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