Abstract. Strontium was introduced to modify CeO2–ZrO2 mixed oxides (CZ) by two methods, coprecipitation (CZS) and impregnation (SCZ). Structural and textural characterizations revealed that Sr could retard the sintering of oxide particles and restrict the phase segregation during the hydrothermal ageing treatment. Specifically, the impregnation method brought about a more satisfying ther…
Abstract. Visible-activated TiO2 photocatalysts were prepared by surface modification to TiO2 with different isocyanates, including conjugated structured Tolylene-2,4-diisocyanate (TDI) and unconjugated structured m-Xylylene diisocyanate (m-XDI). These two isocyanates could be anchored on the TiO2 surface via p-conjugated chemical bonds of –NHCOOTi, which were formed through the reaction …
