transform-infrared. The catalytic activity of Cu/MWCNT-GAA@Fe3O4 was investigated in 1,3-dipolar cycloaddition and condensation reactions in water. The results showed a wide range of 1,2,3-triazoles and bis(indolyl)methanes were synthesized with good to excellent yields in a short time. The nanocatalyst could be recovered by applying an external magnetic field, which resulted in easy separation of the catalyst
