ABSTRACT: In this study, two Cu-based catalysts with and without N doped carbon matrix, named N-Cu/CuO/C
and Cu/CuO were synthesized via calcination of melamine-cupper acetate complex
and cupper acetate at 500°C under an inert atmosphere. The catalysts were
characterized by X-ray powder diffraction (XRD), Field Emission Scanning
Electron Microscope (FESEM), and CHNS elemental analyzer. The catalytic activity of both catalysts was
evaluated through the NaBH4 associated reduction of
commercial textile dye named reactive black 5 (RB5). The kinetics of the
reduction of reactive black 5 was also described by the pseudo-first-order
kinetic equation. For the studied reduction, N-Cu/CuO/C exhibited enhanced
catalytic activity both in conversion and kinetics (97% conv. in 315 sec)
compared to that of by Cu/CuO/C (25% conv. in 1500 sec). Besides, N-Cu/CuO/C
also demonstrated good reusability up to four consecutive cycles.
