“…The phase composition of the nanocarbon was analyzed using a semi-quantitative method using X-ray diffractograms. The morphology and structure of the product were studied under a microscope brand JEM-1400 (JEOL, Japan) using electron illumination microscopy (accelerating voltage-40 to 120 kV, cathode-tungsten), as well as using a scanning electron microscope brand JSM-7001F (JEOL) [28][29].The specific surface area of the samples was determined by the thermal desorption method of nitrogen.…”
