The photocatalytic oxidation of 4-methoxybenzyl alcohol to p-anisaldehyde (PAA) was performed in water with organic-free suspensions of home-prepared and commercial titanium dioxide (TiO2) catalysts. The nanostructured TiO2 samples were synthesised by boiling aqueous solutions of titanium tetrachloride (TiCl4), under mild conditions, for different times. The crystallinity increased with the boi...

Titanium and its alloys are widely used in modern supersonic aircraft rockets, submarines ships, the chemical food industries, as well other areas of technology. In process obtaining titanium from ore, workers may be exposed to metal dust (Ti) dioxide (TiO2), highly toxic compounds – gaseous tetrachloride (TiC14), hydrolysis products, chlorine phosgene vapors. The study influence produc-tion co...

Herein, hydrothermally synthesized hematite nanorods (NRs) co-doped with erbium and titanium, using titanium tetrachloride erbium(III) nitrate pentahydrate as the dopant sources, are presented. The effect of varied volumes erbium/titanium surface co-dopants on morphology, structural, optical, photoelectrochemical (PEC) properties NRs is investigated. pristine hematite, 40 μL -Er, -Er/20 -Ti-dop...

The synthesis of pharmaceutically and biologically active 2-amino-4H-chromenes was described using TiO2/nanoclinoptilolite (TiO2/NCP) as an efficient nanocatalyst under solvent-free condition. The TiO2/NCP was fabricated through modification of NCP with HDTMA, then the surface modified NCP was impregnated with titanium tetrachloride solution. Finally, the materi...
