Kinetics of photocatalytic oxidation of methane, ethane, and n-heptane, to yield intermediates, and photomineralization of intermediates, to yield carbon dioxide and water, was studied in the gaseous phase, at 308[+ or -]2 K, by a laboratory-scale photoreactor and photocatalytic membranes immobilizing 30 [+ or -] 3wt.% of Ti[O.sub.2], in the presence of aerosolized stoichiometric hydrogen peroxide as oxygen donor, and at a relative humidity close to 100%. The whole volume of irradiated solution was 4.000[+ or -]0.005 L, the ratio between this volume and the geometrical apparent surface of the irradiated side of the photocatalytic membrane was 3.8[+ or -]0.1 cm, and the ...
