due to the limited re-oxidizing capability of the surface by CO 2 and shading of the catalytic active site by thermally stable carbonates. Ceria promotional addition over tungsten oxide-zirconia-supported Ni catalyst was noticed for sequential oxygen vacancy generation.…”

Hydrogen production through methane dry reforming holds the promise of lowering greenhouse gases, that is CO2 and CH4, concentrations. Herein, Ca‐, Cr‐, Ga‐ and Gd‐promoted lanthana‐zirconia–supported Ni catalysts are investigated and characterized by X‐ray diffraction, Raman, infrared and UV‐vis spectroscopy, CH4‐temperature programmed surface reaction and cyclic reduction‐desorption experiment. All promoted catalyst systems had high and constant hydrogen yield (>70%) due to pronounced reoxidation capacity of reduced ‘NiO species strongly interacted with support’ through oxygen replenishment by CO2. The presence of mixed oxide and regeneration of reduced catalyst up to optimum level through oxygen replenishment by CO2 in Gd, as well as Cr‐promoted catalyst, outperformed (80% initially) than other promotors, Ca and Ga. In the long run (440 min to 33 h), Cr‐promoted catalyst system performed better than Gd‐promoted catalyst system as H2 yield remained constant ~79% due to the smallest energy gap between valance and conduction band, Ni‐Cr interaction species for wide range CH4 decomposition and chromate species for profound carbon deposit oxidation.

“… 13 Furthermore, the addition of a promoter over supported Ni catalysts had brought about major physiochemical changes over the catalyst surface in favor of DRM. In brief, Mg incorporation added alkalinity to the catalyst system, 2 , 14 − 17 Sr boosted Lewis basicity, 18 Yb brought about a high edge of reducibilty, 19 Sc induced basicity and a metal–support interaction, 20 W stabilized the NiO phase and modified the redox behavior, 8 , 21 , 22 Ce or Y advanced lattice ion mobility together with reducibility, 23 − 39 and B or La induced carbon gasification (through B–OH species and La 2 O 2 CO 3 formation, respectively). 40 − 46 Likewise, the addition of Sm, Gd, or Mn–Al (equal proportions) optimized the Ni size and enhanced the metal–support interaction.…”

Developing cost-effective nonprecious active metal-based catalysts for syngas (H 2 /CO) production via the dry reforming of methane (DRM) for industrial applications has remained a challenge. Herein, we utilized a facile and scalable mechanochemical method to develop Ba-promoted (1–5 wt %) zirconia and yttria–zirconia-supported Ni-based DRM catalysts. BET surface area and porosity measurements, infrared, ultraviolet–visible, and Raman spectroscopy, transmission electron microscopy, and temperature-programmed cyclic (reduction–oxidation–reduction) experiments were performed to characterize and elucidate the catalytic performance of the synthesized materials. Among different catalysts tested, the inferior catalytic performance of 5Ni/Zr was attributed to the unstable monoclinic ZrO 2 support and weakly interacting NiO species whereas the 5Ni/YZr system performed better because of the stable cubic ZrO 2 phase and stronger metal–support interaction. It is established that the addition of Ba to the catalysts improves the oxygen-endowing capacity and stabilization of the cubic ZrO 2 and BaZrO 3 phases. Among the Ba-promoted catalysts, owing to the optimal active metal particle size and excess ionic CO 3 2– species, the 5Ni4Ba/YZr catalyst demonstrated a high, stable H 2 yield (i.e., 79% with a 0.94 H 2 /CO ratio) for up to 7 h of time on stream. The 5Ni4Ba/YZr catalyst had the highest H 2 formation rate, 1.14 mol g –1 h –1 and lowest apparent activation energy, 20.07 kJ/mol, among all zirconia-supported Ni catalyst systems.

“…In particular, compared to the standard Ni/Al 2 O 3 catalysts, Ni/CeO 2 showed higher activity at low temperature, which allowed for higher selectivity toward methane (this parameter will be discussed in detail in Section 4). Recent trials to improve the performance of nickel catalysts in methanation and methane reforming involved the use of mixed oxide or ternary composites (Al 2 O 3 -ZrO 2 [36], WO 3 -ZrO 2 [37], Ni-Mg-Al [38]) and also doping with transition metals such as Fe, Co, Mn [39].…”

The valorization of carbon dioxide by diverting it into useful chemicals through reduction has recently attracted much interest due to the pertinent need to curb increasing global warming, which is mainly due to the huge increase of CO2 emissions from domestic and industrial activities. This approach would have a double benefit when using the green hydrogen generated from the electrolysis of water with renewable electricity (solar and wind energy). Strategies for the chemical storage of green hydrogen involve the reduction of carbon dioxide to value-added products such as methane, syngas, methanol, and their derivatives. The reduction of CO2 at ambient pressure to methane or carbon monoxide are rather facile processes that can be easily used to store renewable energy or generate an important starting material for chemical industry. While the methanation pathway can benefit from existing infrastructure of natural gas grids, the production of syngas could be also very essential to produce liquid fuels and olefins, which will also be in great demand in the future. In this review, we focus on the recent advances in the thermocatalytic reduction of CO2 at ambient pressure to basically methane and syngas on the surface of supported metal nanoparticles, single-atom catalyst (SACs), and supported bimetallic alloys. Basically, we will concentrate on activity, selectivity, stability during reaction, support effects, metal-support interactions (MSIs), and on some recent approaches to control and switch the CO2 reduction selectivity between methane and syngas. Finally, we will discuss challenges and requirements for the successful introduction of these processes in the cycle of renewable energies. All these aspects are discussed in the frame of sustainable use of renewable energies.
