Sulfamic acid incorporated HKUST-1: a highly active catalyst and efficient adsorbent

摘要: Herein we introduce an effective approach for incorporating sulfamic acid (SA) into HKUST-1. The synthesized materials have been characterized using XRD, XPS, BET, FT-IR, SEM, EDX and TEM. X-ray diffraction pattern of SA@HKUST-1 is analogous to that parent HKUST-1 in line shape d-spacing, proving chemical modification could be obtained without damage structural solidity. XPS spectra confirmed successful sulfonation, due the single S 2p peak being attributable SO3H groups at 168 eV. Catalytic efficiency was studied 7-hydroxy-4-methyl coumarin 3,4-dihydropyrimidinone synthesis it found highly dependent on amount SA loaded over Moreover, adsorptive removal activity some common organic inorganic pollutants from water has studied. To fully understand adsorption process, effects initial dye concentration, pH solution, adsorbent dosage, contact time temperature process were successfully Under optimum conditions 10 wt% able reach maximum capacity Pb2+ (298 mg g−1) Malachite green (290 g−1). Hopefully, this will facilitate research improving prospective use MOFs future applications.
