Experimental studies of the effect of annealing temperature and time of the PECVD process activation stage on the formation of catalytic growth centers of carbon nanostructures were carried out. The dependences of the diameter and height of the catalytic centers on the annealing temperature are obtained. It has been established that exposure in an ammonia atmosphere leads to additional etching of nickel and a decrease in their diameter and height. It has been established that the most optimal temperature for creating with the smallest dispersion of the geometric parameters of the catalytic centers is 750 °C.
