Strategies to protect versatile 2D nanomaterials from rapid oxidation
In short: Researchers exploring the potential of MXenes—a class of two-dimensional transition metal carbides and nitrides—have identified significant hurdles in their use. While these materials offer unique physical and chemical properties for various technologies, they are highly susceptible to oxidative degradation when exposed to normal environments.
This review examines how factors like temperature, atmosphere, composition, and microstructure influence the oxidation of MXenes. By understanding these dynamics, scientists can develop methods to delay or prevent degradation in complex settings, particularly at high temperatures.
The study systematically reviews preparation methods and thermal stability across different environments. A limitation of this work is that it serves as a review of existing research rather than presenting new primary experimental data.
Why it matters: Understanding the chemistry of oxidation is key to unlocking 2D materials for high-temperature and complex industrial applications.
