Carbon Hollow Nanospheres from Chlorination of …

2018-7-25 · The chlorination of ferrocene at 900 °C yields very interesting carbon hollow nanospheres (CHNSs) with diameters of ∼50−150 nm and ∼12−25 nm thick walls. X-ray energy-dispersive spectroscopy shows no traces of chlorine or iron and the π*/σ* ratio of the carbon bonding was quantified by electron energy-loss spectroscopy with 80% sp2 (100% sp2 for pure graphite).

Etching of silicon carbide by chlorine - ScienceDirect

The reaction of Cl 2 with polycrystalline β-silicon carbide was studied by the modulated molecular beam-mass spectrometric detection method. The temperature range was 300–1000 K and beam intensities between 10 16 and 10 17 /cm 2 s were employed. The sole silicon-bearing gaseous product was SiCl 4, which was produced with a maximum reaction probability of 5 × 10-4 at 740 K.
