Abstract

VIEIRA, Ricardo et al. Catalytic decomposition of hydrazine over iridium supported on carbon nanofiber composites for propulsion in space: tests under real-life conditions. Quím. Nova [online]. 2005, vol.28, n.1, pp.42-45. ISSN 0100-4042.  https://doi.org/10.1590/S0100-40422005000100008.

The aim of this work is to present the catalytic performance of iridium supported on carbon nanofibers with macroscopic shaping in a 2 N hydrazine microthruster placed inside a vacuum chamber in order to reproduce real-life conditions. The performances obtained are compared to those of the commercial catalyst Shell 405. The carbon-nanofiber based catalyst showed better performance than the commercial catalyst from the standpoint of activity due to its texture and its thermal conductivity.

Keywords : carbon nanofiber; hydrazine decomposition; satellite propulsion.
