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.

Zeolite Socony Mobil-5 (ZSM-5) was successfully synthesized by a hydrothermal method from the silicon dioxide (SiO2) precursor prepared fro m rice husk ash. Titanium dioxide (TiO2) nanoparticles were decorated on ZSM-5 substrate by a sol-gel method. ZSM-5/TiO2 materials were characterized by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), transmission electron microscope (TEM), and Brunauer-Emmett-Teller (BET) surface area analysis.

The present study investigated the photodegradation of 2,4- Dichlorophenoxyacetic acid (2,4-D) in a water environment using synthesized titania nanoparticles (TiO2-NPs). The TiO2-NPs fabricated by sol-gel method were distinguished by X-ray diffraction (XRD) and Transmission electron microscopy (TEM), Infrared spectroscopy (IR), and zeta potential measurements.

In this work, gold nanorods (AuNRs) with well-controlled aspect ratios were prepared using a modified seedgrowth method and covered by TiO2 layers through the hydrothermal reaction to improve stability. Integrating TiO2 with plasmonic rod-like gold nanoparticles could enhance their photo activity by the local surface plasmon resonance (LSPR) effect. AuNRs aspect ratios were controlled by varying the amount of seed solution, reducing agents, surfactant (CTAB), and titanium (IV) but oxide.

The concentration of the HCl reaction medium and the following aging are the essential factors affecting the formation and phase composition of the resulting TiO2 nanocrystals. TiO2 nanoparticles in the form of pure anatase and the rutile phase can be extracted and segregated from the suspension and precipitate of the synthesizing medium.
