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

Quantum yields (mol of methane/Einstein) for photomineralization of methane, as a function of initial concentration , expressed as mg/L of carbon, and of absorbed power per unit length of lamp (and membrane), expressed as Wcm⁻¹. Quantum yields are expressed as means of values, from experiments in gaseous phase and in aqueous solutions. Photocatalytic membranes used in these experiments did not contain any photopromoting agent.
