Dendrimer-coated metallic catalyst performance improves significantly.

Dendrimer-coated metallic catalyst performance improves significantly.
Dendrimer-coated metallic catalyst has the following advantages: ① using pure metal particles as catalyst, the mutual attraction between the particles make catalyst agglomeration and the catalyst activity decreased, while after coated by dendrimer, it can prevent agglomeration, improve the catalytic ability; ②interior nano cavity environment of dendrimer has a strong selective catalytic function ; ③dissolve in environment-friendly water, supercritical CO2 , organic solvents and volatile Freon etc. when in the reaction with the characteristics of homogeneous catalysis; ④ as it is such a nano-size molecules, can be separated by a simple separation techniques (such as nanofiltration or dialysis) from the homogeneous reaction mixture.
