Abstract The development of high-performance carbonaceous microwave absorbers to achieve full X band (8.2–12.4 GHz) efficient microwave absorption with lower filler loading ratio is highly desirable but remains challenging. Here, a kind of hollow graphene nano-spheres uniformly confined in porous amorphous carbon particles (HGS@PAC) are fabricated ...

Nano-Porous Graphene as Free-Standing Membranes
2021Membrane-based treatments are superior to conventional processes in water purification and desalination in terms of final water quality and smaller footprint. In addition, there are inherent weaknesses of state-of-the-art membranes in reverse osmosis (RO) technology, thus there is pressing constraints for next-generation membranes. Nano-porous graphene

Alkali activated porous material with nano graphene oxide as adsorbent in wastewater treatment
Materials Today: Proceedings, 2021Abstract Removal of contaminants, impurities and suspended solid matter are termed as water treatment. The possible water treatment methods are coagulation, filtration, ion exchange, aerobic and non aerobic methods. But all this involves high cost. Earlier filtration using granular sand was termed as the efficient way of water treatment.

Engineering nano-porous graphene oxide by hydroxyl radicals
Carbon, 2016Abstract Graphene oxide (GO) has recently been identified as an excellent candidate for membrane science, but the relatively small number of channels for species to transport across the laminated GO membranes is one of the major limitations for the membrane permeability.

Permeability Analysis of Pure Water across Nano Porous Graphene
2019 International Conference on Electrical, Computer and Communication Engineering (ECCE), 2019Being the thinnest and strongest material, graphene has tremendous potential for water desalination. This paper reports the analysis of water permeability across single layer free standing nano porous graphene. Using classical molecular dynamics simulation, it has been found that the permeability of water through graphene is depended on its pore ...

Journal of Applied Polymer Science, 2023
AbstractThis research studies the improving effects of graphene porous (GP) on the supercapacitive performance of a polyaniline/graphene porous (PANI/GP) nanocomposite. GP nanosheets were synthesized via chemical vapor deposition, and PANI/GP was electrochemically composited through successive cyclic voltammetry.

Two-Dimensional Porous Micro/Nano Metal Oxides Templated by Graphene Oxide
ACS Applied Materials & Interfaces, 2015Novel two-dimensional (2D) porous metal oxides with micro-/nanoarchitecture have been successfully fabricated using graphene oxide (GO) as a typical sacrificial template. GO as a 2D template ensures that the growth and fusion of metal oxides nanoparticles is restricted in the 2D plane.

First-principles design of nano-porous graphene membranes for efficient separation of halogen gases
Diamond and Related Materials, 2020Abstract The development of efficient membranes for separating the mixture of gases is an active area for research. Atomically thick layers of 2-D materials can serve as a potential candidate for ultra-thin membranes. Here, we investigated the capability of nano porous graphene (NPG) membranes towards efficient halogen separation.
