Abstract EN
ZrO2-SiO2 mixed oxides were prepared via the sol-gel method.
Photo-assisted deposition was utilized for doping the prepared mixed oxide with 0.1, 0.2, 0.3, and 0.4 wt% of Pt.
XRD spectra showed that doping did not result in the incorporation of Pt within the crystal structure of the material.
UV-reflectance spectrometry showed that the band gap of ZrO2-SiO2 decreased from 3.04 eV to 2.48 eV with 0.4 wt% Pt doping.
The results show a specific surface area increase of 20%.
Enhanced photocatalysis of Pt/ZrO2-SiO2 was successfully tested on photo degradation of cyanide under illumination of visible light.
100% conversion was achieved within 20 min with 0.3 wt% of Pt doped ZrO2-SiO2.
