Photocatalytic thermodynamic efficiency factor

Reactor efficiencies can be evaluated for the photocatalytic conversion of water pollutants (Chapter VI) using a number of efficiency factors such as the Electrical Energy per Order (EE/0) (Notarfonzo and McPhee, 1994), the quantum yield, the quantum efficiency (Bockelmann etal., 1993 Valladares andBolton, 1993) and the photocatalytic thermodynamic efficiency factor (PTEF) (Serrano and de Lasa, 1997). 

Serrano and de Lasa (1997,1999) evaluated the efficiency of the photocatalytic conversion of organic pollutants using a PTEF (Photocatalytic Thermodynamic Efficiency Factor). This factor is based on both photochemical and thermodynamic principles. 

The Photochemical Thermodynamic Efficiency Factor (PTEF) is an energy ratio equating the energy used to achieve the photocatalytic conversion of organic molecules over the energy absorbed by the photocatalyst. This parameter was first introduced by Serrano and de Lasa (1997) and evaluates the performance of photocatalytic reactors on a thermodynamic basis.
