Selective hydrogenation of nitrobenzene to aniline over LaNiO3

Perovskite LaNiO₃ prepared by the glycine–nitrate method was studied by XPS, XRD and SEM-EDS. This substance was tested as the catalyst in the hydrogenation of nitrobenzene to aniline in ethanol (150 °C, 1.5 MPa H₂). The selectivity for aniline was 95.6% with a conversion of 98.7%. According to XPS data, La and Ni do not change their electronic state in the course of the reaction.
