TiO2 thin films were synthesized by using Chemical Vapor Deposition (CVD) method on different substrates, such as glass, aluminium foil , and ceramic. The samples had been characterized by microscopy analysis, SEM, and EDS. The results show that TiO2 thin films were successfully fabricated and TiO2 nanocrystals with size of 50-100 nm loaded uniformly on surface of different substrates.

Silver nanoparticles with the diameter of 5 – 10 nm were successfully deposited on TiO2 nanowires by a facile and low-cost photoreduction method in alkaline solution under UV irradiation. The mutual coordination between light irradiation and NH4OH reduction gives rise to the formation and decoration of the Ag nanoparticles on the surface of TiO2 nanowires.

In this study, photocatalysis was applied to degrade methyl orange (MO ) and methylene blue (MB) pollutants using nanoparticles (i.e., Fe2O3, Mn2O3, Fe2O3 – Mn2O3). During photodecomposition, formed intermediates due to the incomplete reaction of pollutions and hydroxyl radical were investigated using the ions trap technique.

In this study, pellets of iron alumina pillared bentonite (PFeAPB) were prepared by dispersing iron ions on alumina pillared bentonite pellet. Catalyst activity and lifetime were investigated via efficiencies of Methyl Orange (MO) decolorization and Chemical Oxygen Demand (COD) removal, a typical dye type of textile wastewater. Characteristics of the PFeAPB catalyst were examined by X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) surface area, and X-ray fluorescence (XRF).

The result shows that the synthesized BiNbO4 for the optimized sample have size that smaller than 70 nm. Also decomposing methyl orange solution illumination for 2 hours at a rate of 0.25 g/l BiNbO4 turns liquid were capacity ≈ 99 %. After the 3rd time of regeneration the BiNbO4 also able to be used by evidence of 97.20 % of removing methyl orange.

TiO2 thin film with nanoporous structure are prepared from colloidal suspension containing polyethylen glycol (PEG) via Sol-Gel method. The effect of PEG addition to the precursor solution on the surface structures and photocatalytic activity of the resultant thin films are studied. The larger the amount of PEG added to to the precursor solution, the larger the size and number of pores produced in the resultant films when PEG added to the gel films decomposed completely during heat-treatment.
