MXene Powders

What are MXene Powders?

MXenes are a novel family of two‑dimensional transition metal carbides and nitrides, derived from layered MAX phases through selective etching of the “A” element. In powder form, MXenes exhibit exceptionally high electrical conductivity, tunable surface chemistry, and large specific surface area, making them one of the most promising advanced materials in nanotechnology and energy research.

Key Features

MXene powders are distinguished by their exceptional electrical conductivity, which often rivals that of metals, making them highly effective in advanced electronic applications. Their large specific surface area and layered two‑dimensional structure enable efficient ion transport and adsorption, while the presence of surface functional groups (–OH, –O, –F) allows for versatile chemical tailoring. In addition, MXenes exhibit strong thermal and mechanical stability, ensuring reliable performance under demanding operating conditions. These combined properties make MXene powders a unique class of materials that bridge the gap between traditional conductive additives and next‑generation nanomaterials.

Applications

MXene powders are being actively explored across a wide range of industries. In energy storage, they are incorporated into lithium‑ion batteries, sodium‑ion batteries, and supercapacitors to enhance capacity, rate performance, and cycle life. Their tunable surface chemistry also makes them highly effective in electrocatalysis and sensing, where they improve sensitivity in chemical and biosensors and act as catalysts in hydrogen evolution and CO₂ reduction reactions. Beyond energy and sensing, MXenes are used in nanofluidics and membranes, supporting water purification and ion sieving, and in EMI shielding and protective coatings, where their conductivity and morphology provide robust electromagnetic interference protection. Emerging research further highlights their potential in biomedical applications, including drug delivery and bioimaging, thanks to their biocompatibility and functional surfaces.
