Development of intensified flat-plate packed-bed solar reactors for heterogeneous photocatalysis

3D-printing design for continuous flow catalysis

“…In this direction, Texeira and coworkers have developed a 3Dprinted microreactor using acrylonitrile butadiene styrene by fused filament fabrication. Such reactors were used for the degradation of acetaminophen in aqueous solution, using zinc oxidebased catalysts and sunlight-type irradiation [68]. Combining photocatalysis and 3D printing constitutes a thrilling possibility to expand the applications of photocatalysis and facilitate photoreactor designs.…”

High power illumination system for uniform, isotropic and real time controlled irradiance in photoactivated processes research

“…Approaching the light source to the reaction vessel increases the irradiation levels, but compromises uniformity. The problem can be alleviated using multiple light sources, like LED strips and arrays [24] , [33] , [34] , [35] , [36] . It has been shown that illumination uniformity depends critically on the size of the sample, the distribution of light sources in the array and on the array-sample distance [24] , [37] , [38] and it is very poor if light sources are too close to the sample surface.…”
