Are carbon nanotubes graphene?
Both graphene, and carbon nanotubes, are made from carbon atoms. Carbon nanotubes, on the other hand, are made by curling graphene. Carbon nanotubes, which are made up of hexagonal tubes of several tens or hundreds of layers of carbon atoms, are formed by arranging the atoms in hexagons. Carbon nanotubes look like graphene (a hexagonal carbon grid) that has been rolled up. Both graphene (a hexagonal lattice of carbon) and carbon nanotubes are characterized by extraordinary mechanical and electrical properties.

Research on carbon nanotubes, as it stands, has reached an advanced level in terms of preparation, performance characterization, and application exploration. Due to their close connection, both research methods have many similarities. Carbon nanotubes were the original inspiration for many graphene-related research methods.

What is different between carbon nanotubes (CNT) and graphene (Graphene)?

Graphene, a two-dimensional substance, is a layer graphite with carbon atoms arranged hexagonally in a honeycomb lattice. Carbon nanotubes consist of hollow cylindrical structures. They are basically a graphene layer rolled into an cylinder. Both are representative of two-dimensional nanomaterials (2D) as well as one-dimensional (1D).

From a structural perspective, carbon nanotubes represent a carbon crystal with a one dimensional structure. Graphene, on the other hand, is composed of just a single carbon layer and is therefore a true, two-dimensional, crystal structure.

Graphene, from a performance perspective, has properties that are comparable or superior to those of carbon nanotubes. These include high electrical conductivity and thermal conductivity; high carrier mobility; free-electron space and high strength and rigidity.

According to the number layers, they are divided into single walled carbon nanotubes and multiple-walled graphite nanotubes. The single-walled carbon Nanotubes are also a division. Layer graphene or graphene microplatelets.

Is graphene as strong as carbon nanotubes

Both graphite and carbon nanotubes are graphite in essence. But the arrangement and combinations of carbon atoms differ, creating spiral carbon nanotubes or sheet-shaped graphene. They both share some graphite characteristics.
In the long term, graphene has a superior ability to transfer its mechanical and strength properties to a host material than carbon nanotubes. In the present research, carbon nanotubes achieved similar results. However, graphene has more advantages over the long term due to its unique two-dimensional design and application.

Although graphene, and carbon nanotubes share a common pre-existence they will likely have a very different future. The dispute between two-dimensional and three-dimensional material is the primary cause. Nanowires and microtubes often have a disadvantage when competing against thin-film material. As an example, carbon nanotubes. Carbon nanotubes can be considered as single crystals with high aspect ratios. However, current synthesis technology and assembly techniques cannot create carbon nanotubes of macroscopic size, thus limiting their use in carbon applications. The two-dimensional graphene crystal structure has several properties that are unmatched (strength and electrical conductivity as well heat conduction) and it can grow in an area of a very large size. Combining bottom-up with top-down can lead to exciting future application possibilities.

How does graphene convert into carbon nanotubes

For carbon nanotubes to be formed, graphene and the carbon atoms are manipulated into a thin plate that is then rolled up into a tube. The graphene sheets that are used to produce nanotubes have a two-dimensional structure because graphene has only one atom thickness.
New graphene and carbon nanotube catalyst can ignite a clean-energy revolution

Researchers have developed promising graphene/carbon nanotube catalysers to better control chemical reactions important for the production of hydrogen fuel.

Hydrogen fuel economy will be based on cheap, efficient fuel cells and electrolyzers. This is one the most promising and clean alternatives to fossil fuels. The electrocatalysts that are used in these devices make them work. Developing low-cost, efficient electrocatalysts will be crucial for making hydrogen fuel viable. Researchers from Aalto University created a new kind of catalyst material for these technologies.

The team, in collaboration with CNRS, created a graphene-carbon-nanotube hybrid that is highly porous and contains single atoms known to act as good catalysts. Carbon nanotubes are allotropes, or two-dimensional or one-dimensional carbon sheets that are just one atom thick. Carbon nanotubes and graphene are more popular than traditional materials in the industry and academia due to their exceptional performance. The world has shown great interest. They developed an easy and scalable way to grow all these nanomaterials together and combine their properties into a single product.

The catalyst is typically deposited onto the substrate. Researchers ignore the substrate’s role in the final reaction of the catalyst. But for this type of catalyst, they found that it plays a significant role in its efficiency. The researchers discovered that the porous nature of the material allowed it to access more catalyst sites located at the interface between the substrate and the material. The researchers developed a new electrochemical microscopy analysis method to determine how the interface contributed to the catalytic process and to produce the most potent catalyst. The researchers believe that their research into the influence of the porous material matrix on the catalytic reaction will provide the basis for rational design and development of high-performance electrochemical energy devices.
