Novel macroporous 3D photocatalytic foams for simultaneous wastewater disinfection and removal of contaminants of emerging concern

Autor: V.M. Monsalvo, Angel Encinas, Javier Marugán, Cristina Pablos, Miguel Martín-Sómer, Rafael van Grieken, Ana de Diego

Publikováno v: Chemical Engineering Journal. 366:449-459

A comparative study of the photocatalytic efficiency obtained in water disinfection and the simultaneous removal of micropollutants was carried out by using three different TiO2 photocatalytic materials. The three photocatalysts were immobilized in m

Influence of light distribution on the performance of photocatalytic reactors: LED vs mercury lamps

Autor: Rafael van Grieken, Cristina Pablos, Miguel Martín-Sómer, Javier Marugán

Publikováno v: Applied Catalysis B: Environmental. 215:1-7

UV LED technology has revolutionized the photocatalytic processes due to their significant advantages over traditional mercury-based illumination sources, specifically its higher energy efficiency. However, the use of LED also introduces important ch

Influence of stereospecificity and molecular weight on mechanical properties of iso-syndio-polypropylene obtained by combination of metallocene catalysts

Autor: Ester Lopez-Moya, Rafael van Grieken, Alicia Carrero, Beatriz Paredes

Publikováno v: European Polymer Journal. 90:183-194

Polypropylene with special properties can be obtained using two supported metallocene catalysts of different stereospecificities: rac-Me2Si(2-Me-benz[e]Ind)2 ZrCl2 [CAT-B] as an isotactic catalyst precursor and Ph2C(Cp)(9-Flu)ZrCl2 [CAT-C] as a syndi

Photocatalytic Disinfection and Removal of Emerging Pollutants from Effluents of Biological Wastewater Treatments, Using a Newly Developed Large-Scale Solar Simulator

Autor: Rafael van Grieken, Javier Marugán, Ruud Timmers, Karine K. Philippe

Publikováno v: Industrial & Engineering Chemistry Research. 55:2952-2958

The reuse of sewage water treatment is becoming a priority, especially in arid regions, where water is scarce. However, there is increasing concern about the presence of emerging micropollutants refractory to the conventional treatments in wastewater
