Influence of Irradiance, Flow Rate, Reactor Geometry, and Photopromoter Concentration in Mineralization Kinetics of Methane in Air and in Aqueous Solutions by Photocatalytic Membranes Immobilizing Titanium Dioxide

Figure 8

Quantum efficiencies T i O 2 (mol/Einstein) of methane, extrapolated by (17), at infinite concentration of substrate, relative to measurements carried out in the gaseous phase, and corresponding to an absorbed power per unit length of irradiated photocatalytic membrane, expressed of 4.0 W T i O 2 cm−1, as a function of mol/mol % of vanadium, used as photopromoter in the photocatalytic membranes, with respect to titanium present as main photocatalyst.
