- By means of TG-DTA,XRD,and TEM analysis,the effect of calcinated temperature on their mesoporous structure was investigated and related mechanism was also discussed. 在不引入任何其他辅助离子的前提下,所得样品具有较好的热稳定性。通过TG-DTA,XRD,TEM等表征手段,考察了不同焙烧温度对二氧化锆介孔分子筛结构的影响,并对其机制进行了初探。
- Mesoporous structure Pd catalyst 介孔结构Pd催化剂
- These novel mesoporous materials exhibit large pore size, open mesopore structure, tunable compositions, various morphologies, high mechanical strength and abundant properties. 目前,随着低丰度的后修饰蛋白的深入研究和以小分子为对象的代谢组学的兴起,进一步发展生物质谱技术对于小分子样品的分析、低丰度蛋白的富集和快速酶解新技术显得尤为重要。
- The effect of different content of starch of the samples was studied on the mesopore structure, macropore appearance, hydrothermal stability and enzyme activity to immobilize gluczyme. 因此较大孔径载体材料可能有利于提高酶活性,但这方面的工作很少,值得深入研究。
- By using WTiO with different mesopore structures as matrix, effects of characteristic features of mesoporous matrices on laser desorption/ionization process were investigated in detail. 实验结果发现,不同组分的介孔材料对分析物的电离能力表现出极大差异,材料对样品的电离能力与其紫外吸收趋势相一致,即紫外吸收越强,电离能力越强。
- The two halves of the structure didn't marry up. 该结构的两部分未配合好。
