A photocatalytic microreactor with immobilized titanium dioxide as photocatalyst and illuminated by UV-A light emitting diodes was constructed and tested for the degradation of the model substance 4-chlorophenol. The microreactor consisted of 19 channels with a cross-section of approximately 200 mum x 300 mum. Intrinsic kinetic parameters of the reaction could be detern-lined and mass-transfer limitations for the employed operating conditions could be excluded by calculating appropriate Damkbhler numbers. Photonic efficiencies for the degradation of 4-chlorophenol are provided. The illuminated specific surface of the microstructured reactor surpasses that of conventional photocatalytic reactors by a factor of 4-400. (C) 2004 Elsevier B.V. All rights reserved.
