Enhanced utilization through immobilization

Enhanced Utility of Polysaccharidases through Chemical Cross-Linking and Immobilization... 

When a PMR equipped with a photocatalytic membrane with photoactive skin layer was appfied for gas phase reactions, an improvement in the efficiency of decomposition, compared to a conventional photocatalytic reactor with T1O2 film immobilized on a non-porous support, was observed (Tsuru et al., 2003). In the case of the photocatalytic reaction conducted in the PMR, all reactants permeate through the pores of the 1102 active layer, which results in more effective contact between the reactants and the photoactive I1O2 surface. Application of a membrane allows control of the residence time of the reactants, thus improving the reaction rate. Moreover, the transport of organic compounds to the IIO2 surface is enhanced by forced convection in addition to transport by diffusion, and a larger surface area could be utilized for the photocatalytic reaction when conducted in the PMR.
