Zeolite-based materials for greenhouse gas capture and conversion

The global warming caused by greenhouse gas emissions, principally carbon dioxide (CO₂) and methane (CH₄), has become a great threat to human survival. The capture and conversion of CO₂ and CH₄ not only provide an effective method to reduce the greenhouse gas emissions towards achieving carbon neutrality but also produce sustainable chemicals and fuels to meet the increasing demand for chemicals and energy. Zeolite-based materials are excellent adsorbents and catalysts for CO₂ and CH₄ capture and conversion. In this mini-review, we present the recent progress in zeolite-based materials for CO₂ and CH₄ capture and conversion. We first discuss the key factors of zeolites on the CO₂ and CH₄ adsorption performance. Then, we demonstrate the catalytic conversion of CO₂ and CH₄ into value-added chemicals, including hydrocarbons, oxygenates, and syngas. Finally, we provide an outlook regarding the opportunities and challenges for the capture and conversion of CO₂ and CH₄ towards achieving carbon neutrality and sustainable development.
