A process for the synthesis of 4d and 5d (Nb, Mo, Ta, W) nitrides of transition metals in form of quasi-one-dimensional structures

摘要

the object of the invention is a process for the synthesis nitridov 4d and 5d transition metal (nb, mo, w) in the form of quasi enodimenzionalnih structures, it is nanou017eic, mikrou017eic, nanotrakov and mikrotrakov.the invention includes the synthesis nitridov transition metals in the form of quasi enodimenzionalnih structures with the method of conversion of quasi enodimenzionalnih compounds with podmikronskim cross-section nanou017eic described with the formula m6cyhz, 8.2 smaller than y + z is less than 10, where m is the transition metal (nb, mp, w) c is halkogen (sulfur (a), selenium (se), tellurium (te); (h) the halogens iodine (i)) by heating in the presence of ammonia.this procedure allows for the synthesis of large quantities of nitridov 4d and 5d (nb, mo, w) of transition metals in the form of quasi enodimenzionalnih structures (nanou017eic, mikrou017eic, nanotrakov and mikrotrakov).
