Metal Borides: From Industrial Classics to Versatile Colloidal Nanocrystals for Energy, Catalysis, and Hard Coatings Applications†

Abstract

Metal boride (MxBy) nanocrystals (NCs) represent a cutting-edge and promising materials class that has gained significant attention in nanotechnology and materials science. The distinct combination of metal and boron at the nanoscale imparts exceptional mechanical, electronic, and thermal characteristics to these materials, making them highly desirable for various technological applications. MxBy NCs exhibit remarkable hardness, thermal stability, and resistance to wear, rendering them suitable for applications in high-performance materials, coatings, and cutting-edge electronic devices. The nanoscale size of these crystals further enhances their reactivity, properties, and surface area, opening up new possibilities for catalytic processes and energy-related applications. Researchers are actively exploring various methods of synthesizing these materials, their structural properties, and potential applications, aiming to unlock their full potential for innovations in diverse fields ranging from materials engineering to energy storage. This perspective sets the stage for a deeper exploration into the fascinating world of metal boride NCs and their transformative impact on various technological frontiers.
