Mesoporous silica supported Ni-based catalysts for methane dry reforming: A review of recent studies

Dry reforming of methane (DRM) emerged as a green alternative to utilize major greenhouse gases (GHG's) and produce syngas. However, the main limitations of DRM are sintering and coking of catalyst. In recent decade the Ni-based catalysts has been meticulously studied for DRM reaction since noble metal-based catalysts can't be commercialized due to economic constraints. The catalyst support, synthesis techniques, effect of promoters can significantly affect the catalyst performance. Mesoporous silica (MS) supported catalysts emerged as a promising material due to their enhanced applications in catalysts with significantly high surface areas, thermal stability, and easy availability. Till date no separate study has been carried out focusing the MS as catalyst support for DRM. This comprehensive review high-lights the recent advances in MS supported catalysts for DRM. Further, it focuses on reaction mechanism, reaction kinetics, thermodynamics, effect of catalyst support, synthesis route and effect of promoters on DRM performance.(c) 2022 Hydrogen Energy Publications LLC.

Automated summary

Dry reforming of methane (DRM) is a green alternative for utilizing greenhouse gases and producing syngas. The main limitations of DRM are catalyst sintering and coking. Recent studies have focused on Ni-based catalysts for DRM due to economic constraints on noble metal-based catalysts. Mesoporous silica (MS) supported catalysts show promise due to their high surface areas, thermal stability, and easy availability. However, research on MS as a catalyst support for DRM is still limited.
