Preparation and characterization of near-stoichiometric silicon carbon fibres

Abstract

Near-stoichiometric SiC fibres (CVC-S fibres) were successfully prepared by pyrolysing chemical-vapour-cured polycarbosilane fibres under hydrogen and subsequent heat treatment in inert atmosphere at 1500 °C.

Monitoring Electron Flow in Nickel Single-Atom Catalysts during Nitrogen Photofixation

“… Meanwhile, the peak located at 282.3 eV in the C 1 s spectrum was assigned to a metal–C bond, suggesting the decoration of the rGO substrate by Ni species and CeO 2 nanoparticles (Figure S7D). , To further explore the local structure of CeO 2 /Ni-G, hard XAS measurements were conducted. In the X-ray absorption near-edge structure (XANES) spectrum of the Ce L 3 -edge for CeO 2 /Ni-G, the peak located at 5726.1 eV was assigned to Ce 3+ , and two peaks at 5730.3 and 5738.2 eV corresponded to Ce 4+ species .…”
