Scientists have revealed safer electrochemical methods to make “miracle material” MXene.
Researchers at TU Wien have developed a safer and more non-toxic electrochemical method to produce MXene, an outstanding two-dimensional material that can be applied to energy storage, sensors, and solid lubrication. This innovative technology is expected to eliminate the need for harmful hydrofluoric acid (HF), thereby enabling production on an industrial scale.
MXene, a nanomaterial used in battery technology and high-performance lubricants, was previously difficult and dangerous to produce. However, the researchers have now developed a new and safe way to produce MXene.

One of the most groundbreaking trends in material science is the study of two-dimensional (2D) materials consisting of single atomic layers. These materials often exhibit completely different properties from bulk materials composed of the same elements. The field of research was further developed with the subsequent discovery of the Nobel Prize-winning graphene.
Today, a new 2D material called MXene (pronounced “Max N”), which is mainly composed of titanium and carbon, is attracting attention.

MXene offers a variety of amazing properties. It shows promising potential in fields such as electromagnetic shielding, energy storage, and advanced sensing technologies.
Surprisingly, the researchers found that [MXene functions very effectively as a solid lubricant even in extreme environments such as space].
However, the main obstacle was that conventional MXene production methods, which rely on strong acid, were dangerous and highly toxic. Now those issues have been resolved. The research team at TU Wien has developed a safer, electric-based synthesis process that does not use toxic chemicals. The breakthrough technology was published in the prestigious journal Small.
2. No more toxic hydrofluoric acid
To produce MXene, you first need the so-called MAX phase. The phase is a material that can consist of layers of aluminum, titanium, and carbon, for example. Hydrofluoric acid has been used to etch aluminum in the MAX so far, resulting in a system in which thin layers slide and move with little resistance to each other at the atomic level. This is why MXene is a great lubricant.

However, dealing with hydrofluoric acid is not an easy task. There are strict regulations on the handling of these chemicals, which are toxic and harmful to the environment. Special and expensive laboratory equipment is required, and waste disposal is also expensive.
This was why MXene has not yet made great progress in the industry. It is natural that many companies are reluctant to take these steps because it is difficult to build such a process on an industrial scale.

So the team started looking for a better way. [It’s electrochemistry]
Electrochemicals provide an alternative way to break the aluminum bond on the MAX. When a voltage is applied, a current flows on the MAX, and this current starts the reaction at the interface. By precisely adjusting the voltage, only aluminum atoms are removed and the reaction may be adjusted so that electrochemical MXene (EC-MXene) is produced.

The research team has found that a very specific electrochemical technique can be used to improve the overall quality of electrochemical etching and EC-MXene. It is an appropriate amount of current pulse. Using other methods, the surface reactivity rapidly decreases, while the short current pulse forms a small hydrogen bubble in the MAX phase material to clean and reactivate the surface. This allows the electrochemical reaction to last longer and produce a large amount of EC-MXene.
The obtained products were analyzed using advanced techniques such as atomic force microscopy, scanning and transmission electron microscopy, Raman and X-ray photoelectron spectroscopy, and low-energy ion scattering. Its properties are as good as those of MXene previously produced using hydrofluoric acid. Pierluigi Bilotto said, “My goal is to make the synthesis of MXene very simple. It would be possible in any kitchen. And we were very close to that goal.
