Abstract

MXenes form an emerging class of two-dimensional (2D) transition metal carbides, carbonitrides, and nitrides with unique electrical, chemical, and structural properties, making them highly attractive for numerous technological applications. Their synthesis relies predominantly on chemical etching processes involving hazardous acids, limiting applications, scalability, safety, and industrial viability. To address this limitation, we explore here Physical Vapor Deposition (PVD) as an innovative, acid-free approach to directly synthesize MXenes without intermediate chemical steps. The research during the period abroad will compare traditionally etched MXenes with materials deposited via PVD, analyzing structural integrity, composition, stability, and functional performance. Hands-on training and collaboration with an internationally recognized research group specializing in MXenes will accelerate critical advancements toward establishing the first effective physical synthesis route. Ultimately, this approach seeks to develop a sustainable, scalable method for synthesizing MXenes and MXene-like (coatings providing intermediate and/or tunable properties, bridging gaps between extreme material characteristics and practical application needs) materials, significantly expanding their potential for future industrial and technological applications.
