Dehydriding reaction kinetic mechanism of MgH2-Nb2O5 by Chou model LIU Yang(刘 杨)1, LI Qian(李 谦)1, CHOU Kuo-chih(周国治)1, 2 1. Shanghai Key Laboratory of Modern Metallurgy and Materials Processing...; Abstract: Chou model was used to investigate the dehydriding reaction kinetic mechanism of MgH2-Nb2O5 hydrogen storage materials at 573 K. A new conception, "characteristic absorption/desorption......
with different kinetic models, including chemical, diffusion (Janders) and mixed mechanism at different heating rates. The results show that, for reactions controlled kinetically by one mechanism, all solid..., kinetics is intrinsically related with the decomposition mechanisms. The knowledge of the mechanism allows the postulation of kinetic equations or vice versa, and kinetics is the starting point......
. Additionally, the kinetic mechanism of thermal decomposition of complex 3 was determined with a TG-DTG curves by both integral and differential methods. The functions of thermal decomposition reaction mechanism and the equation of kinetic compensation effect were obtained. Key words:o-vanillin; p-toluidine; Schiff base; crystal structure; kinetic mechanism of thermal decomposition; rare earths; [全文内......
