Popis: Carbon nanostructures were synthesized by the pyrolysis of an CH4-H2 mixture. The synthesis was carried out on the Fe-Mo catalysts supported on the SiO2 surface by high-frequency diode sputtering or chemical deposition from a solution of a heterometallic carbonylchalcogenide complex. Structure features of the formed carbon nanostructures affected by the size of catalytic particles, temperature of the process, and composition of the gas mixture were revealed. The presence of sulfur in the catalyst composition results in the formation of nanofibers with the bamboo-like structure.
