被撤回的出版物: Mesoporous multiwalled carbon nanotubes as supports for monodispersed iron-boron catalysts: improved hydrogen generation from hydrous hydrazine decomposition (Retracted article. See vol. 8, pg. 6908, 2020)

Multiwalled carbon nanotube supported iron-boron catalysts (Fe-B/MWCNTs) were developed via the chemical reduction of aqueous sodium borohydride with iron chloride for hydrolysis of hydrous hydrazine (N2H4). The effects of loading, N2H4 concentration, reaction temperature and supporting materials on the as-prepared Fe-B/MWCNTs were investigated. A high H-2 generation rate of 34.2 L h(-1) g(-1) catalyst for the 9.86 wt% Fe-B/MWCNTs is achieved with 97.0% H-2 selectivity at room temperature. Furthermore, the hydrolysis reaction is zero order with respect to N2H4 concentration in the range 0.1-5 mol L-1, and the activation energy is 46.7 +/- 1.3 kJ mol(-1) for 9.86 wt% Fe-B/MWCNTs. The 9.86 wt% Fe-B/MWCNTs are stable catalysts for N2H4 hydrolytic dehydrogenation as they provide 114 480 total turnovers in 30 h. The improved performance of Fe-B/MWCNTs is a promising step towards the application of N2H4 as a chemical hydrogen storage material.
