    • Abstract


      A procedure for practical synthesis of CuNPs from CuSO4.5H2O is established, under appropriatereaction conditions, using rice (Oryza sativa) as an economic source of reducing as well as a stabilizing agent.Optical and microscopic techniques are employed for the characterization of the synthesized CuNPs and thesizes of the particles were found to be in the range of 8 ± 2 nm. The nanoparticles are used as a catalyst forchemoselective reduction of aromatic nitro compounds to corresponding amines under ambient conditionsand water as a reaction medium.

    • Graphical Abstract


      CuNPs are synthesized using hydrolysed rice and used as catalyst for chemoselective reduction of nitroarenes to their corresponding amines in water.
