Abstract
Effect of a catalyst based on multi-walled carbon nanotubes modified with copper nanoparticles on the kinetics of the catalytic reduction of germanium tetrachloride by hydrogen was studied in the temperature range 423–723 K. Results of experiments were used to determine the reaction order and activation energy. A mechanism of the occurring reaction is suggested on the basis of the data obtained. The introduction of catalysts based on multi-walled carbon nanotubes modified with copper nanoparticles made it possible to lower the reaction temperature and achieve a germanium tetrachloride conversion of about 98%.
