Information × Registration Number 0210U006244, 0109U004500 , R & D reports Title Tailored synthesis of functional materials based on mesoporous oxide films on anodic alumina for optic design and ecological photocatalysis popup.stage_title Head Kartel N.T., к.х.н. Registration Date 23-06-2010 Organization Chuiko Institute of Surface Chemistry of NAS of Ukraine popup.description2 Formation of mesoporous structure takes place in TiO2 films on the glass with particle size in the range of from 5 to 50 нм as the increase of particle size (10 nм) of TiO2 particles is observed on the porous anodic alumina with cell diamentr 100 nм and pore diamentr 60-80 nм while the membrane is about 130 microм.TiO2/ZrO2/SiO2, TiO2/ZrO2/SiO2/Ag and TiO2/ZrO2/SiO2/Au films synthsized by sol-gel method. The thickness of the films containing gold nanoparticles is 120 nм and refractive index is 1,92 . Modification of the film by Au nanoparticles leads to the increase of surface polarization confirming the growth or reorganization of nanocrystals and the decrease in the distance between them with the layer increas . Deacrease of the thickness of one laeyr and band-gap of TiO2/ZrO2/SiO2/Au film caused the formation of the increase of TiO2 particle size in the presence of gold nanoparticles . TiO2/ZrO2/SiO2 films modified by Au or Ag nanoparticles that are homogeneously distributed on the surface with the forms like tube, pyramide and sphere with the size of 20 - 16 nм. The particle size of Ag nanoparticles in TiO2/ZrO2/SiO2/Ag films is 30-32 nм.
