A Rational Design Strategy for Metal Exchanged Zeolites in the Conversion of Methane to Methanol – A Pathway Towards Commercial Viability

Year: 2024

Type: article

Abstract: Methane is a potent greenhouse gas, and reducing methane released to the atmosphere is crucial in limiting global warming. A promising strategy is to convert methane to higher valuable chemicals right after emission. One class of materials active for this chemistry are metal exchanged zeolites. In this concept paper, we describe how it is possible to rationalize the performance of metal exchanged zeolites for the selective conversion of methane to methanol. We explore how phase diagrams can be used to identify condition dependent active site structures, how synthesis can be used to stir site distribution, and how the performance of single metal sites can be calculated. Combining these three aspects then allows to understand and predict experimentally measured quantities such as methane conversion and spectroscopic signals. In the end, we outline the most promising strategies to bring this technology to industrial feasibility.
