The Formation of Pyrolytic Carbon on a Nickel Sheet

Abstract

Pyrolytic carbon films were deposited on nickel sheets by pyrolysis of benzene at 1000°C. The surface morphology and the degree of graphitization of the deposited carbon films depended on the benzen concentration of the supplied gas. A large amount of nickel was extruded from the nickel substrate to the surface of the carbon film at a certain concentration of benzene.

Pyrolytic Carbon Films with Tunable Electronic Structure and Surface Functionality: A Planar Stand‐In for Electroanalysis of Energy‐Relevant Reactions

“…Thin films of “pyrolytic carbon” (pyC) are readily generated by chemical vapor deposition at moderate pyrolysis temperatures (900–1300 °C) . Among the various hydrocarbon precursors that have been used, benzene is a convenient source for bench‐scale deposition and yields high‐quality pyC films . We recently reported on the use of benzene‐derived pyC films on planar fused‐silica substrates as a means to investigate heterogeneous electron transfer of redox probes.…”

“…[39,40] Among the various hydrocarbon precursors that have been used, benzene is a convenient source for bench-scale deposition and yields high-quality pyC films. [41][42][43][44][45] We recently reported on the use of benzene-derived pyC films on planar fused-silica substrates as a means to investigate heterogeneous electron transfer of redox probes. When modified by electrolessly depositing nanoparticulate ruthenium oxide, the RuOx-decorated pyC mimicked the fast rates of Pt, not the far slower rates of carbon.…”
