Heterogeneous catalysts for hydrogen production from methane and carbon dioxide

Abstract

Several heterogeneous catalysts were studied for synthesis gas production through dry reforming of methane (DRM). This process uses carbon dioxide in lieu of the steam that is traditionally used in conventional methane reforming to produce hydrogen that can then be repurposed in more chemical processes [2]. The monometallic catalysts explored were Ni/Al2O3 and Ni/CeZrO2 followed by their bimetallic versions PtNi/Al 2O3 and PtNi/CeZrO2 at 800°C. In addition to these catalysts, platinum supported Zeolitic Imidazolate Framework (ZIF)-8 was also investigated in comparison with PtNi/CeZrO2 at 490°C. The studies suggest that these catalysts are suitable for promoting the dry reforming of methane for hydrogen production
