Abstract Catalytic methane decomposition is a promising technology for reducing the reliance on fossil fuels and mitigating effects of climate change by producing clean hydrogen value‐added carbon without emission greenhouse gases. The aim study was to investigate use Al 2 O 3 ‐modified MgO doped iron‐based catalysts catalytic methane. were synthesized using impregnation method characterized various analysis techniques, including Brunauer, Emmett, Teller, temperature programmed reduction, oxidation, X‐ray diffraction, thermal gravimetric analysis, Raman, scanning electron microscopy, transmission microscopy. activity tested in packed‐bed reactor with gas flow rate 20 mL/min at 800°C. investigation focuses influence incorporating magnesium into alumina concentration ranging from (20%–70%), where higher levels improve creating more active sites, positively impacting decomposition. Enhanced catalyst reducibility increased particle dispersion lead improved properties despite reduced surface area. FA70M FA63M exhibited almost same characteristics highest stability conversion among investigated, reaching 87% 85% 800°C 120 min. Moreover, both showed yields 86% 85%, respectively. introduction further total yield 103% FA 39% FM 114% 120% respective (FA70M FA63M). During reaction, nanotubes varying diameters produced. Higher iron loading resulted positive trend.

Methane decomposition is a promising route to synthesize COx -free hydrogen and carbon nanomaterials (CNMs ). In this work, the impregnation method was employed for preparation of catalysts. Systematic investigations on activity stability Fe-based catalysts were carried out in packed-bed micro-activity reactor at 800 °C with feed gas flow rate 18 mL/min. The effect doping Y2 O3 , MgO, SiO2 TiO2 over ZrO2 catalytic performance also studied. BET revealed that specific surface areas pore volumes are increased after added while MgO had negative impact hence little decrease area observed. results showed catalyst supported -doped is, Fe-TiZr, demonstrated highest stability, maximum methane conversion 81.3 % during 180 min time-on-stream. At °C, initial 73 %, 38 64 69 final yield 121 wt. 55 354 174 achieved using Fe-MgZr, Fe-SiZr, Fe-TiZr Fe-YZr catalysts, respectively. Moreover, bulk deposition uniform nanotubes high degree graphitization different diameters observed

Abstract Dry methane reforming (DRM) presents a viable pathway for converting greenhouse gases into useful syngas. Nevertheless, the procedure requires robust and reasonably priced catalysts. This study explored using cost‐effective cobalt nickel combined single catalyst with different metal ratios. The reaction was conducted in fixed reactor at 700 °C. findings indicate that incorporation of significantly enhances performance by preventing sintering, improving dispersion, promoting beneficial metal‐support interactions. best‐performing (3.75Ni+1.25Co‐ScCeZr) achieved good conversion rate CH 4 CO 2 46.8 %, 60 % respectively after 330 minutes while maintaining stability. TGA ‐TPD analysis results show addition Co to Ni reduces carbon formation, increases amount strong basic sites isolated O − species, total desorbed. These collectively highlight potential cobalt‐nickel catalysts practical DRM applications contribute developing sustainable energy technologies.
