Aims and Objective: Ionic liquids are a suitable medium for stabilization and
preparation of catalytic systems.
Materials and Methods: The two-dimensional (2D) ZnO/Fe3O4 nanocomposites were synthesized
using ionic liquid [OMIM]Br as a stabilizer and soft template. The nanocomposites were
characterized via FTIR, XRD, VSM and SEM analysis.
Result: The catalytic activity of these composites was evaluated using a multicomponent reaction
of primary amines, acetylacetone, and 2-bromoacetophenone.
Conclusion: 2D ZnO/Fe3O4 as a recyclable and green catalyst showed excellent catalytic
performance for the preparation of poly-substituted pyrroles.
