Abstract

Cu(II) histidine or Cu(II)-diethylene-triamino-mu-imidazolato-Zn(II)-tris-aminoethylamine triperchlorato complexes were prepared and immobilised in/on porous matrices (montmorillonite and silica gel) via (i) adsorption/hydrogen bonding, (ii) electrostatic forces or (iii) grafting with covalent bond. It was found that immobilisation increased catalytic activity and catalyst lifetime in the decomposition reaction of hydrogen peroxide relative to the matrix-free complexes. The immobilised materials were characterised by experimental and computational methods.
