The efficiency of metal loaded microporous materials, zeolite-Y as catalysts in the ozone initiated oxy-functionalisation of long chained n-alkanes is investigated at moderate temperature (20 ± 1 °C) and pressure conditions (1 atm.). The efficiencies of 0.5% Pd, Ni, V and U loaded microporous zeolite-Y catalysts on ozonation of higher alkanes (n-hexadecane), with respect to the conversion and transformation towards keto products are compared. In the catalysed ozonation, n-hexadecane is converted to 4-, 3- and 2- keto isomers as major products with varied selectivity and % conversions. A plausible mechanism assuming the chemisorption of the substrate molecule on the catalyst surface and further electron transfer between the metal ion loaded on the zeolite support and the active intermediate formed in course of reaction for the ozone initiated oxidation of n-hexadecane with heterogeneous Ni loaded Na-Y zeolite catalyst is proposed.
