Аннотация

Nitrogencontaining porous carbon has been produced by acetonitrile vapor deposition at 700 and 800 °C on the products of thermolysis of calcium tartrate doped by iron. The template was removed by dilute HCl acid treatment, and the samples obtained were comparatively studied using transmission electron microscopy, N2 adsorption measurements, thermogravimetric analysis (TGA), Xray photoelectron and nearedge Xray absorption fine structure spectroscopy. It was found that increase in the synthesis temperature results in an extension of the specific surface area from 640 to 670 m2/g, enlargement in the average pore size from 9 to 13 nm, and a decrease in the nitrogen content from 4.4 to 2.7 at%. TGA revealed that the samples differ by 80 °C in the temperature of nitrogen loss, which was desorbed as the NO species mainly. Scheme of nitrogendoped porous carbon synthesis.
