Summary: Nanostructured BiOI-Q-Ag composites were prepared via a quercetin-assisted hydrolysis route, with varying Ag concentrations. Microscopic and spectroscopic investigations revealed efficient loading of Ag nanoparticles on 3D BiOI-Q nanoflowers, with higher density as Ag amount increased. The photocatalytic performance of the composites was enhanced compared to BiOI-Q, with BiOI-Q-Ag(2) demonstrating the best performance.

Summary: Flower-like BiOI decorated with CdS nanodots and iodine vacancies (VI) was used as a photocatalyst for the valorization of sodium lignosulfonate (SLS) under visible light. The introduction of iodine vacancies adjusted the band configuration, enhanced light absorption, and acted as electron traps. The intimate contact between BiOI and CdS nanodots facilitated charge transfer, significantly improving the photocatalytic performance. The CdS/BiOI-VI heterostructure exhibited the highest yield of vanillin, surpassing other photocatalysts and showing great potential for lignin valorization.

Summary: Accordion-like Ti3C2Tx MXene was successfully prepared via chemical etching, and TiO2 nanocrystals were grown on Ti3C2Tx nanosheets by in-situ oxidation using a powerful alkaline solution. The ratio of Ti3C2Tx and TiO2 was optimized, resulting in TiO2/Ti3C2Tx composites with excellent photocatalytic activity, especially for NO removal. The microstructure of TiO2/Ti3C2Tx composites contributed to the improvement of the separation and transfer efficiency of photogenerated carriers. The composite sample synthesized at 75 degrees Celsius showed the best NO removal efficiency, removing 70% of NO at a concentration of 600 ppb. This study offers a new approach for preparing high-performance MXene-based photocatalysts.

Summary: In this study, a well-defined 3D flowerlike mesoporous photocatalyst K-BiOI was successfully prepared by introducing oxygen vacancies (OVs) on the surface of BiOI, leading to improved hydrogen production rate under UV-Vis-light irradiation. The OVs on the K-BiOI surface played a key role in delaying photogenerated carrier recombination during the photoreaction process, resulting in enhanced catalytic performance for efficient H2 production.

Summary: The study explores the potential of bismuth oxyiodide (BiOI) as a material for photocatalysis, highlighting coherent phonons induced by femtosecond laser pulse excitation. It identifies the presence of an electric field in BiOI along the [001] axis and its role in efficient charge separation, crucial for photocatalytic applications. Additionally, the research reveals two major dephasing mechanisms causing the loss of vibronic coherence in BiOI.

Summary: A g-C3N4/BiOI/Bi2O2CO3 photocatalyst was successfully designed and prepared in this study, showing higher photocatalytic activities for the degradation of Rhodamine B under simulated sunlight compared to single components or dual-component catalysts. The results of electron spin resonance and active species trapping experiments indicated that h(+) and center dot O-2(-) were responsible for the photodegradation of RhB, suggesting a possible photogenerated carrier transport mechanism.

Summary: The widespread use of antibiotics has led to their continuous release and presence in the ecosystem, resulting in the emergence of antibiotic-resistant bacteria in aquatic environments. In this study, Ag/Ag2S@BiOI nanowires were synthesized and used as photocatalysts for the degradation of a model antibiotic, tetracycline. The nanowires showed efficient degradation performance under optimal conditions and exhibited negligible toxicity towards cells, indicating their potential as promising photocatalysts.

Summary: A novel BiOI/Bi2WO6 heterojunction photocatalyst responsive to visible light was synthesized, exhibiting high photocatalytic activity and stability. The main active substance was identified as holes, and the enhancement of photocatalytic activity was attributed to the separation of electrons and holes, inhibiting their recombination. This study provides a new approach for the visible light degradation of organic pollutants.

Summary: The study found that using NaOH as a base additive can improve the removal efficiency of NOx and SO2. The choice and ratio of oxidants can also affect the removal efficiency. In most cases, increasing the absorbed dose can increase the removal efficiency, but sometimes the choice and ratio of oxidants can also have an impact on efficiency.

Summary: Access to clean water is a major challenge in the 21st century due to the growing population. This study focuses on utilizing renewable energy sources to reduce water pollutants, particularly the harmful molecule Bisphenol A (BPA) found in plastics. By synthesizing two photocatalysts (BiOI and Bi2MoO6) using a microwave-assisted route, and creating BiOI/Bi2MoO6 heterostructures, the researchers found that the flower-like shape of BiOI/Bi2MoO6 exhibited high photocatalytic activity for BPA degradation. This was attributed to their matching electronic band structures and interfacial contact, enhancing the separation of photo-generated charges.

Summary: In this study, the compositional, morphological, and optical properties of particulate matter (PM) from the Monterrey Metropolitan Area in Mexico were investigated to identify their sources. Different analytical techniques were used to differentiate between particles derived from anthropogenic sources, such as metallurgical industry emissions and vehicle wear, and those from natural sources. The methodology was effective in speciating particles rich in different elements and accurately distinguishing between aluminosilicates and quartz based on their chemical composition rather than morphology.
