Al2o3 Catalyst

Plasma is an efficient method that can activate inert molecules such as methane and carbon dioxide in a mild environment to make them reactive. In this work, we have prepared an AE-NiO/γ-Al2O3 catalyst using an ammonia-evaporation method for plasma promoted dry reforming reaction of CO2 and CH4 at room temperature. According to the characterization data of XRD, H2-TPR, TEM, XPS, etc., the AE-NiO/γ-Al2O3 catalyst has higher dispersion, smaller particle size and stronger metal-support interaction than the catalyst prepared by the traditional impregnation method. In addition, the AE-NiO/γ-Al2O3 catalyst also exhibits higher activity in dry reforming reaction. This work provides a feasible reference experience for the research of plasma promoted dry reforming reaction catalysts at room temperature.
