Efficient microfluidic photocatalysis in a symmetrical metal-cladding waveguide

Abstract

In this paper, a symmetrical metal-cladding optical waveguide based microfluidic chip with a self-organized and free-standing TiO₂ nanotube membrane was utilized to perform efficient photocatalysis. The chip has a microchannel bonded with TiO₂ nanotube coated glass. The employment of microfluidic chip for hydrolysis reaction can enable the transfer of mass and photons. Moreover, the incorporation of the double metal-cladding waveguide enhances the light–matter interaction and effectively improves the efficiency of photocatalysis.
