Abstract

Bi2Mn2O7 nano-powders were synthesized via a stoichiometric 1 : 1 Bi : Mn molar ratio hydrothermal method at 180 °C for 48 h in a 1 M NaOH aqueous solution. Ultraviolet-visible (UV-vis) spectrum analysis showed that the nanostructured Bi2Mn2O7 powders possessed strong light absorption in the ultraviolet region and the direct band gap energy was obtained from the UV-vis spectrum. The as-prepared nanomaterial exhibited high catalytic activity in the one-pot synthesis of the heterocyclic compounds 3,4-dihydropyrimidin-2(1H)-ones (DHPMs) in Biginelli reaction. Experimental design was used to find the optimized reaction conditions. Reusability of the catalyst was also investigated.
