“…The addition of acetyl acetone served as a ligand for titaniumchelating in order not to produce TiO 2 precipitate which characterized by the change of sol to yellow colour. Ethanol served as controlling the rate of hydrolysis because TTIP is easily transformed into Ti(OH) 4 when it directly reacts with water [3]. The process of FeTiO 3 sol formation with sol-gel method can be seen in Fig.…”

“…The development of preparation methods and applications of nano-sized materials has many advantages namely having large surface contact areas and their efficient use because of their small size [3,4]. According to Khan et al [5] and Maulidiyah et al [6], the characteristics of nanoparticles depend on their size, distribution, morphology and phase.…”

Preparation of ilmenite (FeTiO3) composite for antimicrobial under UV-visible lights irradiation was carried out to appropriate as a new antimicrobial material. The preparation of FeTiO3 by using sol-gel method was conducted by the titanium tetra-isopropoxide (TTIP) as precursor titania and added Fe(NO3)3 as Fe source. Subsequently, the antimicrobial test (Escherichia coli, Staphylococcus aureus and Candida albicans) was carried out under photocatalysis system. The FeTiO3 was formed on 2θ of 20°, 24°, 36°, 48°, 53° and 62° having crystal size 53.75 nm. Scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX) was investigated that the particle sized was under 100 nm and Fe element peak was on 6.398 keV. The antimicrobial test showedthat the efficiency of 15 % FeTiO3 was active under visible light irradiation to inhibit of E. coli, S. aureus and C. albicans with diameter zone were 18.778, 19.889 and 20.22 mm, respectively.

The degradation of methylene blue dye has been conducted by Ag@S-TiO2/Ti electrode to increase the plasmon effect on visible light. The addition of silver metal was applied using electrodeposition method. While the S-TiO2 was prepared by sol-gel and immobilization on TiO2/Ti electrode. The results showed that the X-ray diffraction pattern of TiO2/Ti electrode was anatase crystal. Fourier transform infrared analysis in the wavenumber of 1120 and 413 cm -1 indicated the existence of S-O and Ti-O bonds. Supporting by scanning electron microscope and energy dispersive X-ray (SEM-EDX) on Ag@S-TiO2/Ti electrode, the existence of Ag, Ti and S were 2.9, 4.5 and 2.3 KeV, respectively. The plasmon effect identity was active on visible light irradiation confirmed by the photoelectrocatalyst system using linear sweep voltammetry (LSV). Based on the UV-visible spectrophotometer measurement the efficiency of methylene blue degradation was 81.15 % on 0.5 ppm.

In the present study, C,N-codoped TiO 2 (C,N-TiO 2 ) thin film photoanodes are prepared by a thermal treatment of titanium substrates embedded in various materials such as aluminosilicates (zeolite) or alumina particles and heat treated at 500 0 C for 3 h in a carbon contaminated muffle furnace. The prepared C,N-codoped TiO 2 photoanodes showed a significant water oxidation with the highest photo currents of about 100 mA cm À2 at zero bias versus (Ag/AgCl) using alumina as reactant medium under a standard 1 SUN illumination of solar simulator when compared to pure TiO 2 (~25mA cm À2 ) in 1 M KOH electrolyte. The C,N-codoped TiO 2 photoanode showed stable photocurrent for about 10 hours in the long term stability test. The physico-chemical properties of the prepared C,N-codoped TiO 2 thin film sample was examined by Scanning electron microscopy, Energy dispersive X-rays, X-ray diffractions, X-ray photoelectron spectroscopy, UV-visible diffuse reflectance spectroscopy and electrochemical impedance measurements for light harvesting (photo absorption) characteristics. It is found that the C,N-codoped TiO 2 exhibited strong absorption to visible-light region and improved electron donor density than pure TiO 2 from UV-Vis absorbance spectra and Mott-Schottky analysis, respectively. The enhanced photoelectrochemical performance of the C,N-codoped TiO 2 could be ascribed to the strong visible light absorption through band gap reduction and suppression of electrons-holes recombination process.
