The construction of TiO2 nanotube arrays with oxygen vacancies is widely used for the photoelectrocatalytic degradation organic pollutants, but crystal defects often reduce stability catalyst. This article mainly in preparation a supported porous catalyst by anodic oxidation Ti foil and loading Au nanoparticles assistance Cinnamomum camphora leaf extract. obtained Au/TiO2 array was applied to methyl orange. efficiency enhanced removal plant molecules calcination anaerobic conditions, reaction rate constant increased 66% when heat pretreated at 673 K. In addition, catalytic activity maintained high level after 5 cycles application. After characterization X-ray photoelectron spectroscopy, thermogravimetric analyses, Fourier transform infrared, electrochemical impedance photoluminescence, played important roles reduction gold ions, nucleation atoms, stabilization prevent collapse. method photoelectrocatalysts would be expected apply development catalysts toward pollutants.

Recent Strategies to Improve the Photocatalytic Efficiency of TiO2 for Enhanced Water Splitting to Produce Hydrogen

Catalysts, Год журнала: 2024, Номер 14(10), С. 674 - 674

Опубликована: Сен. 30, 2024

Hydrogen production is one of the best solutions to growing energy concerns, owing its clean and sustainable assets. The current review gives an overview various hydrogen technologies, highlighting solar water splitting as a promising approach for production. Moreover, it detailed mechanism water-splitting reaction describes significance titania-based catalysts splitting. It further highlights diversified strategies improve catalytic efficiency TiO2 enhanced These include doping TiO2, dye sensitization, addition co-catalysts. Doping reduces bandgap by generating new levels in encourages visible-light absorption. Sensitization with dyes tunes electronic states, which turn broadens light-absorption capacity titania. Constructing heterojunctions charge recombination while co-catalysts increase number active sites rate. Thus, every modification strategy has positive impact on stability photocatalytic improved Lastly, this provides comprehensive description future outlook developing efficient enhance rate, thereby fulfilling needs industrial sector.

Effect of TiO2 Morphology on the Properties and Photocatalytic Activity of g-C3N4/TiO2 Nanocomposites Under Visible-Light Illumination

Molecules, Год журнала: 2025, Номер 30(3), С. 460 - 460

Опубликована: Янв. 21, 2025

This study focused on the preparation and investigation of g-C3N4/TiO2 photocatalysts using different TiO2 morphologies (anatase nanoparticles (TPs), poorly crystalline nanotubes (aTTs), well-crystalline anatase nanorods (TRs)) self-synthesized g-C3N4 (CN). The synthesis composites was carried out a mortar mixing technique to weight ratio 1:1. In addition, were annealed in muffle furnace at 350 °C for 2 h air. successful formation composite with mesoporous structure confirmed results XRD, N2 physisorption, FTIR analyses, while microscopic analysis techniques preservation morphology all investigated. UV-Vis DR measurements showed that investigated exhibited visible-light absorption due presence CN. solid-state photoluminescence electrochemical impedance spectroscopy lower charge recombination compared pure For example, transfer resistance (RCT) CNTR/2 TR CN calcined air significantly reduced 0.4 MΩ, 0.9 MΩ 1.0 highest photocatalytic performance materials tested, achieving 30.3% degradation 25.4% mineralization bisphenol A (BPA) dissolved water under illumination. comparison, components achieved BPA rates (between 2.4 11.4%) levels 0.6 7.8%).
