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 4

Quantum efficiencies (mol/Einstein), extrapolated by (14) (see Experimental), at infinite concentration of substrate, for methane in air (red dots) and in aqueous solution (blue dots), as a function of absorbed power per unit length of irradiated photocatalytic membrane, expressed as W ( b ) cm−1. Photocatalytic membranes used in the relative experiments did not contain any photopromoting agent.
