초록 |
We propose a novel microfluidic reactor assisted by nanoelectrokinetics for enhancing the photocatalytic reaction. The proposed reactor uses a porous carbon cloth as a substrate for coating TiO2 nanoparticles to improve photocatalytic activity owing to high surface-to-volume ratio, high oxygen permeability from high porosity and activity of carbon-doping source enabling to narrow the bandgap of TiO2. Concentration polarization, nanoelectrokinetic phenomena under the forward potential bias was utilized to improve the mass transfer and increase the contact between photocatalyst and ion/molecules. The resulting high ionic conductance in fluid channel by the applied potential bias caused large potential drop across the photocatalyst film, which can address the problem of the recombination of photo-excited electrons and holes and induce the synergistic effect of photocatalysis and electrocatalysis. |
