High yield, controlled synthesis of graphitic networks from dense micro emulsions

15 September, 2014 - 04:54

Chem. Commun., 2014, 50,11848-11851
DOI: 10.1039/C4CC05455E, CommunicationE. Negro, M. Dieci, D. Sordi, K. Kowlgi, M. Makkee, G. J. M. Koper
We propose a new synthesis method to produce hyper-branched carbon nano structures that we call carbon nano networks. These porous, graphitic materials directly grow into a networked structure, do not require the use of an inorganic support, and can be tailored by experimental conditions to better suit their application.
