“…Much effort has been made to attach metalloporphyrins to solids, namely, adsorption, [9] electrostatic binding, [10] entrapment, [11] polymerisation, [12,13] covalent binding [14][15][16] or axial ligation of metal, [17] but most of them suffer from a reversible binding under work conditions, specially in polar solvents like water or methanol [8], or a fairly low porphyrin contents onto the solid matrix (≈0.02 mmol g −1 ).…”
