It was found that the use of sodium carbonate as an additive substantially reduced the extent of dehydrohalogenation in the case of monometallic, 1% Pt/C catalyst, to give the highest selectivity of 96% to m-CAN. Ni-Pt bimetallic catalyst although showed almost complete selectivity (&gt;99%) to m-chloroaniline; its activity was several fold lower than that of 1% Pt/C Na2CO3 system. However, compared with Ni monometallic catalyst, bimetallic Ni-Pt showed higher activity and selectivity due to the presence of electron rich surface metallic Pt stabilized by Ni having lower ionization potential compared with Pt.</p>1 aMane, Rasika, B.1 aPotdar, Aparna, S.1 aNadgeri, Jayprakash, M.1 aBiradar, Narayan, S.1 aRode, Chandrashekhar, V.  uhttps://library.ncl.res.in/content/selectivity-tuning-options-hydrogenation-m-chloronitrobenzene-m-chloroaniline-over-mono-0
