Abstract: A highly cross-linked network of carbon fibers was formed during the dilute oxypyrolysis of methane over a silicon carbide surface. Electron microscopy and focused ion beam milling studies demonstrate that the fibers are comprised of a carbon sheath and a silicon oxide core. Examination of surfaces exposed for different periods of time revealed that the growth of the network was a two-step process involving the formation of a silicon oxide micro-wire network, followed by carbon deposition and thickening of the fibers. Secondary reactions within the fibers are proposed which disrupt the internal structure and introduce internal pores. [ABSTRACT FROM AUTHOR] |
