Catalytic Decomposition of Ammonia on Coatings Consisting of Organoboron and Platinum Nanoparticles

Аннотация

Comparative characteristics of catalytic activity of electroneutral and positively charged coatings consisting of organoboron nanoparticles with a composition (C₂B₁₀H₄)_n or platinum in ammonia decomposition have been obtained for the first time. The charge on the coatings was created by the supply of a positive voltage of +6 or +10 V. It has been found that, for the same mass of the coatings at 700 K and a pressure of 5 × 10^–7 Torr, the rate of ammonia decomposition on a coating consisting of organoboron nanoparticles is 28–43% of the rate of NH₃ decomposition on the coating consisting of platinum nanoparticles depending on the voltage supplied to the coatings.
