Tuning Zeolite Properties towards CO ₂ Methanation: An Overview

This work provides a short review of the literature concerning the utilization of zeolites as supports for CO ₂ methanation catalysts. Indeed, the application of these materials in carbon dioxide hydrogenation into methane has led to considerably relevant performances according to the literature, being zeolite-based catalysts more active and selective than commercial materials reported. Considering the well-known zeolite features and the possibility to finely modulate its properties, inducing relevant changes on the adsorbed metal species and in the CO ₂ activation ability of the catalyst, potentially interesting catalytic properties can be generated also towards this transformation. Possible correlations between the characteristics of these materials, found as relevant for CO ₂ methanation, and the catalytic properties will be then presented and discussed.
