  Because of the tremendous structural diversityof ionic liquids (ILs), simple transfer of observations performed for one IL used for IL-TiO2 preparation on different samples is not possible. Therefore, four ionic liquids, all containing distinct nitrogen-bearing organic cations (pyridinium, pyrrolidinium, ammonium, imidazolium), were used for the first time for the preparation of IL-TiO2 composites. The role of the individual IL...

  - APPLIED SURFACE SCIENCE - Year 2017

  A series of microemulsion (ME) system, constituted by different water to surfactant molar ratios (Wo) and oil to surfactant mass ratios (S), have been applied for Pd-TiO2 preparation. The effect of ME properties on the morphology of Pd nanoparticles formed at TiO2 surface and an effect of Pd size and distribution on the surface and photocatalytic properties of Pd-TiO2 were investigated. Microemulsion systems were characterized...

  The effect of the ionic liquid’s (IL) anion type ([BIMIM][X], where X= [Br], [PF6] or [OctSO4]) and content on the morphology, surface properties and photoactivity of TiO2 obtained by solvothermal method has been systematically investigated. Our results revealed that the presence of [Br], [OctSO4] anions favors formation of anatase phase, while presence of [PF6] anion causes formation of mixture of anatase and Ti(OH)PO4 phases....

  W pracy przedstawiono wyniki badań fermentacji metanowej biomasy kapusty białej i osadu nadmiernego pobranego z oczyszczalni ścieków Saur Neptun Gdańsk S.A. Proces fermentacji prowadzono w warunkach mokrych, w sposób quaziciągły, w temperaturze 37°C. Zaobserwowano, że poddając fermentacji beztlenowej wsad zawierający kapustę białą oraz osad nadmierny można uzyskać biogaz o średnim składzie 50% metanu i 50% ditlenku węgla. Podczas...
