Summary: In this study, high-performance surface-enhanced Raman scattering (SERS) substrates and photocatalysts were successfully synthesized using TiO2 nanorod arrays co-sensitized with black phosphorus nanosheets and Ag nanoparticles. The resulting BP/Ag/TNR substrate exhibited excellent SERS sensitivity for the detection of organic pollutants, as well as self-cleaning abilities through photocatalytic degradation. The improved performance was attributed to the formation of high-density hot spots, expansion of optical capture abilities, and enhancement of charge transfer properties.

Summary: In this study, multi-prismatic hollow cubic CeVO4 microstructures were fabricated using a one-step solvothermal method without organic agents. The wall thickness of the CeVO4 microstructures changed radially with the quadrangular prism. Excessive V precursor favored the formation of hollow micro-cubic CeVO4 with wall thickness changing from 200 to 700 nm. These CeVO4 microstructures exhibited superior photocatalytic activity for CO2 reduction under visible light, with a maximum CO generation rate several times higher than other samples. This study provides guidelines for fabricating multi-assembled structures of ternary compounds and expands the exploration of spatial structure in multivariate compounds.

Summary: The use of photocatalysts is a promising method for the removal of Cr (VI) and rhodamine dyes in wastewater treatment. This study synthesized a composite of carbon nitride (C3N4), zinc oxide (ZnO), and black phosphorus (BP) and investigated its photocatalytic ability for the degradation of rhodamine B (RhB) and detoxification of hexavalent chromium ion. The composite showed high efficiency in removing RhB and reducing hexavalent chromium, and the active species involved in the photocatalysis process were identified. The composite also exhibited impressive charge separation and low recombination, resulting in higher photocurrent density compared to the individual semiconductors. The band gap values and the double Z-scheme mechanism of the composite were determined through various experiments and analysis. The results highlight the potential of this composite as an efficient and environmentally friendly photocatalyst for wastewater treatment.

Summary: A CoO-CdS heterostructured photocatalyst CC-2-300 loaded with carbon derived from chitosan was synthesized. It exhibits a significantly enhanced photocatalytic hydrogen evolution rate of 10.60 mmol g(cat)(-1) h(-1) under visible light irradiation, which is 7.21 times higher than that of pure CdS under the same conditions. This improvement is attributed to the formation of a direct Z-scheme heterojunction between chitosan-derived carbon supported CoO nanorods and CdS nanoparticles, which enhances carrier migration efficiency and reduces charge recombination on CdS.

Summary: In this study, radial heteromesocrystals composed of anisotropic SnO2(head)-TiO2(tail) nanorods with heteroepitaxial junction were successfully synthesized by a hydrothermal reaction using SnO2 nanocrystals as seeds. These heteromesocrystals exhibit significantly higher photocatalytic activity for the aerobic partial oxidation of ethanol to acetaldehyde compared to radial TiO2 homomesocrystals. The enhanced photocatalytic activity can be attributed to efficient light harvesting by multiple light scattering, effective charge separation through one-directional electron transport, and the electrocatalytic activity of SnO2 for the two-electron oxygen reduction reaction.

Summary: Red phosphorus has been demonstrated for photocatalytic hydrogen evolution, but the P vacancy defects in red phosphorus have a significant influence on its photocatalytic performance. This study establishes the crucial relationships between the intrinsic P vacancy defects and the charge dynamics, and reveals the detrimental effect of deep charge trapping induced by P vacancies on the photocatalytic performance of red phosphorus. Oxygen doping in the P vacancy sites is demonstrated to be an effective strategy for eliminating the detrimental defect states and enhancing the photocatalytic performance of red phosphorus. This research provides a promising way to tune the physicochemical properties of red phosphorus and other elemental-based materials for various applications.

Summary: The present study synthesized CuBi2O4-based nanorods using a co-precipitation method and investigated their photocatalytic degradation of caffeic acid (CA). By controlling the amount of Cu metal ions, the bandgap of CuBi2O4 nanorods can be tuned. The degradation of CA can be explained based on species distribution. The Cu metal ions change the electronic properties and antibacterial ability, making the synthesized CuBi2O4-based nanorod cluster a promising material for CA photocatalytic degradation.

Summary: M/ZSM-5 (M = Mn, Co, Cu) samples were prepared by impregnation and their catalytic performance in NH3-SCR of NO was tested. Cu/ZSM-5 exhibited the highest activity, followed by Mn/ZSM-5, and Co/ZSM-5 was the least active. In-situ DRIFTS analysis revealed the nature and evolution of surface species. Coordinated NH3, NH4+, and amide (-NH2) species derived from NH3 adsorption were found to be relevant for NH3-SCR, while bridged nitrate species derived from NOx adsorption were identified as the main active species. Bridged nitrate was more abundant and thermally more stable on Cu/ZSM-5, consistent with its higher activity compared to Mn/ZSM-5 and Co/ZSM-5. Different mechanisms, including Eley-Rideal and Langmuir-Hinshelwood, were observed for Mn/ZSM-5 at different temperatures, while both pathways coexisted for Co/ZSM-5 and Cu/ZSM-5.

Summary: In this study, H3PW12O40-modified MnOx catalysts (Mn-HPW) were used for NOx elimination with co-fed NH3. The optimal Mn-HPW0.02 catalyst exhibited over 90% NOx conversion at 90-270 degrees C. The incorporation of HPW increased the amount of Lewis acid sites of the catalyst, facilitating the reaction between NH3 and NOx and enhancing the low-temperature catalytic activity. The addition of HPW also mitigated overoxidation and improved the selectivity in the high-temperature region.

Summary: We have discovered a new wave localization mechanism in a periodic wave system, which is different from Anderson localization and flat band lattices, and can produce a novel type of flat band. By designing a special periodic confinement potential, we have demonstrated complete electron localization in an open waveguide. This phenomenon, called flat band localization (FBL), is explained by the concept of self-localized orbitals, with each unit cell of the waveguide behaving like an artificial atom.

Summary: This study provides evidence that dinuclear vanadium-tungsten sites are the most active catalytic sites in conventional V2O5-WO3/TiO2 SCR catalysts, contrary to the prevailing view. These sites have stronger acidity and higher concentration of vanadium 3d electrons, leading to improved NH3 adsorption and O-2 activation in SCR. This finding settles a long-standing dispute and has important implications for understanding SCR mechanisms and designing better catalysts.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
