n conclusion, we have reported an efficient and green catalytic process based on amine functionalized inorganic/organic biocomposites for the hydrogenation of nitroarenes and carbonyl compounds using environment friendly hydrogen at room temperature in benign reaction media. The operational simplicity, stability, reusability of catalyst and above all, the yield of amines and alcohols with high selectivity in short reaction times and with zero effluent discharge make it an environmentally acceptable and greener alternative for the reduction of nitroarenes and carbonyl compounds.
