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 negligib...
