Abstract
article i nfo Colloidal solution of nickel(0) in carboxymethyl cellulose showed good catalytic efficiency in hydrogena- tion of aromatic nitro compounds, as well as aliphatic and aromatic ketones in aqueous medium yielding the respective aromatic amines and alcohols in excellent yield along with moderate to good reusability of the catalyst. The catalyst was isolated and characterized by powder XRD, EDX, SEM and TEM studies. The active phase of the catalyst consists of nickel nanoparticles entrapped in carboxymethyl cellulose (Col-Ni-CMC Nps). The ecofriendly synthesis was performed in water at room temperature by NaBH4 reduc- tion of nickel chloride in the presence of sodium carboxymethyl cellulose (CMC).
