TiO2 Photocatalytic Micro-Channel Reactors Using Capillary Plates

Abstract:

Article Preview

Inner surface of capillary plates (CP) was coated with TiO2 to fabricate a micro-channel reactor with 6-μm diameter. Titania sol was used to coat the surface of channel wall of CP and then it was calcined at 400°C for 4 h. The photocatalytic micro-channel reactors were evaluated by measuring the decomposition rate of methyleneblue (MB) in aqueous solution circulating at the rate ranging from 1.2 to 5.8 cm3 min-1. The TiO2-coated CP showed a larger efficiency in decomposing MB solution, comparing with the previously reported reactor using porous ceramics. The reaction rate increased with the flow rate, while it decreased at higher flow rates for the previous reactor.
