In this study, two-dimensional graphene oxide-based novel membranes were fabricated by modifying the surface of oxide nanosheets with six-armed poly(ethylene glycol) (PEG) at room conditions and used for organic solvent nanofiltration applications.
The adsorption behavior of anionic dye congo red (CR) from aqueous solutions using an anion exchange membrane (EBTAC) has been investigated at room temperature. effect several factors including contact time, dosage, ionic strength and temperature were studied. Kinetic models, namely pseudo-first-order pseudo-second-order, liquid film diffusion Elovich models as well Bangham modified freundlich Equations, employed to evaluate the experimental results. Parameters such capacities, rate constant...
Graphene oxide (GO)-based membranes with tunable microstructure and controlled nanochannels have attracted an increasing interest for various applications in wastewater treatment, desalination, gas separation, organic nanofiltration, etc. However, they showed limited use water desalination due to their lower stability separation efficiency. In this work, a class of two-dimensional (2D) GO lamellar been prepared pores efficient fast ions dye molecules. The are fucntionalized star-like 6-armed...
Two-dimensional graphene oxide (GO)-based lamellar membranes have been widely developed for desalination, water purification, gas separation, and pervaporation. However, with a well-organized multilayer structure controlled pore size remain challenge. Herein, an easy efficient method is used to fabricate MoO2@GO WO3@GO nanocomposite interlayer spacing. Such show good separation salt heavy metal ions due the intensive stacking interaction electrostatic attraction. The as-prepared composite...
In this work, we for the first time use a supramolecular compound (p-tetrasulfonato calix[4]arene) as functionalizing agent to modify graphene oxide (GO) nanosheets and prepare unique class of GO/p-TSC4 lamellar membranes, which are then successfully applied removal toxic environmental contaminants from wastewater. The membrane (320 ± 20 nm) exhibits outstanding separation efficiency different organic dyes, e.g., crystal violet, rhodamine B, eosin Y, congo red, methylene blue, with superfast...
Metal–organic frameworks (MOFs), as a new class of porous solid materials, have emerged and their study has established itself very quickly into productive research field. This short review recaps the recent advancement chiral MOFs. Here, we present simple, well-ordered instances to classify mode synthesis MOFs, later demonstrate potential applications MOFs in heterogeneous asymmetric catalysis enantioselective separation.
