Synthesis of nitrogen-containing porous carbon using calcium oxide nanoparticles

Nitrogen-containing porous carbon has been produced by acetonitrile vapor deposition at 700 and 800 degrees 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, N-2 adsorption measurements, thermogravimetric analysis (TGA), X-ray photoelectron and near-edge X-ray absorption fine structure spectroscopy. It was found that increase in the synthesis temperature results in an extension of the specific surface area from similar to 640 to similar to 670m(2)/g, enlargement in the average pore size from similar to 9 to similar to 13 nm, and a decrease in the nitrogen content from similar to 4.4 to 2.7 at%. TGA revealed that the samples differ by similar to 80 degrees C in the temperature of nitrogen loss, which was desorbed as the NO species mainly.
