3D Assembly of 2D Molybdenum Carbide(Mo2C) Using Chemical Vapor Deposition

Among the burgeoning of novel MXene materials, Molybdenum carbide stands out as they are successfully synthesized by conventional selective chemical etching and chemical vapour deposition growth methods. Molybdenum carbide (Mo2C) is garnering growing research attention due to their interesting chemical and electronic properties. Their properties make them a promising material for future electrochemical energy storage applications. In this work, we show the 3D self-assembly architectures of 2D Molybdenum carbide grown successfully using a chemical Vapor deposition for the first time, to the best of our knowledge. Our controllable CVD approach allows to engineer several aspects of the as grown Mo2C flakes, in particular their orientation of growth with respect to the surface of growth substrate. The as synthesized Mo2C was further investigated by X-ray diffractometry, Raman spectroscopy, scanning electron microscopy and aberration-corrected scanning transmission electron microscopy to gain understanding of the influence of growth conditions on their chemical and structural characteristics.
