Using anthropogenic carbon dioxide (CO2) as a feedstock for the production of synthetic fuel has gained significant attention in recent years. Among various CO2 conversion pathways, natural gas via methanation holds promise because its potential both recycling and renewable energy storage. Nickel (Ni) ruthenium (Ru) are dominant metals employed catalysts reaction. This review summarizes research landscape Ni- Ru-based over last ten Bibliometric analysis revealed that China highest number publications, Chinese Academy Sciences is foremost academic institution, International Journal Hydrogen Energy leading journal this area research.

The conversion of carbon dioxide (CO2), a major greenhouse gas, into light olefins is crucial for mitigating environmental impacts and utilizing non-petroleum-based feedstocks. Thermo-catalytic CO2 transformation valuable chemicals offers promising solution to this challenge. This study investigates the effect potassium (K) manganese (Mn) promoters on C2H4 selectivity over CoFe-ZSM-5 zeolites. Structural characterization via FTIR, pyridine-FTIR, PXRD confirmed successful incorporation K Mn at 80°C without significant structural changes zeolite framework. BET analysis revealed that metal did not substantially alter surface area, while SEM TEM analyses preservation ZSM-5 spherical morphology. Fixed-bed reactor experiments conducted 350°C 20 bar demonstrated synergistically enhanced efficiency toward C2H4. K-Mn/4Fe4Co-ZSM-5 catalyst (modified with 4% Co Fe) exhibited highest performance, achieving 97% olefin selectivity. Furthermore, reduce CO Co-Fe-ZSM-5 catalyst. These findings underscore critical role in facilitating efficient activation directing reaction pathway products.

CO2 hydrogenation is one of the most effective solutions for mitigating excessive emissions. In this work, CuPdx/γ-Al2O3 (x = 0.05–5.7 wt %) catalysts were prepared and applied in to methanol. The results showed CuPd0.1/γ-Al2O3 achieved excellent activity. It demonstrated that Pd species highly dispersed on γ-Al2O3 support at atomic level separated from Cu nanoparticles by AC-HAADF-STEM, rather than forming CuPd alloy. Part hydrogen activated isolated atoms overflows onto influences reduction CuO, thus effectively increasing Cu+/(Cu++Cu0) ratio which correlated with prominent performance. On other hand, we found CH3OH retained catalyst surface can be further reformed into CO, significantly reduces selectivity CH3OH. To limit reforming, activity test a fixed bed different weight hourly space velocity was performed, where remarkable methanol yields 5.9 mmol/gcat./h obtained.
