Název v původním jazyce

Influence of calcination temperature on the photoelectrochemical and photocatalytic properties of porous TiO2 films electrodeposited from Ti(IV)-alkoxide solution

Popis výsledku v původním jazyce

TiO2/benzoquinone hybrid films have been electrodeposited anodically from basic Ti(IV)-alkoxide solutions containing hydroquinone. The films were calcined at different temperatures between 350 and 550 degrees C and investigated in view of applications asphotocatalyst and in dye-sensitized solar cells. Thermogravimetry analysis, differential thermo analysis, in situ X-ray diffraction, and transmission electron microscopy show the removal of the benzoquinone and starting crystallization of the TiO2 between 350 and 400 degrees C, followed by a further increase in the crystallinity and particle size with increasing calcination temperature, while the specific surface area is decreased due to an increasing pore size as confirmed by Kr adsorption measurements. In dye-sensitized solar cells, the higher crystallinity leads to an improved performance mainly due to improved adsorption of sensitizer dyes up to calcination temperatures of 500 degrees C, ...
