Enhanced photocatalytic conversion of CO₂ over Ag-deposited TiO₂ nanotube arrays

Journal of Physics Conference Series, Journal Year: 2025, Volume and Issue: 3003(1), P. 012014 - 012014

Published: April 1, 2025

Abstract The photocatalytic (PC) performance of the Ag-tailored TiO 2 nanotube arrays (TNTAs) for conversion CO was evaluated in this study. A facile electrochemical deposition method employed to construct Ag-TNTAs binary nanocomposites. size and amount Ag nanoparticles (NPs) over TNTAs surface has been adjusted by limiting time anodization voltage. properties photocatalyst were determined using XRD, FESEM, UV-Vis DRS. as-fabricated photocatalysts showed improved light response compared pristine TNTAs. Among Ag-modified TNTAs, Ag/TNTAs-2 exhibited best PC rate under exposure visible light. Increasing NPs causes formation larger particles decreases electron-hole separation efficiency. boosted activity can be ascribed synergistic effect plasmon resonance (SPR) NPs, which subsequently prevented recombination photoexcited charge carriers.

Photo-fixation of Ag onto TiO2 Powder Films for Improved Photocatalytic Activity and Atomic-absorption Determination of Residual Noble Metal in Dyes Solution

Proceedings of the Bulgarian Academy of Sciences, Journal Year: 2024, Volume and Issue: 77(1), P. 20 - 29

Published: Jan. 29, 2024

For the first time, we photo-fixed silver ions (10–2, 10–3, and 10–4 M) onto films prepared from commercial TiO2 powder via ultraviolet illumination. The synthesis process is straightforward environmentally friendly. nanostructures are characterized by SEM, XRD, FAAS, UV/Vis spectroscopy for photocatalytic properties. X-ray diffraction pattern demonstrated phase of anatase structure. Flame Atomic Absorption Spectrometry used as a simple way to determine Ag+ content in solutions heterogeneous photocatalysis under UV research shows that at end degradation process, no observed both dyes – malachite green methylene blue. formation stable intermediates reaction OH with triarylmethane dye during resulted faster than In comparison pure TiO2, TiO2/Ag have higher efficiency. reason presence silver, which leads decrease recombination pairs charges.
