Development of Silicalite-1-Encapsulated Ni Catalyst from Ni Phyllosilicate for Dry Reforming of Methane

CO2 (dry) reforming of methane (DRM) is a significant and useful reaction from the standpoint effective utilization conversion two main greenhouse gases to value-added synthesis gas. To achieve highly efficient stable DRM reaction, Silicalite-1-encapsulated ultrafine Ni nanoparticle catalyst (Ni@S-1)by using phyllosilicate (Ni-PS) as precursor was newly developed. This Ni@S-1 exhibited negligible coke deposition (0.5 wt.%) evaluated at 600 °C for 5 h. Additionally, this presented high catalytic performances maintained nanoparticles with size (< 7 nm) 850 24 Therefore, showed good suppression formation resistance nickel sintering thus promising reaction.
