【 摘 要 】

The paper represents the possibility of nitriding of ferroalloy (ferrochromium-aluminum) by the method of self-propagating higherature synthesis. The main ferroalloy nitriding characteristics, such as the nitriding degree and the combustion rate are determined versus the sample diameter, nitrogen pressure and dispersity of the initial powder. Combustion of the alloy is found to take place in a layer-by-layer mode. The photocatalytic activity of the obtained ferrum-containing nitride composites during the degradation of soluble organic matters (dyes, phenol, diclofenac sodium) is evaluated. High efficiency of the obtained materials is observed by combining heterogeneous and homogeneous catalysis.
