Titania mesoporous films fabricated by material printing

Thesis deals with the creation of thin layers of a porous titanium dioxide. The solutions for the formation of thin layers were prepared using a solgel method by mixing TTIP, polyethylene glycol of molecular weight 1500 and dimethyl, layers were subsequently printed by material printer to glass substrate and calcinated at 450 °C for 2,5 hours. Optical and SEM microscopy was used to observe structure of individual layers. Samples, that showed the greatest porosity, were subsequently studied by electrochemical measurments and by photocatalytic aktivity determined via hydroxylation of coumarin
