Opis:: TiO2 was surface modified with silver, gold, palladium and platinum ion clusters to improve its photocatalytic activity. The effect of metal content and kind of dopant used during preparation procedure on the photoactivity were investigated. in toluene removal which was used as a model volatile organic compound. Toluene, at the concentration of about 100 ppm, was irradiated over noble metal modified TiO2 using light-emitting diodes (LEDs) in four subsequent cycles.

Opis:: Photocatalysts based on TiO2 co-doped with rare earth metal (RE) and gold nanoparticles have been prepared using a sol-gel method and followed by gold reduction. Specific surface areas of the modified photocatalysts were calculated by the Brunauer-Emmett-Teller method (BET). Diffuse reflectance spectra of the obtained photocatalysts were recorded with a UV-Vis spectrophotometer (DRS UV-Vis). The influence of the type of rare earth metal on photoactivity of Au-RE-TiO2 nanocomposites in model reaction manifested by toluene photodegradation in a gas phase was investigated. The obtained results showed that photodegradation of toluene in the gas phase is possible over Au-RE-TiO2 irradiated by UV or Vis light. The Au-RE-TiO2 photocatalysts relative to undoped TiO2, did not caused an increase of toluene degradation in the air under visible light. The samples doped with Er3+ or Pr3+ presented the highest activity in solar light among of Au-RE-TiO2. It was observed that both metal dopants affected the surface area of TiO2. The Au-RE-TiO2 photocatalysts relative to undoped TiO2 exhibited the absorption properties under Vis light.

Opis:: The article presents results of research work which aim was development of solution for volatile organic compounds (VOCs) removal from vehicle indoor air. VOCs, especially benzene, toluene, and xylene (BTX), are air pollutants responsible for many civilizational diseases because of its carcinogenic and mutagenic properties. Concentration of those substances can be even few times higher in micro atmosphere of vehicle cabin than in other indoor atmospheres [1]. The aim of the scientific cooperation between Dr. Schneider Automotive Polska and the Wroclaw University of Science and Technology (WUST) is research on innovative (international range), product development – photocatalytic reactor characterized by Volatile Organic Compounds, especially BTX removal properties. The BTX reduction effectiveness, caused by photocatalytic reactor application in vehicle ventilation system, was subjected to in-depth analysis. The results showed difference on not only maximal benzene, toluene, and xylene reduction (separately) but also in the pattern of response surface. In some tested parameters, the hazardous compounds (as a BTX sum) were reduced for almost 70%. The photocatalytic reactor seems to be prospective solution for air quality improvement in any vehicle cabin.
