METHOD OF SYNTHESISING AND GROWING NANORODS FROM A METAL CARBIDE ON A SUBSTRATE, SUBSTRATES THUS OBTAINED AND APPLICATIONS THEREOF

摘要

The synthesis of metal carbide (M1) nano-rods on a substrate comprises: (a) the deposition, on the substrate, of a layer containing some oxide nano-crystals of metal (M1) and some oxide nano-crystals of at least one metal (M2) different to metal M1, the oxide nano-crystals of metal M1 being dispersed in this layer; (b) the reduction of the oxide nano-crystals of these two metals; (c) the selective growth of the nano-crystals of metal M1. An Independent claim is also included for a substrate incorporating metallic carbide nano-rods fixed on its surface perpendicular to a principal plane of the substrate and physically separated from each other.
