Phenolic Resin‐Functionalized NH2‐UiO‐66‐Containing Mixed Matrix Membranes for CO2/CH4 Separation

open access: yesEcoEnergy, EarlyView.
Phenolic resin‐functionalized small‐size RFin@NH2‐UiO‐66 nanofillers were prepared and combined with polyetherimide (PEI) matrix to construct mixed matrix membranes for effective CO2/CH4 separation. ABSTRACT For mixed matrix membranes (MMMs), the inherent structural features and composition of the embedded nanofillers play a pivotal role in governing ...
