Abstract

Innovating next-generation two-dimensional (2D) membranes necessitates overcoming their selectivity/permeability trade-off limitations. Unlike most 2D multi-stacked membranes, where their water permeability always occurred through the single d-spacing channel, we engineered a novel aquaporin-like multi-functionalized holey graphene (HG) membrane with the potential of tripartite nanochannels. Through this strategy, high selectivity, superior permeability, and chemical stability were achieved. The utilized facile in-situ crosslinking methodology enabled the creation of a unique membrane featuring an aquaporin-like wide/tight interlayer d-spacing decorated with multifunctional SiO₂ nanoparticles, in addition to direct nanochannels of HG. This unique structure boosted the solvent permeability by more than ten times without sacrificing the selectivity. This distinctive membrane category displayed excellent selectivity with a performance higher than 96% for dye rejection. This novel membrane has great potential to be utilized in various organic solvent nanofiltration and wastewater purification applications with extraordinary ability to surpass the permeance/separation trade-off.
