Reactivity of the first transition row metallocenes in thermal decomposition reaction

Carbon nanotube reactor: Ferrocene decomposition, iron particle growth, nanotube aggregation and scale-up

“…c CN A k s , where k s ¼ 1:43 Â 10 7 e À1:71Â10 5 ðJ=molÞ=RuT m s À1 , which was measured by Dyagileva et al (1975). However, if we compare homogeneous with surface ferrocene decomposition, using the maximum number of particles N p $ N A M À1 c C s and the initial iron particle diameter, d 0 , we obtain the ratio pN A C s M À1 c d 2 0 k s =k c 5 1 for surface to homogeneous reaction.…”

Carbon Nanotubes Filled with Ferromagnetic Materials

“…The typical setup for the SSCVD method is shown in Figure 2. In the first temperature zone (T${}_{pre}$ ≪ T${}_{reac}$) the metallocene powder is positioned in a quartz boat and is directly sublimated at a compound specific temperature (e.g., for ferrocene in the temperature range between 100 and 200 ° C) [34,35]. The metallocene vapor is transferred by a controlled argon, hydrogen or nitrogen flow (or mixtures of them) into the second temperature zone (T${}_{reac}$) where the decomposition of the metallocene and the growth of the filled carbon nanotubes occurs.…”

Graphene Layers‐Wrapped Fe/Fe5C2 Nanoparticles Supported on N‐doped Graphene Nanosheets for Highly Efficient Oxygen Reduction

“…Only two main peaks located at about 1600 cm −1 (CN) and 1300 cm −1 (CN) are observed in GL-Fe/ Fe 5 C 2 /NG-650, confirming the formation of carbon materials. when treated at a temperature higher than 550 °C, [45] and the NH 2 /NH groups in g-C 3 N 4 are so unstable that they can be reduced by H 2 without changing the main structure of g-C 3 N 4 . XPS inspection also confirms the denitrogen process.…”
