High-performance asparagine-modified graphene oxide membranes for organic dyes and heavy metal ion separation

Abstract

Graphene oxide (GO) lamellar membranes have attracted a lot of attention as a possible solution for water purification applications. In this work, asparagine amino acid-modified GO-based membranes (As@GO) are prepared...

Ultrafast Graphene Oxide-Lignin Biopolymer Nanocomposite Membranes for Separation of Biomolecules, Dyes, and Salts

“…GOLB and GOMs were prepared according to reported method. 31 GOLB membrane was prepared by dispersing a certain amount of GOLB composite (1:1 of GO and lignin) into DI water using tip sonication. Different from the whitish color of lignin (Figure 1a) and brown color of GO dispersion (Figure 1b), the GO and lignin blend shows a dark black color (Figure 1c).…”

Recent progress in 2D and 3D metal–organic framework-based membranes for water sustainability

“…Several crucial parameters and requirements, such as high-water permeability, high salt rejection, and durability, are required for the desalination of MOF-based membranes. 158 Compared to other desalination technologies, 159–162 MOF-based membranes offer several advantages, such as high desalination efficiency. They are also flexible in terms of design, allowing for tailoring of the pore size and surface chemistry to optimize performance.…”

Fabrication of a symbiotic polyvinyl alcohol-functionalized NiO/rGO nanoadsorbent for control of bisphenol-a removal

“…44,46–48 Due to these exceptional properties, GO has been widely employed in separation science, energy storage, sensing devices, catalysis, optoelectronic devices and lithium-ion batteries. 49–52 On the other side, the rGO is a derivative of GO that is formed by the reduction of GO nanosheets using a reducing agent to improve its physical and chemical properties. 53–56 It is an excellent 2D material 57 and can be easily functionalized using polymers, biomolecules, and metal and metal oxide nanoparticles.…”
