    Ni/Mg@Biochar Synthesis And Characterization For The Efficient Reduction Of Pnp
    (Department of Chemistry, NITS, 2022) Majhi, Sarmistha
    Herein, modified Ni/Mg@biochar novel nanaocomposit is synthesised via co-precipitation method and its activity towards the reduction of para-nitrophenol (PNP) has been studied . At first, bamboo biochar was treated with a base. It was further washed and impregnated with the solution of Nickel (II) chloride [NiCl2.6H2O] of 0.6 M and Magnesium sulphate heptahydrate [MgSO4.7H2O] of 0.4 M to obtain novel Ni/Mg@biochar. The structure, composition, surface morphology and reduction analysis were characterised by XRD, EDX, SEM, TEM and UV VIS spectrometer . All the above mentioned characterisation showed the agglomeration of Ni salt and Mg salt over biochar. The catalytic activity of synthesised Ni/Mg@biochar nano composit was studied for the reduction of para-nitrophenol. ). The reduction efficiency of the synthesized nanocomposite showed ~100 % reduction within 28 minutes.
