Abstract
Heterogeneous nanocatalyst demonstrate excellent catalytic activity for the
hydrogenation/reduction of nitro-aromatics, carbonyls, alkenes/alkynes in the presence
of different reductants such as NaBH4 and H2 using various solvents such as ethanol,
methanol, dioxane, THF, and water, as green solvents. Earth-abundant coordinating
elements such as Pd, Pt, Fe, Cu, Co, Ag, Au, and Ni, elementary synthesis, short time
reactions, high selectivity, mild reaction conditions, and reusability of nanocatalyst for
at least 4-5 cycles without any loss in catalytic activity, are some priorities for the
hydrogenation reactions using nanocatalyst.
