Аннотация:A series of mesoporous Cu-incorporated Al2O3-based catalysts were synthesized via the sol–gelmethod using dodecylamine (DDA) and polyethyleneimine (PEI) as templates. The catalysts were characterizedusing low-temperature N2 adsorption–desorption, X-ray diffraction (XRD), scanning electron microscopy (SEM),H2 temperature-programmed reduction (H2-TPR), and NH3 temperature-programmed desorption (NH3-TPD). ACuO/Al2O3 catalyst prepared by wetness impregnation of commercial Al2O3 was used as a reference sample. All thesamples were reduced and tested in the vapor-phase reductive alkylation of nitrobenzene with methanol (RANM)using a flow-type reactor. With polyethylenimine as a template, the synthesized catalyst possessed ordered cylindricalpores and a specific surface area up to 260 m2/g, whereas the catalyst prepared using dodecylamine had slitpores and a specific surface area of 270 m2/g. The catalytic activity of mesoporous Cu/Al2O3 catalysts in RANM
