Summary: This study investigates the photocatalytic activity of magnetic CoFe2O4/g-C3N4/ZnO (CF-gCN/ZnO) nanocomposite as a visible-light photocatalyst. The heterojunction CF-gCN/ZnO photocatalyst achieved a photodegradation efficiency of 89% for degradation of methylene blue (MB) after 100 min of irradiation. The formation of heterojunction structures at the interface of g-C3N4 and ZnO leads to improved photocatalytic activity due to the separation of the photo-generated electron-hole pairs.

Summary: In recent years, industries have been releasing a large number of organic pollutants into the environment, causing pollution. Titanium dioxide (TiO2) is an important photocatalyst for removing organic contaminants. However, its application has been limited by the low utilization of visible light. To address this issue, black TiO2 was produced to enhance visible light absorption, and black TiO2/SnO2 composites were synthesized to improve photocatalytic activity. The composites showed superior degradation efficiency and stability under visible light, attributed to the formation of a type II heterojunction.

Summary: TiO2's limited photocatalysis efficiency and wide band gap have hindered its application in photocatalysis. However, Cs2AgBiBr6 double halide perovskite nanocrystals have been identified as a leading star in photocatalysis due to their strong visible light absorption and tunable band gap. By using a unique TiO2/Cs2AgBiBr6 composite, the photocatalytic process can be facilitated, leading to an improved photocatalytic rate of TiO2.

Summary: ZnO-CdS composites with different loadings of CdS were synthesized for NOx degradation under visible light. The presence of CdS influenced the morphology and structure of the composites, leading to the formation of needle/flower-like structures. The composites with CdS showed increased surface area and enhanced visible light absorption. Compared to pristine ZnO, the photocatalytic activity of ZnO-CdS composites was higher, with the optimal CdS loading being 15%. The formation of heterojunction structure between CdS and ZnO was responsible for the high photocatalytic performance of the composites.

Summary: The integration of semiconducting nanostructures with noble metal nanoparticles is increasingly favored for cost efficient energy and environmental applications. A facile aqueous synthesis method was reported to produce polymer-capped gold nanoparticles on free-standing 2D layered zinc oxide structures, resulting in ZnO/Au nanocomposites. The study found that the concentration of Au nanoparticles promoted the preferential growth of ZnO along the (002) wurtzite plane, with the resulting structures exhibiting improved absorptivity along the visible spectrum.

Summary: The glucose-tailored SnO2/TiO2/reduced graphene oxide ternary composite demonstrates superior photocatalytic activity due to its tailored microstructure and SnO2/TiO2 heterojunction, which enhance light absorption, charge transfer, and carrier separation. The composite can efficiently degrade organic pollutants by generating O·-2 and ·OH radicals through a redox reaction. Additionally, a possible photodegradation mechanism is proposed based on a Z-scheme transfer mode.

Summary: Photocatalysis has received significant attention in environmental remediation, with charge migration and solar light utilization being crucial for efficient performance. In this study, a ternary MoSe2/ZnO/p-BN (MZB) photocatalyst was successfully designed and synthesized. The optimal sample, with 30 wt% MZB, achieved a degradation rate of 99.2% for ofloxacin (OFL) under visible light irradiation, exhibiting catalytic reaction rates 5.33 times and 2.10 times higher than pure ZnO and ZnO/p-BN, respectively. The MoSe2/ZnO/p-BN system utilized p-BN to enrich pollutants and accelerate catalytic rates, while the hybridization of MoSe2 expanded the spectral response of the catalysts. The formation of stepped electron transport routes reduced the recombination rate of electron-hole pairs. Active species quenching experiments revealed that e(-), center dot O-2(-), h(+), and center dot OH played a major role in the removal of antibiotic contaminants. Analysis of OFL degradation intermediates provided insight into possible degradation pathways and proposed a reasonable photocatalyst mechanism. This work offers new ideas for the design of high-performance visible light responsive photocatalysts for pollution treatment.

Summary: A Co3O4 QDs-Ag2MoO4 (AMO) heterojunction was prepared by a hydrothermal method and characterized by various physicochemical methods. The SEM images showed that AMO particles and Co3O4 QDs-AMO had 3D-hexagon and nanosheet morphology, respectively. The Co3O4 QDs-AMO photocatalyst exhibited a higher photoactivity compared to pure AMO nanoparticles, attributed to its lower charge recombination rate.

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.
