Summary: Photocatalytic degradation can be enhanced by improving photo-generated electrons and expanding the absorption range of light through conductive polymers. In this study, Polyaniline (PANI) was synthesized with CdS, CdS-ZnS, and CdS-TiO2 nanocomposites and evaluated for the degradation of Acid blue-29 dye. The performance of composite photocatalysts was enhanced by PANI, and the properties of the nanocomposites, including charge transfer, molar ratio, surface morphology, particle size, thermal stability, and optical properties, were characterized. The photocatalytic activity and degradation rate were found to increase with the number of nanocomposites in the membranes. CdS-ZnS-PANI and CdS-TiO2-PANI nanocomposites showed higher photocatalytic activity compared to CdS-PANI due to the improved electron kinetics and reduced charge recombination. The efficiency of the photocatalysts remained stable after repeated use, indicating their potential use for water purification. The compatibility between CdS and Zinc and TiO2, along with improved charge carrier separation, contributed to the higher photocatalytic activity of CZP and CTP photocatalytic membranes compared to CdS-PANI. The study also demonstrated the commercial utility of the nanocomposites, as they were active in the near-ultraviolet to deep infrared range and exhibited enhanced stability and reusability. Therefore, the development of high-performance photocatalysts using conductive polymers and nanocomposites holds great potential for environmental purification and solar power conversion.

Summary: The geometric parameters have significant impacts on the properties of photoactivity materials. In this study, the geometric effects on photoluminescence and photodegradation of yolk shell structure were investigated by adjusting the cavity and shell thickness. The results showed that the charge interaction between the core and shell is the main factor for thin shell and cavity samples, while light scattering and accommodation space of intermediates provided by the cavity play a major role in samples with large cavity volume and thick shell. The study also discussed the TC degradation mechanism, possible degradation pathway, major reactive oxidation radical, and toxicity of products in detail.

Summary: Due to polluted water remediation, semiconductor nano photocatalysis has been considered as a promising approach to address the issue. However, the slow reaction rates and high electron-hole recombination have hindered their large-scale applications. In this study, heterogeneous nano photocatalysts, such as sol-gel-based mesoporous titania nanoparticles (TNPs) and silica-titania nanocomposite (STNC) supported with CdTe (CdTe/STNC), were synthesized for photocatalytic applications. The CdTe/STNC catalyst exhibited a large surface area and pore size distribution, and demonstrated high photocatalytic activity with methylene blue degradation of 95% after 180 min of ultraviolet radiation.

Summary: The presence of antibiotic residues, such as oxytetracycline (OTC), in wastewater effluents has created the need for monitoring trace concentrations to combat bacterial resistance. Surface Enhanced Raman Spectroscopy (SERS) is a promising technique for detecting and identifying low concentrations (ng/L) without sample preparation. A fibrillar support, Titania-Silica doped with silver particles, was developed in the SERS technique for detecting OTC. The doped ceramic fibers showed the presence of silver nanoparticles ranging from 30 nm to dendritic structures larger than 1 μm, depending on the synthesis conditions. The support doped with Ag at 19 V for 30 s exhibited the highest amplification factor (AF) of 44 for the OTC band at 1278 cm-1.

Summary: The construction of a heterojunction composed of zero-dimension nickel sulfide nanoparticles and cadmium sulfide flowers has led to significant improvement in photocatalytic H-2 production under visible light irradiation. The obtained nano composite with 25% NiS exhibits remarkable performance with an H-2-production rate 69.6 times higher than that of pristine CdS. The enhanced photocatalytic activity is mainly attributed to the intimate contact and efficient separation of photoinduced carriers across the interface.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
