| 中文摘要: |
| 通过4-N,N二甲基胺基吡啶和多金属氧酸负离子形成的复合载体稳定金纳米颗粒,制得金纳米簇-多金属氧酸盐的复合物.复合物的组成以及金纳米颗粒的分布状态由XPS和TEM表征.利用多金属氧酸和金纳米颗粒的相互协助作用,使得这类复合物是一种优异的低温选择性氧化催化剂. |
| 英文摘要: |
| Gold nanoparticles were prepared based on a hybrid compound of 4-dimethylaminopyridine and polyoxometalate as stabilizer,and their composition was characterized by XPS.The dispersion state of gold nanoparticles was observed by TEM.Catalytic cyclohexene oxidation reaction was applied as a model reaction to exam the hybrid's catalytic activity and selectivity.These nanoparticles show high activity and selectivity in catalyzing low-temperature oxidation. |
