Synthesis, characterisation and reactivity of Cu(II) amine complexes supported on an inorganic ion exchanger, zirconium molybdate

Abstract

Cu(II) amine complexes have been supported onto the surface of an inorganic ion exchanger, zir-conium molybdate. The coordination behaviour of these complexes bound to zirconium molybdate have been studied by TGA, DSC, FTIR, ESR and reflectance spectra. The catalytic activity has been studied through the disproportionation of hydrogen peroxide. The energy of activation (<em>E</em>_a)<em>, </em>free energy of activation (<img src='http://www.niscair.res.in/jinfo/delta.gif' border=0> <em>G</em>^≠), free enthalpy of activation (<img src='http://www.niscair.res.in/jinfo/delta.gif' border=0> <em>H</em>^≠) and free entropy of activation (<img src='http://www.niscair.res.in/jinfo/delta.gif' border=0> <em>S</em>^≠) have also been calculated.
