Graphene CVD sheets - updates and market status
There are various methods to produce graphene materials, such as mechanical exfoliation of graphite, liquid-phase exfoliation and reduction of graphene oxide (GO), each with its own set of advantages and disadvantages. Chemical vapor deposition (CVD) is a method of producing graphene that has attracted much attention in the last decade and despite several shortcomings, is considered a leading approach to manufacture graphene, especially for applications like high-performance electronics and sensors, as it can yield high quality graphene sheets with a low defect count and good uniformity.
The CVD process
Generally speaking, the CVD method is based on gaseous reactants that are deposited on a substrate. The graphene is grown on a metallic surface like Cu, Pt or Ir, after which it can be separated from the metal and transferred to specifically-required substrates. When the gases contact the substrate inside the heated reaction chamber, a reaction occurs that creates a film of material on the substrate. The process can be simply explained as carbon-bearing gases that react at high temperatures (900-1100 °C) in the presence of a metal catalyst, which serves both as a catalyst for the decomposition of the carbon species and as a surface for the nucleation of the graphene lattice.
As was mentioned before, conditions like temperature, pressure, duration of time and many more can have a significant influence on the process and so must be carefully monitored.
Advantages and disadvantages
CVD can yield high quality graphene, with common characteristics that may include high homogeneity, imperviousness, high purity, fine grains, good control over layer number and more. However, CVD also comes with several disadvantages - namely a relatively high price of the equipment, toxic gaseous by-products and, as stated before, it is a rather sensitive process that is easily influenced by parameter changes. It is important to note that while CVD is a rather expensive method compared to other methods to produce lower-quality graphene, it is still probably the best way (to date) to acquire high quality graphene, since other ways to do that are even more expensive or complicated.
In addition, the separation (or exfoliation) of graphene from the substrate is known as challenging and it is tricky to accomplish without damaging the structure of the graphene or affecting the properties of the material. Another harrowing task is the creation of a uniform layer of graphene on a substrate, something that is continuously proving to not be easy at all.
Some approaches were and are still being developed to overcome this issue, like modifying the concentration of gases and incorporating spin coating methods, but this remains a challenge. However, despite these challenges, it is important to note that CVD is widely considered as an important and promising method to produce graphene, which is already in use, and will probably be even more so in the future, once further advancements are made. It is noteworthy that CVD is already a dominant manufacturing route for many other nanomaterials, and will assumably be in extremely common use once progress is made to resolve the issues that are currently hindering its acceptance.
Market status
While using the CVD method to produce graphene is definitely one the leading approaches in the world, it is still hindered by the challenges mentioned above. Thus, it is currently mostly limited to relatively small volumes and mainly restricted to R&D and academic uses.
However, graphene sheets produced via CVD methods are used in several applications like sensors, touch screens and heating elements. It is believed that once better answers are found to the questions of price and handling of CVD graphene, many more applications will start to appear.

Graphene Square completes its graphene mass-production plant in Korea
Graphene Square has completed a graphene film mass-production plant at the Blue Valley National Industrial Complex in Pohang, North Gyeongsang Province of Korea. It is regarded as the first attempt in Korea to produce large-area graphene continuously based on factory facilities.
Graphene Square, founded in 2012, signed an investment memorandum of understanding (MOU) with North Gyeongsang Province and the city of Pohang in 2021 and then transferred its headquarters from Suwon to Pohang. A total of 42 billion won was invested in the Pohang plant, which has a total floor area of 6,308㎡. Graphene Square raised a 19 billion won Series B round in 2023 and received a 16 billion won pre-IPO investment in April this year.

Graphene-based molecular sieving separators enhance lithium–sulfur battery stability
Researchers from Purdue University, Vanderbilt University and University of Florida recently reported a graphene-based separator design that addresses critical limitations of lithium–sulfur (Li–S) batteries. While Li–S batteries promise higher energy densities and reduced weight compared to conventional lithium-ion systems, their practical use has long been hindered by the lithium polysulfide (LiPS) shuttling effect, which leads to severe capacity fading and poor cycle life. Traditional approaches, such as slurry-coating LiPS-adsorbing materials onto polypropylene (PP) separators, help mitigate shuttling but increase both mass and volume, thereby reducing the overall energy density of the system.
The research team instead used nanoporous atomically thin membranes (NATMs) composed of graphene, fabricated via chemical vapor deposition, as a lightweight and selective barrier. These graphene layers feature subnanometer pores (~0.7–1.0 nm) that allow the transport of solvated lithium ions (0.54–1.26 nm) while effectively blocking larger LiPS species (0.81–1.69 nm). Owing to their atomic thinness and negligible mass, the membranes function as molecular sieves that suppress polysulfide migration without introducing significant ionic resistance.
New graphene-based approach could take fuel cells to the next level
Researchers from Vanderbilt University, University of Calgary and Western University recently developed a way graphene-based way to improve fuel cell efficiency without sacrificing performance—solving a long-standing challenge in the field.
Fuel cells rely on proton exchange membranes (PEMs) to conduct protons while preventing the unwanted crossover of fuel molecules like hydrogen. Thinner membranes can improve performance by reducing resistance and enabling higher power density. However, this typically comes at a cost: thinner PEMs allow more hydrogen fuel to leak through, reducing overall efficiency. By incorporating a monolayer of chemical vapor deposition (CVD) graphene into PEMs, the team significantly reduced hydrogen crossover by more than 50% while maintaining excellent proton conductivity. The graphene layer with pores at the atomic and nanoscale acts like a selective barrier, allowing protons to pass while blocking larger molecules such as hydrogen gas.

Researchers develop graphene membranes with pyridinic-nitrogen at pore edges for high-performance CO2 capture
Researchers at École Polytechnique Fédérale de Lausanne (EPFL) have developed advanced graphene membranes with pyridinic-nitrogen at pore edges, reportedly showing unprecedented performance in CO2 capture. This could mark a step towards more efficient carbon capture technologies.
Carbon capture, utilization, and storage (CCUS) is a technology that reduces carbon dioxide (CO2) emissions from hard-to-abate industrial sources such as power plants, cement factories, steel mills, and waste incinerators. But current capture methods rely on energy-intensive processes, which makes them costly and unsustainable. Researchers are working to develop membranes that can selectively capture CO2 with high efficiency, thereby reducing the energy and financial costs associated with CCUS. But even state-of-the-art membranes, such as polymer thin films, are limited in terms of CO2 permeance and selectivity, which limits their scalability. So, the challenge is to create membranes that can simultaneously offer high CO2 permeance and selectivity, crucial for effective carbon capture.
