Abstract: In this study, two Cu-based catalysts with and without N doped carbon matrix, named N-Cu CuO Cand Cu CuO were synthesized via calcination of melamine-cupper acetate complexand cupper acetate at 500°C under an inert atmosphere. The catalysts werecharacterized by X-ray powder diffraction (XRD), Field Emission ScanningElectron Microscope (FESEM), and CHNS elemental analyzer. The catalytic activity of both catalysts wasevaluated through the NaBH4 associated reduction ofcommercial textile dye named reactive black 5 (RB5). The kinetics of thereduction of reactive black 5 was also described by the pseudo-first-orderkinetic equation. For the studied reduction, N-Cu CuO C exhibited enhancedcatalytic 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 Calso demonstrated good reusability up to four consecutive cycles.
