Lanzhou Institute of Chemical Technology has developed a new method for one-step synthesis of nanoporous graphene

Chiral separation is a challenge faced by separation science.

The Chiral Separation and Micro-Nano Analysis Group of Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences focuses on the synthesis of nanoporous graphene and its application in separation analysis

Generally, the synthesis of graphene oxide by Hummers method is divided into three reaction stages: low temperature, medium temperature and high temperature.

The researchers combined mechanical stirring and rapid suction filtration to prepare nanoporous graphene with different pore diameters into nanoporous graphene separation membranes

Previously, researchers used heavy ion accelerators to prepare single-layer nanoporous graphene ion separation membranes (Analytical Chemistry); later, they developed a simple and fast new method for combustion synthesis of nanoporous graphene (Advanced Functional Materials, Chinese Chemical Letters) And metal oxide nano two-dimensional material interlayer confinement synthesis technology (ChemNanoMat), the nanoporous graphene is applied to the highly selective membrane separation of ions

Related research results were published in Analytical Chemistry.
