Deep eutectic solvent coated cerium oxide nanoparticles based polysulfone membrane to mitigate environmental toxicology
In this study, ceria nanoparticles (NPs) and deep eutectic solvent (DES) were synthesized, and the ceria-NP’s surfaces were modified by DES to form DES-ceria NP filler to develop mixed matrix membranes (MMMs). For the sake of interface engineering, MMMs of 2%, 4%, 6% and 8% filler loadings were f...

Summary: | In this study, ceria nanoparticles (NPs) and deep eutectic solvent (DES) were synthesized,
and the ceria-NP’s surfaces were modified by DES to form DES-ceria NP filler to develop mixed
matrix membranes (MMMs). For the sake of interface engineering, MMMs of 2%, 4%, 6% and 8% filler
loadings were fabricated using solution casting technique. The characterizations of SEM, FTIR and
TGA of synthesized membranes were performed. SEM represented the surface and cross-sectional
morphology of membranes, which indicated that the filler is uniformly dispersed in the polysulfone.
FTIR was used to analyze the interaction between the filler and support, which showed there was no
reaction between the polymer and DES-ceria NPs as all the peaks were consistent, and TGA provided
the variation in the membrane materials with respect to temperature, which categorized all of the
membranes as very stable and showed that the trend of stability increases with respect to DES-ceria
NPs filler loading. For the evaluation of efficiency of the MMMs, the gas permeation was tested. The
permeability of CO2 was improved in comparison with the pristine Polysulfone (PSF) membrane
and enhanced selectivities of 35.43 (αCO2/CH4) and 39.3 (αCO2/N2) were found. Hence, the DES-ceria
NP-based MMMs proved useful in mitigating CO2
from a gaseous mixture. |
