Synthesis and Glucose Oxidase Catalytic Properties of Mesoporous Silica/Palladium Nanoparticles

Abstract:

Prepared of Pd/MSN and its catalytic performance on glucose to sodium gluconate were studied in this manuscript. The structure of Pd/MSN was characterized by FI-IR，XRD，SEM and TEM. The catalytic performance of the catalysts used in oxidation of glucose was evaluated. The experimental results showed that Pd/MSN had uniform particle size，higher dispersion and excellent glucose oxidase activity. The optimal condition of the reaction was as follows：4% palladium loading，stirring rate 500 r/min，reaction temperature at 80℃. A catalytic activity of 95.6% was obtained under the optimal preparation condition.
