▎ 摘  要

This study focuses on the synthesis of an exclusive and extremely effective heterogeneous nanocatalyst via the decoration of copper(II) complex bearing 5-aminotetrazole ligand onto graphene oxide nanosheets (GONS) surface the carboxylic groups of which have been activated by thionyl chloride (SOCl2). The structural features of this catalyst (GONS-aminotet-Cu(II)) were investigated by FESEM, TEM, HRTEM, STEM, TG-DTG, FTIR, XRD, and EDS. The catalytic prowess of the GONS-aminotet-Cu(II) nanocatalyst was evaluated in the 4-nitrophenol (4-NP), Rhodamine B (RhB), methylene blue (MB), nigrosin (NS) and congo red (CR) reduction with NaBH4. The surface nature of GONS changed after immobilization of the complex, causing a notable increase in the catalytic prowess. The results displayed that the nanocatalyst can be reused six successive times, demonstrating high recyclability and excellent chemical stability.
