摘要: In this study, a micro-photoreactor with catalyst-immobilized micro-channels was designed and fabricated using CO2 laser as simple inexpensive technique. The is composed of an array micro-channels, quartz plate, UV-LEDs. the dimension 400 µm width, 50 µm depth, 80 cm length were inscribed on flat plate poly(methyl methacrylate) (PMMA). illuminated specific surface area for micro-reactor calculated to be 25000 m–1. To examine performance miniaturized photoreactor, photocatalytic degradation 4-Nitrophenol refractory pollutant investigated. effects operational variables studied. Higher obtained low flow rates, high light intensities, long lengths, inlet concentrations. Also, examined in presence different types TiO2 catalysts...
