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 7
Quantum efficiencies (mol/Einstein)
of methane, extrapolated by (17), at infinite concentration of
substrate, relative to measurements carried out in the gaseous phase, as a
function of absorbed power per unit length of irradiated photocatalytic
membrane, expressed as Wcm−1. Photocatalytic membranes used in the
relative experiments contained the photopromoter (see Experimental) at a
concentration corresponding to 3.0 mol/mol % of vanadium with respect to
titanium present as main photocatalyst.
