| Abstract: | Kinetics of oxidation of benzyl alcohol catalyzed by nanoporous metal-organic frameworks Cu3(BTC)2(H2O)3was studied using UV-Vis spectral method.It was found that the apparent first-order rate constant increased remarkably with the increasing of pH,molar ratio of the catalyst to the substrate and reaction temperature.Based on the experimental results,catalysis mechanism for the catalytic oxidation was discussed,and a kinetic model was proposed.The apparent activation energy(Ea),association equilibrium const... |
