In this study, an effective and stable Cu2+ incorporated within the lattice of ZIF-8 was hydrothermally synthesized employed as a heterogeneous catalyst for dehydrogenative coupling between 2-aminobenzamide CH3OH. The Cu2+-doped (Cu@ZIF-8) catalysts were firmly characterized using powder X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, transmission photoelectron UV-visible diffuse reflectance spectra, Brunauer-Emmett-Teller techniques to examine their structural, morphological, elemental, optical, surface properties. catalytic efficiency Cu@ZIF-8 investigated in synthesis quinazolinone from CH3OH C1 source with Cs2CO3 base under oxygen atmosphere. Among different catalysts, 30% demonstrated superior activity formation compared pristine ZIF-8, indicating that doping ions provides synergetic effect during reaction. Furthermore, reusability experiments carried out catalyst, observed findings show is maintained up four cycles. structural integrity along morphology chemical structure reused solid also verified, no significant differences fresh solids plausible reaction mechanism proposed.
