Highly Efficient and Stable Blue Light-Emitting Poly(fluorene-co-2,7-carbazole-co-3,7-dibenzothiophene-S,S-dioxide)s
关键字：Poly(fluorene-co-2,7-carbazole-co-3,7-dibenzothiophene-S,S-dioxide)s
Recently, dibenzothiophene-S,S-dioxide as a new electron-deficient moiety was incorporated into oligomers or polymers owing to its high electron affinity energy and fluorescence efficiency.1,2 We incorporated 3,7-dibenzothiophene-S,S-dioxide into polyfluorene ...

Supercritical Carbon-Dioxide-Assisted Deposition of Pt Nanoparticles on Graphene Sheets and Their Application as an Electrocatalyst for Direct Methanol Fuel Cells
关键字：graphene ， supercritical carbon dioxide ，Electrocatalyst
A combination of graphene with metal particles is particularly attractive due to the enhanced performance of the hybrid materials. However, direct loading of uniform metal
nanoparticles such as Pt on graphene remains a challenge due to the hydrophobic nature of graphene. We herein demonstrate that Pt nanoparticles with uniform size and high dispersion were deposited on graphene surfaces via a faci...

Methanol electrocatalytic oxidation on highly dispersed platinum–ruthenium/graphene catalysts prepared in supercritical carbon dioxide–methanol solution
关键字：graphene， supercritical carbon dioxide，PtRu
An effective, simple, low temperature and environmentally benign supercritical fluid (SCF) route is presented for preparing graphene-supported metal nanoparticles. With the assistance of supercritical carbon dioxide (SC CO2), ultrafine PtRu nanoparticles with an average size of 2.87 nm were very uniformly distributed on the surfaces of functionalized graphene sheets (FGSs) by the reduction of a mi...

Alternating Copolymerization of Carbon Dioxide and Cyclohexene Oxide Catalyzed by Silicon Dioxide/Zn-CoIII Double Metal Cyanide Complex Hybrid Catalysts with a Nanolamellar Structure
Air-stable hybrid catalysts of silicon dioxide/double metal cyanide complexes(Si-DMCCs) based on Zn3[Co(CN)6]2 (ZHCC) were prepared by an in situ sol–gel method. The Si-DMCCs showed low crystallinity and a nanolamellar structure with a thickness of 40–60 nm. In particular, a lamellar structure of regular hexagonal shape was observed for Si-DMCCs with low SiO2 content. These catalysts had very h...
