Реферат: Carbon xerogels containing various metals are in demand for multiple applications, including electrocatalysis and energy storage systems. Nickel-containing organic xerogels were prepared via a one-pot approach based on sol-gel technology with the addition of citric acid and ethylene glycol during the polycondensation stage. The samples were characterized by several methods, including low-temperature nitrogen adsorption, X-ray diffraction analysis, Raman spectroscopy, and transmission electron microscopy. The pyrolysis of organic xerogels was studied by temperature-programmed carbonization. As found, the pyrolysis procedure performed at temperatures of 800 °C and above resulted in the appearance of partially graphitized carbon xerogels. Partial graphitization of nickel-doped carbon xerogels at Ni content of 2.5 % and such a low temperature as 800 °C is reported for the first time. The specific surface area of the prepared materials exceeded 560 m2/g. Nickel species of 10–100 nm in size were found to be evenly distributed within the carbon matrix.
