Observation of Early to Full Covering Stages of Ethylene-based CVD of Graphene

Celebi K., Choi J.W., Cole M.T., Altun A.O., Teo K.B.K., Park H.G., ETH Zürich, CH

Scalable growth of graphene has been demonstrated by chemical vapour deposition (CVD) using copper-based catalyst and ethylene precursor. Here, we present our ethylene-based CVD synthesis method of graphene along with our observation of early and [...]

The Characteristics and Photocatalytic Activity of Visible Light Driven N-doped TiO2

Hsu H-J, Lin Y-H, Lin Y.-T., Lin Y-H, Lin Y.-T., National Chung Hsing University, TW

In the recent decades, titanium dioxide (TiO2) nano-material was received widely attention because of its good chemical stability, low-toxicity, self-cleaning, anti-bacteria and deodorant. However, its photocatalytic activity was limited only by ultraviolte (UV) light irradiation [...]

Novel Membrane Technology for Green Ethylene Production

Balachandran U., Lee T.H., Dorris S.E., Scouten C.G., Marshall C.L., Argonne National Laboratory, US

Today ethylene is produced (approximately 60 billion pounds in 2005 in U.S.A. alone) by thermal cracking of ethane in presence of steam requiring substantial energy input. The equilibrium conversion is thermodynamically limited. Because of direct [...]
