TiO₂ sol was produced by the sol-gel method through the hydrolysis and the aging of tetrabutyl titanate and the TiO₂ film was obtained by dipping and uniform lifting of the acid-treated and ultrasound-treated clean glass slides into the TiO₂ sol followed by aging, drying, and calcination. The effect of the hydrolysis control agents to the formed sol was researched and the crystalline state, the...

A novel Zr,Ce-TiO2/SiO2 nanocomposite thin film was successfully prepared with various amounts of Zr4+ and Ce4+ as codopant ions for self-cleaning applications. A thin film was coated on a tile substrate by dip-coating and porous Zr,Ce-TiO2/SiO2 was obtained after heat treatment for 2 hours at 500 °C. The SEM images an...

Self-cleaning fabrics can be developed based on introducing two mechanisms of superhydrophobicity and photocatalytic activity to conventional fabrics. However, there are some downsides such as inefficiency superhydrophobic coatings against oily contaminants low effectiveness surface treatments under visible light which have restricted the widespread applications these functional products. This ...

A photocatalytic Ce-Y-ZrO 2 /TiO ultrafiltration membrane was successfully prepared on a ZrO /SiC support by modified sol-gel process. The top active layer is µm thick, uniform and defect-free. presented molecular weight cut-off (MWCO) of 19 kDa (equivalent to pore size 6 nm) high pure water permeability, 160 Lm ?2 h ?1 bar . hydrophilicity negative surface charge the favoured its great retenti...

Bu çalışmada eğirme esnasında katkılanan TiO2 miktarına bağlı olarak, polietilen tereftalat liflerde (PET) kendi kendini temizleme özelliği incelenmektedir. Lifler eğirildikten sonra dokunarak siyah çay, kahve, vişne suyu ve ketçap ile lekelenmiştir. Ardından numune kumaşlar gün ışığı Xenon lamba gibi farklı ışık koşullarına maruz bırakılarak lekelerin zamanla giderimi incelenmiştir. Ayrıca, ür...

Conventional photocatalysts are primarily stimulated using ultraviolet (UV) light to elicit reactive oxygen species and have wide applications in environmental and energy fields, including self-cleaning surfaces and sterilization. Because UV illumination is hazardous to humans, visible light-responsive photocatalysts (VLRPs) were discovered and are now applied to increase photocatalysis. Howeve...
