Summary: This study investigates the effect of catalyst's surface Fe site and oxygen defect on the photo-Fenton reaction by using in-situ iron ions doped titanium dioxide meso-crystals as a model. The in-situ doping strategy anchors Fe ions on the surface of meso-crystals through oxygen vacancies, promoting the circulation of Fe3+/Fe2+ and enhancing the separation efficiency of photogenerated carriers. The interaction between oxygen vacancies and Fe ions improves the synergy between photocatalysis and Fenton reaction. The study demonstrates the efficient degradation of organic pollutants and mineralized intermediates under visible light irradiation, providing a potential path to prepare efficient visible light photo-Fenton catalysts.

Summary: Cu-doped TiO2 samples with different weight percentages of Cu loading (ranging from 1% to 4%) were synthesized using the sol-gel technique. The samples were characterized using powder XRD, SEM, and TEM. Cu-TiO2 with 1% and 2% Cu2+ doping exhibited a major anatase phase and a minor rutile phase, while samples with 3% and 4% Cu loading showed an increase in the rutile phase. UV-Vis absorption spectroscopy confirmed a decrease in the band gap of TiO2 with Cu doping. PL and XPS were used to investigate the optical properties, surface elemental composition, and oxidation state of the catalysts. Photocatalytic activity was evaluated for the removal of Rhodamine B and Cr (VI) under visible light. 3% Cu-doped TiO2 showed the highest degradation and mineralization, and the simultaneous removal of Rhodamine B and Cr (VI) was more efficient compared to individual removal.

Summary: The purpose of this study was to investigate the effect of photocatalytic degradation using nitrogen and tungsten co-doped titania (TiO2) nanoparticles, which are cost-effective and environmentally friendly. The synthesized nanoparticles were analyzed using various techniques, including spectroscopy, microscopy, and spectrometry. The co-doping of metal and non-metal enhanced the photocatalytic properties of the TiO2 nanoparticles, particularly in the visible region. This resulted in improved absorption of visible light and reduced recombination of electron-hole pairs, leading to accelerated photodegradation. The bandgap of the titania nanoparticles was reduced after efficient doping, enabling the photodegradation of malachite green under visible light illumination. The results of photocatalytic degradation were confirmed using spectroscopy and high-performance liquid chromatography coupled with mass spectrometry.

Summary: This study aims to fabricate self-doped Ti3+-TiO2 microspheres and dye sensitized self-doped Ti3+-TiO2 composites with high surface areas and visible-light absorption for highly enhanced photocatalytic tetracycline degradation under visible-light irradiation. The experimental results showed that the obtained Ti3+-TiO2 microspheres showed enhanced visible-light capture capacity and a larger surface area. Besides, the obtained Eosin Y/Ti3+-TiO2 composites showed efficient visible-light absorption and highly boosted photocatalytic performance towards tetracycline degradation. The highest rate constant for Eosin Y/Ti3+-TiO2-9% composite reached as high as 0.06657 min-1, approximately 8.09 times that of commercial TiO2, strongly demonstrating the significant roles of dye sensitization. Finally, a reasonable dye sensitization visible-light photocatalytic mechanism was suggested.

Summary: This study examined the use of NiSe2/Ag3PO4 nanocomposite catalysts for photocatalytic degradation of RhB and BPA pollutants. The 20% NiSe2/Ag3PO4 composite exhibited the highest photocatalytic efficiency for both pollutants. Various factors, including dye concentration, catalyst amount, pH, and reaction time, were investigated. The study found that the 20% NiSe2/Ag3PO4 catalyst effectively degraded 10 ppm RhB in 20 min and 20 ppm BPA in 30 min. SEM, PXRD, and energy-dispersive X-ray spectroscopy were used to analyze the physical properties of the samples. The combination of NiSe2 and Ag3PO4 played a crucial role in enhancing the stability of the photocatalysts. The photodegradation of both RhB and BPA followed pseudo-first-order kinetic models with specific rate constants. A Z-scheme reaction mechanism involving superoxide anion radicals and holes was proposed to explain the photodegradation process.

Summary: In this study, Ag/TiO2 materials with different interfacial structures were prepared and used for the photocatalytic conversion of biomass-derived 5-HMF to value-added HMFCA. It was found that low-temperature reduction could enhance the photoinduced charge separation efficiency and the localized surface plasmon resonance effects. The 2.5% Ag/TiO2-LTR showed the highest HMFCA selectivity of 96.7% under visible-light illumination. However, the photocatalytic efficiency decreased significantly when the reduction temperature increased due to the encapsulation of Ag NPs by a thicker TiOx overlay.

Summary: The continuous presence of organic pollutants in industrial wastewater poses a significant threat to human health, necessitating urgent and effective treatment. Photocatalytic degradation technology, specifically the use of TiO2 photocatalysts, provides a viable solution for the removal of organic pollutants. However, the limited absorption of visible light by TiO2 hinders its full utilization. To address this issue, the study developed an environmentally friendly synthesis of Ag-coated on micro-wrinkled TiO2-based catalysts, enabling extended absorption of visible light. The synthesized C/F-Ag-TiO2 composite exhibited a significantly lower band gap energy and achieved a remarkable degradation rate under visible light, making it a promising candidate for highly efficient environmental remediation.

Summary: This study investigates the AlN nucleation layer issue in GaN high frequency telecommunication and power switching systems fabricated after heteroepitaxy on Silicon or Silicon Carbide. It is shown that using 3C-SiC as an intermediate layer can significantly decrease RF propagation losses. Measurements and analyses demonstrate that dopant diffusion into the 3C-SiC pseudo-substrate is confined beneath the interface, and a slightly conductive zone is present beneath the AlN/3C-SiC interface, explaining the low propagation losses obtained for the devices. This work highlights the importance and efficiency of the 3C-SiC intermediate layer as a pseudo-substrate.
