Abstract A powder of titanium oxide nanoparticles (TiO 2 NPs) was synthesized in this study by anodizing 0.7 M HClO 4 and then annealing N at 450 °C for 3 h to produce TiO NPs-N as a catalyst. These were encrusted with Au utilizing the photodeposition procedure tetrachloroauric acid (HAuCl ) isopropanol sacrificial donors. With surface area 121 m g −1 , NPs/TiO catalyst has high area, according...

Freely assembled palladium nanoparticles (Pd NPs) on titania (TiO2) nano photocatalysts were successfully synthesized through a photodeposition method using natural sunlight. This synthesized heterogeneous photocatalyst (Pd/TiO2) was characterized through field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), BET s...

Commercially available TiO2 of anatase structure produced in the Chemical Factory Police S.A. was modified by doping Ag from AgNO3 solution via photodeposition method. The obtained amount of deposited Ag on TiO2 was in the range of 0.11 to 0.98 mass %. Deposition of Ag on TiO2 resulted in the retarding of the recombination reaction and formation of the higher amount of OH radicals on the photoc...

Photoanodes fabricated by the electrophoretic deposition of a thermally prepared zinc tantalum oxynitride (ZnTaO₂N) catalyst onto indium tin oxide (ITO) substrates show photoactivation for the oxygen evolution reaction (OER) in alkaline solutions. The photoactivity of the OER is further boosted by the photodeposition of cobalt phosphate (CoPi) layers onto the surface of the ZnTaO₂N photoanodes....

The development of photocatalysts with wide spectral absorption and high charge separation efficiency has always been a pursued objective for photocatalytic solar energy conversion. Herein, we reported wide-range visible-light-active Bi 4 TaO 8 Cl (BTOC) single crystal nanoplate dominating {110} {001} facets enhancing the intrinsic efficiency. Insitu selective photodeposition metals metal oxide...

Using the photochemical deposition of chromium hydroxide layers driven by a continuous Ar laser wave in a potassium chromate solution, we explored the adhesion and patterning properties of the induced deposit on glass substrates versus the composition and the pH of the photoactive solution. The experiments were performed with two interfering beams imprinting an optical pattern on the substrate ...
