✦ Synopsis

Catalytic activity of some transition metal complexes derived from crosslinked styrene-divinylbenzene copolymer with Ž . spacer containing a-nitroso-b-naphthol as a functional group Ps-ANBN have been used for the decomposition of hydrogen Ž . peroxide H O . The decomposition of H O was investigated by measuring evolution of oxygen at different time 2 2 2 2 intervals. Kinetic and thermodynamic parameters have been evaluated. Various metal complexes were used to study the Ž . effect of the nature of metal ion on decomposition of H O . Scanning electron microscopy SEM have been used to study 2 2

the morphological variation between Ps-ANBN and Ps-ANBN-Cu II . The Ps-ANBN-Cu II is found to be thermodynamically more stable than Ps-ANBN.
