Surface of CuO Nanoparticles Modified by p-Benzoquinone for N₂-Selective Membrane

Membranes, 2022
In this study, CuO nanoparticles and p-benzoquinone (p-BQ) were added to a polyvinylpyrrolidone (PVP) matrix to increase N2/CO2 selectivity. The added p-BQ allowed CuO to be distributed in a uniform size in the PVP/CuO composite membrane and the matrix ...
