To investigate the influence of Ag and loading Ni species, Ni-Ag type catalysts were synthesized with varying Ni/Ag ratios (1, 1.5 2) using coprecipitation method. The extensively characterized various techniques such as TG-DSC-SM, XRD, ICP, BET, SEM-EDX TPR subsequently tested in CH4/CO2 reaction without any pretreatment. Regardless ratio employed, a phase mixture containing NiO was observed after calcination under air between 600 °C 1200 °C. SEM analysis confirmed presence close interface NiO. specific surface area found to be significantly higher for catalyst lower content (R = 1). demonstrated that inclusion facilitated reduction at temperatures. XRD analyses spent during reaction. Among samples, 1 exhibited superior catalytic activity pretreatment atmosphere, which case conversions methane CO2 650 amounted 38 45 mol%, respectively, H2/CO 0.7 71 mol% H2. species enhances stability improves performance dry reforming methane.
