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

摘要:

研究了Pd/MSN纳米粒子的制备及其对葡萄糖的催化性能。利用傅里叶红外光谱（FI-IR）、X射线衍射（XRD）、扫描电镜（SEM）、透射电镜（TEM）等方法对Pd/MSN纳米粒子进行表征，用于葡萄糖氧化制备葡萄糖酸钠的研究，并考察了钯负载量、搅拌速度及反应温度对其催化能力的影响。实验结果表明，Pd/MSN粒径分布均匀，分散性好，且具有较高的催化活性，最佳工艺条件为：钯负载量为4%，搅拌速度为500 r/min，反应温度80 ℃，葡萄糖转化率达95.6%。

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.
