Reduction of oxidized Fe(100) by hydrogen

Structure and Surface Chemistry of Industrial Ammonia Synthesis Catalysts

“…The apparent activation energy is 59 ± 4 kJ/mole [134]. The reaction proceeds via the dissociative chemisorption of Hz [134]. For this reason it is not unexpected that the reaction becomes quite inhibited by the presence of a monolayer of 0* [134].…”

“…The apparent activation energy of the reaction is 59 ± 4 kllmole [134]. The transport of 0 to the surface is fast compared to the surface reaction [134].…”

“…For Fe (1 00) this reaction has been studied at 473 and 673 K at 2· 10 -z torr of Hz [134]. The apparent activation energy is 59 ± 4 kJ/mole [134].…”

“…The reaction proceeds via the formation of H* [134]; no reaction is detected if the surface is completely covered by 0* initially [134]. The apparent activation energy of the reaction is 59 ± 4 kllmole [134].…”

“…The reduction of chemisorbed 0* on Fe(100) by Hz has been studied by Augeer electron spectroscopy and LEED at 473 and 673 K [134]. The reaction proceeds via the formation of H* [134]; no reaction is detected if the surface is completely covered by 0* initially [134].…”
