Carbide nanoparticles are used in various applications, such as raw material for engineering ceramics and an alternative of noble metal catalysts. Various methods to fabricate carbide nanoparticles are reported, such as CVD and reduction methods. However, these methods tend to need complicated equipment and needs several steps until fabrication, and a more simple way for fabrication is needed. In this work, we report the fabrication of molybdenum carbide nanoparticles by laser ablation of molybdenum in hexane. From various evaluations, we confirmed that the particles have high crystallinity and a core-shell structure.
