摘要

Metal-organic framework (MOF)–based composites have gained significant interest in various fields, particularly in catalysis and environmental remediation. In this study, CuBTC was immobilized on amine-functionalized alumina supports (1,2-en/Al2O3@CuBTC, 1,4-en/Al2O3@CuBTC, 1,6-en/Al2O3@CuBTC, and arg/Al2O3@CuBTC), and their performance was systematically evaluated for (i) adsorption and oxidative degradation of organic dyes-methylene blue (MB), rhodamine B (RhB), methyl red (MR), and methyl orange (MO), and (ii) the synthesis of 1,4-disubstituted-1,2,3-triazoles via click reaction in water. Among the four materials, 1,6-en/Al2O3@CuBTC exhibited the highest catalytic efficiency, attributed to its larger specific surface area (~ 524 m2 g⁻1, highest among the series). This composite achieved rapid dye removal with exceptional adsorption capacity for four dyes, i.e. MB (96.85% in 15 min), MR (96.80% in 20 min), RhB (92.11% in 35 min), and MO (95.45% in 20 min), and oxidative degradation efficiencies ~ 99%, without generating secondary pollutants. Moreover, 1,6-en/Al2O3@CuBTC exhibits excellent catalytic activity for the synthesis of triazoles using water as an environmentally friendly solvent. Clinical trial number: not applicable.
