Metallocene catalysts on carbon-based nano-materials |
| 초록 |
Metallocene, which has transition metal atoms sandwiched by aromatic rings, is one of the representative systems for organometallic catalysts. Group 4-based metallocene catalysts have been most commonly used for the production of polyolefins, which have great world-wide markets in the real life. Graphenes and carbon nanotubes (CNTs) were composed of extended sp2 carbon networks, showing high electron mobility as well as have extremely large steric bulkiness relative to metal centers. A few example of chemically modified graphenes (CMGs) showed interesting performances as a catalysts or as a supporter in catalytic reactions. In this work, a reduced graphene oxide (RGO) was attached on a zirconocene and separately, on a titanocene. Resulting hybrid systems showed excellent catalytic performances for ethylene polymerizations and produced polyethylenes (PEs) with extremely increased molecular weights relative to free catalytic systems without graphene materials. |
