Summary: In this study, a NH2-MIL-125(Ti)/amorphous TiO2 composite photocatalyst was synthesized by integrating amorphous TiO2 microspheres with a Ti-based MOF (NH2-MIL-125(Ti)) during hydrothermal process. The NH2-MIL-125(Ti)/amorphous TiO2 photocatalyst exhibited more than five times higher catalytic activity than pristine NH2-MIL-125(Ti) for the selective oxidation of benzylamine. Optical and electrochemical characterizations revealed that visible light absorption in NH2-MIL-125(Ti)/amorphous TiO2 originated from NH2-MIL-125(Ti), while faster electron transfer to molecular oxygen was attributed to amorphous TiO2. This study highlights the importance of integrating MOFs with metal oxides in enhancing visible light photocatalysis.

Summary: This article describes a study on hydrogen generation from aqueous methanol over a TiO2 up-conversion (CeF3:Ho3+) nanosystem (CHT) under visible light irradiance. CeF3:Ho3+ nanoparticles (about 4 to 8 nm) were synthesized and incorporated into TiO2 using a simple polyol reduction method. The successful formation of a CeF3:Ho3+-incorporated TiO2 nanosystem was confirmed through various characterizations. The results showed that the CeF3:Ho3+-incorporated TiO2 nanosystem exhibited enhanced photocatalytic activity and could be used as an effective photocatalyst for sustainable hydrogen generation under visible light irradiance.

Summary: In this study, a non-noble metal-based heterogeneous photocatalyst for visible light-driven CO2 reduction was reported. The catalyst, composed of a supramolecular framework of iron porphyrin complexes with pyrene moieties, exhibited high activity (29100 μmol g-1 h-1 for CO production) and selectivity (99.9%), surpassing other relevant systems. Furthermore, the catalyst showed excellent performance in terms of apparent quantum yield for CO production (0.298% at 400 nm) and stability (up to 96 h). This research provides a facile strategy to develop highly active, selective, and stable photocatalysts for CO2 reduction without the need for noble metals.

Summary: This study presents a new strategy of band gap engineering in covalent organic framework (COF) photocatalysts by varying the push-pull electronic effect. Four different COFs with fine-tuned band gaps and band edge positions were synthesized, demonstrating high-efficiency photobiocatalytic systems for NADH photoregeneration and formic acid production under visible light. Morphology-guided enhanced surface area and dual keto-enol tautomerism-induced push-pull effect were identified as key features in fine-tuning the photocatalysts.

Summary: Elliptic spherical staggered flower-like g-C3N4/TiO2 fluffy porous heterojunctions were prepared by solvothermal method using tetrabutyl titanate as titanium source and acetic acid as acid solvent. SEM and TEM showed that the ellipsoidal TiO2 was crisscrossed on the flowered TiO2, loaded on fluffy porous g-C3N4. The material exhibited good photodegradation of organic pollutants under visible light, and g-C3N4/TiO2-2 (CNT-2) could remove 99.5% MO within 120 min. In addition, CNT-2 exhibited remarkable photodegradation performance for single and binary mixtures. The main reason for improved performance is that elliptic spherical staggered flowerlike TiO2 and porous g-C3N4 form a heterojunction, which is benefit to reduce the electron-hole recombination efficiency of TiO2 and improve the separation of electron-hole pairs. This result presents a simple strategy for photodegradation of organic pollutants.

Summary: The method of assessing porosity using SEM images is ineffective when the substrate and coating have different average atomic numbers, resulting in different contrast of backscattered electrons. Previous analyses relied on manual distinction of microstructure elements and selective thresholding, which is subjective and prone to errors. A new method was presented using both backscattered electron images and elemental maps for distinguishing epoxy resin from hydrated cement-based substrate, with the help of multivariate comparative analysis, making detection and analysis more accurate and reliable.

Summary: We investigated the challenging CrCl3 surface using photon energy dependent photoemission (PE). By studying the core and valence electrons of cleaved single crystals in either ultra-high vacuum (UHV) or air, we confirmed the atomic composition with respect to the expected bulk atomic structure. The presence of a stable, but only partially ordered Cl-O-Cr surface was revealed by a common spectroscopic denominator. Through analysis of multiplet components, we quantified the electron charge transfer and the reduced crystal field due to the established polarization field. The methodology used in this study can have a significant impact on determining the structure of ordered sub-oxide phases in mono or bi-layer Cr trihalides.

Summary: The study aimed to reduce facultative pathogenic bacteria and antibiotic resistance genes from secondary effluent. The efficiency of various processes in removing antibiotic resistance genes was evaluated. The study investigated the removal of selected antibiotic resistance genes, bacterial regrowth potential, and the removal of total genomic DNA content using TiO2-CuPd photocatalysts under visible light radiation. The highest removal efficiency for most targets was achieved with TiO2-CuPd/VIS. Photocatalytic ozonation with TiO2-CuPd showed significant removal of facultative pathogenic bacteria and antibiotic resistance genes. Photocatalytic ozonation has great potential for eliminating antibiotic resistance genes.

Summary: A visible light driven BiOCl@ZnIn2S4 composite was successfully synthesized by growing ZnIn2S4 nanosheets on wide-band-gap BiOCl microplates, and it was used for the first time for photocatalytic glycerol reforming and hydrogen evolution. The optimized composite with 4% BiOCl microplates showed the highest photocatalytic hydrogen evolution rate of 674 lmol g-1h-1 with only 0.0625 wt% platinum. This work not only demonstrates the application of ZnIn2S4 photocatalyst in glycerol reforming, but also proves the enhancement of ZnIn2S4 performance under visible light by wide-band-gap BiOCl photocatalyst.

Summary: Graphitic carbon nitride (g-C3N4) catalysts were synthesized using melamine, urea, and thiourea as precursors, and their influence on photocatalytic performance was investigated. Urea-based catalyst (UCN) showed the best results under all radiation sources, followed by thiourea and melamine. UCN achieved higher degradation of parabens under UVA compared to visible light, while natural sunlight had the highest removals using UCN. UVA lamps consumed 45% less energy and costs. Photocatalytic ozonation using UCN and MCN showed superior performance and complete removal under 12 minutes.

Summary: For quantum systems or materials, tuning electronic/magnetic properties using external parameters is a common approach for studying their behavior. However, in Muon Spin Rotation/Relaxation experiments, the use of a pressure cell as an external stimulus can result in a higher background signal. To tackle this issue, we have developed a simulation tool called pySRIM to calculate the stopping fractions of muons in both the sample and the pressure cell.
