Single Layer Graphene Oxide Nanopowder with High Purity 99.8%

Single Layer Graphene Oxide Nanopowder 

Introduction

Single layer Graphene Oxide nanopowder is a single-atom-thick sheet of carbon atoms arranged in a hexagonal lattice with various oxygen-containing functional groups, such as hydroxyl, epoxy, and carboxyl groups, attached to its surface. Graphene oxide nanopowder refers to a fine powder form of graphene oxide that is composed of nanoscale sheets, typically ranging from a few nanometers to micrometers in size.

Applications

Energy Storage:

Supercapacitors: The high surface area and tunable properties of single-layer graphene oxide make it an excellent candidate for use in supercapacitors, where it can act as a conductive material or be used in composite electrodes for higher energy and power densities.

Lithium-ion Batteries: Single-layer GO nanopowder can be incorporated into electrode materials to enhance the conductivity and cycling stability of lithium-ion batteries.

Composite Materials:

Polymer Composites: Due to its high surface area and ability to be uniformly dispersed in polymer matrices, single-layer GO is often used to reinforce polymers, improving their mechanical properties, conductivity, and thermal stability.

Nanocomposites: GO nanopowder can be combined with metals, ceramics, and other nanomaterials to create composite materials with unique properties for a wide range of structural and functional applications.

Water Purification:

Adsorption of Contaminants: Graphene oxide’s large surface area and ability to functionalize its surface make it highly effective for adsorbing heavy metals, organic contaminants, and dyes from water, making it a potential material for water filtration.

Desalination: Recent studies have demonstrated that GO can be used in advanced membrane technologies for desalination and separation processes, leveraging its nanostructured form to filter out salt and other contaminants.

Sensing and Biosensors:

Chemical Sensors: Single-layer graphene oxide nanopowder can be functionalized with various chemical groups to selectively detect gases or organic molecules, making it an excellent candidate for chemical sensors.

Biosensors: GO-based biosensors are used for the detection of biomolecules, such as DNA, proteins, and viruses, because GO’s surface can be modified to interact specifically with biological targets.

Biomedical Applications:

Drug Delivery: Single-layer graphene oxide can be used as a drug delivery vehicle due to its ability to carry large amounts of functionalized molecules on its surface. It can be engineered to target specific tissues, improving the delivery and release of therapeutic agents.

Imaging and Diagnostics: GO can also be used as a contrast agent in imaging techniques like fluorescence and MRI, enhancing the visibility of tissues or biomolecules in medical imaging.

Tissue Engineering: In combination with biomaterials, GO can support cell growth and differentiation, making it useful in tissue engineering for applications such as wound healing and bone regeneration.

Catalysis:

Catalyst Support: The oxygenated groups on graphene oxide provide active sites that can be utilized to support catalytic reactions, particularly in the context of metal nanoparticles. GO-based catalysts are being studied for their potential in environmental cleanup and chemical manufacturing.

Electrocatalysis: Single-layer GO nanopowder is also explored for electrocatalytic applications, including fuel cells and batteries, where it can play a role in reactions like oxygen reduction and hydrogen evolution.
