The combination of adsorption and photodegradation processes is an effective technique for the removal dye contaminants from water, which motivating development novel adsorbent-photocatalyst materials wastewater treatment. Herein, nanocomposite porous beads were developed using titanium dioxide (TiO2) nanotubes embedded in a sodium alginate (SA)/polyvinylpyrrolidone (PVP) matrix calcium chlorid...

Herein, two sunlight responsive photocatalysts including TiO2 nanoparticles (NPs) and TiO2/graphene quantum dots (GQDs) nanocomposite for degrading a textile dye, Reactive Black 5 (RB5), were prepared. The results showed that 100% of 50 ppm RB5 could be degraded by NPs TiO2/GQDs within 60 30 min irradiation, respectively. Hence, much better photocatalytic activity in degradation was achieved un...

this study investigated the photocatalytic behaviors for the nanocomposite of tio2 p25 and semnan natural zeolite in the decomposition of tetracycline under visible light in an aqueous solution. the structural features of the composite were investigated by a series of complementary techniques that included x-ray diffractometer (xrd), fourier transform infrared spectroscopy (ftir), scanning elec...

TiO2/ZrO2 nanocomposite was obtained by the sonochemical technique. In this method, two separate gels containing zirconium and titanium were prepared and mixed together. The precursor sol of zirconium was prepared from an aqueous solution of ZrCl4. The precursor titanium tetra isopropoxide (TTIP) dissolved in isopropanol. Mixing of Titanium and Zirconium gels was resulted in a yellow TiO2/ZrO2 ...

in this work, the strength of cold roll bond of the commercially pure titanium (cp ti) sheet and the effect of tio2 nanoparticles on bond strength was investigated. through the accumulative roll bonding process, which is considered among the important severe plastic deformation processes, the creation of suitable bonds plays a significance role in the ultimate strength of the bond. thus, resear...

Density functional theory calculations were performed to investigate the interactions of NH3 molecules with TiO2/MoS2 nanocomposites in order to completely exploit the adsorption properties of these nanocomposites. Given the need to further comprehend the behavior of the NH3 molecules oriented between the TiO2 nanoparticle and MoS2 monolayer, we have geometrically optimized the complex systems ...

We performed a density functional theory investigation on the structural and electronic properties of pristine and nitrogen-doped TiO2/Graphene oxide nanocomposites as the adsorbents for the removal of toxic NO molecules in the environment. We presented the most stable adsorption configurations and examined the interaction of NO molecule with these doped and undoped nanocomposites. It turns out...
