摘要：

Ruthenium catalysts supported on graphite-like carbon material Sibunit modified with rubidium was investigated for the reaction of decomposition of ammonia. Thermal stability of carbon support for synthesized samples of 4% Ru/Sibunit and 8.5% Rb-4% Ru/Sibunit was also studied. It was found that the presence of rubidium reduces the rate of catalyzed particles deposited ruthenium negative reaction of gasification of Sibunit 3 times, in terms of the decomposition reaction of ammonia, and 1.5 times reduced and the activity of the catalyst in the target reaction.
