Summary: The contamination of water resources is a major environmental concern, especially the presence of hazardous pollutants such as phenol. Therefore, developing cost-effective techniques to remove phenol from water is crucial. This study investigated the use of silver-doped zinc oxide nanorods (Ag-ZnO NRs) for the degradation of phenol under sunlight. The synthesized Ag-ZnO NRs exhibited two distinct structures, hexagonal and cubic, and their optical properties showed significant improvement due to silver doping. The 0.5% Ag-doped ZnO NRs showed the highest photocatalytic activity, achieving a degradation rate of 98.5% for phenol removal under solar light irradiation after 5 hours.

Summary: Semiconductor-based photocatalysis is a promising method for air purification by removing nitrogen oxide (NO) pollutants. However, the efficiency of photocatalytic treatment is hampered by sluggish carrier separation, catalyst deactivation, and incomplete oxidation. In this study, various ZnO structures with deliberate surface defect constructions were fabricated to address these issues. The results showed that ZnO rich in oxygen vacancies exhibited significantly enhanced NO removal efficiency and fewer toxic byproducts compared to pristine and vacancy-poor ZnO. Furthermore, the surface defects promoted not only carrier separation but also molecular oxygen activation, resulting in the generation of strong oxidant superoxide radicals and improved efficiency. Density functional theory calculations confirmed the successful adsorption and activation of NO and molecular oxygen on the defective surface, further contributing to the enhanced NO conversions.

Summary: Effective removal of dilute nitrogen oxide (NO, ppb) without NO2 emission is still challenging in environmental pollution control. The construction of photocatalysts with diversified microstructures and atomic arrangements has been found to promote NO adsorption, activation, and complete removal without secondary pollution. In this study, the microstructure of ZnO photocatalysts was regulated by altering the reaction temperature and alkalinity, resulting in enhanced NO removal and reduced NO2 yields through defect-related surface-interface aspects. Mechanistic exploitations revealed that regulated microstructures, defect-related charge carrier separation, and strengthened surface interactions contributed to improved NO removal and simultaneous avoidance of NO2 formation. This investigation sheds light on the facile regulation of microstructures and the roles of surface chemistry in the oxidation of low concentration NO in the ppb level upon light illumination.

Summary: This study reports on the low-temperature carbon monoxide (CO) oxidation using a silver/silica aerogel (Ag/SiO2 AG) catalyst. The catalyst was prepared via a sol-gel synthesis followed by supercritical ethanol drying, resulting in a highly stable and sinterproof catalyst with easy reactant diffusion. The Ag/SiO2 AG catalyst exhibited enhanced catalytic activity due to the prevention of silver nanoparticles agglomeration and the facilitation of well-dispersed active sites, leading to improved mass heat transfer. The catalyst's pretreatment conditions played a crucial role in achieving high CO conversion efficiency at low light-off temperatures, and the active sites responsible for the enhanced catalytic behavior were identified as Ag0.

The engineered nanostructure exhibited a wrinkled structure with a porosity of 22-25% and an average pore size of 24 nm, promoting the adsorption of pollutants. The ZnO films showed high photocatalytic activity with a removal efficiency above 92% and degradation rate constants of 0.0049 min-1 and 0.0121 min-1 under UVA and visible light, respectively.

Summary: Capacitive deionization (CDI) is a promising technique for purifying water by eliminating ions. Recent experiments have shown a natural imbalance in anion/cation adsorption even for solutions containing only sodium and chloride, and suggested a connection with Faradaic leakages. This study presents a new circuit model that considers leakages, separately accounts for leakages on both electrodes, and incorporates different leakage resistances. The model allows analysis and quantification of the influence of leakage resistance and other material properties on adsorption imbalance. Based on these findings, a multi-electrode (ME) device design is proposed to tune or eliminate the adsorption imbalance by distributing voltage across the electrodes appropriately.

Summary: Electrochemical deionization devices, such as capacitive deionization (CDI), are essential for global freshwater requirements, particularly for desalination of brackish water. The current study extends an electrolytic capacitor (ELC) model to improve stability and efficiency of CDI systems. The newly implemented strategies and theoretical extensions allow for the first fully coupled and spatiotemporal three-dimensional (3D) CDI model. The study investigates a flow-through CDI device structure and finds that asymmetric designs may still perform reasonably well in normal operating conditions.

Summary: Intercalation host compounds (IHC) are potential candidates for selective ion removal from water. Recent theoretical developments suggest that electrochemical desalination using Nickel Hexacyanoferrate (NiHCF) electrodes could achieve a separation factor of 160 between K+ and Na+ ions, although the experiments have only shown a selectivity of around 3. This study investigates the reasons behind time-dependent selectivity suppression through theoretical derivation and a finite-element model. The findings reveal the importance of ion starvation and the surprising discovery that operating at low state-of-charge can increase selectivity to a theoretical value of 600, surpassing the previously assumed maximum. By implementing specific charging cycles, the time-dependent selectivity has been significantly improved from 3 to 450, and further enhancements can be achieved by combining IHC cathodes with membrane-less carbon anodes.

Summary: The oxidation of CO to CO2 via molecular rearrangements induced by catalytic metal atoms with oxygen intermediates is extensively studied in heterogeneous catalysis. This reaction is essential for reducing greenhouse gas emissions, particularly in low-temperature CO oxidation in vehicle catalytic converters. The catalytic activity of the palladium-supported silica aerogel (Pd/SiO2) catalyst was enhanced after the first cycle, attributed to the reconditioning of its pores. The presence of oxide forms of palladium in the SiO2 structure influenced the catalyst's performance by increasing the frequency of active sites. Additionally, the adsorption of CO2 onto Pd/SiO2 was evaluated, and the Langmuir model was employed to study the equilibrium adsorption behavior. Overall, the mesoporous Pd/SiO2 aerogel shows promise as a material for CO removal and CO2 capture at low temperatures.

Summary: This study proposes a sustainable method for hydrogen production using sunlight and cellulose as sacrificial agents during the photocatalytic water splitting process. The concentration of cellulose, pH of the system, and Pt loading were found to be important parameters affecting hydrogen production efficiency. The presence of specific molecular elements such as hemicellulose and xyloglucan significantly increased the hydrogen production rate. Carboxymethylation and TEMPO-oxidation of cellulosic biomass resulted in more stable suspensions with higher rates of hydrogen production. The results suggest that cellulosic biomass can be an attractive alternative for the photocatalytic splitting of water for hydrogen production.

This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.
