Summary: A novel synergistic cocatalyst (N-CDs/m-TiO2) was successfully synthesized by compounding m-TiO2 with N-CDs, exhibiting significantly enhanced photocatalytic performance. The unique 3D interconnected porous structure not only increased the surface area, but also provided a high density of accessible active sites, facilitating the mass and charge transfer process. The enhanced light absorption ability and reduced energy band gap of N-CDs/m-TiO2, combined with the synergistic effect between N-CDs sensitization and the unique porous structure, contributed to its remarkably improved photocatalytic performance in wastewater purification.

Summary: In this study, a novel continuous flow-circulation photocatalytic reactor was developed for the treatment of synthetic wastewater containing a binary mixture of ammonia and phenol. N-Doped ZnO Beads (N-ZnB) were synthesized and used as catalysts, along with hydrogen peroxide (H2O2) and UV irradiation. The performance and characteristics of the N-ZnB catalyst were investigated through various analytical methods. The results showed that N-Doping of ZnO narrowed the band gap energy, leading to improved efficiency in the degradation of ammonia and phenol. Optimal degradation conditions were determined by examining operational parameters such as flow rate, pH, catalyst dosage, H2O2 concentration, and initial concentration of pollutants. Under the optimal conditions, N-ZnB catalyst achieved high degradation rates for both ammonia and phenol. The reusability and strength of N-ZnB were also evaluated, demonstrating its effectiveness as a catalyst for the degradation of ammonia and phenol in wastewater. Overall, this study is of great importance in the field of wastewater treatment.

Summary: A brand-new catalyst of C-modified and N-doped TiO2 (T3FN1) was synthesized via the hydro-thermal method using Tetrabutyl titanate (TBOT) and feathers of chicken as the precursor. The catalyst exhibited a unique three-dimensional folded rod-shaped micron structure, thanks to the abundant distribution of TiO2 nanoparticles (anatase phase) around the outer surface of the feathers template. Under visible light illumination for 30 minutes, the degradation rate of TCH reached 89.8% with T3FN1, which was 1.52 times and 2.62 times higher than that of TiO2 without template (T-3) and P25, respectively. Mechanism studies revealed that the chicken feathers served as natural organic templates to enhance the dispersity of TiO2 and nitrogen in feathers was directly doped into TiO2 to improve the catalysts' response to visible light. Furthermore, the carbon in the chicken feathers acted as a transmission medium for electric charges, promoting the spatial separation of photo-induced carriers. Moreover, T3FN1 showed wide adaptability and stability within a pH range, with the degradation rate of TCH still reaching 83.15% after 5 cycles. Overall, due to its unique structure and photocatalytic performance, the catalyst holds great potential for practical wastewater treatment.

Summary: A series of Ce, Bi, and N co-doped TiO2 photocatalysts were prepared to remove Chlorazol yellow (CY) dye molecules from water. The 5 wt% (Ce-Bi-N) co-doped TiO2 composite catalyst showed the best catalytic activity under sunlight irradiation. The catalyst achieved 97% degradation of CY molecules within 30 minutes and followed second-order kinetics. The developed catalyst can destruct CY molecules with a maximum rate of 23.1 mu g CY g(-1) min(-1) and the photodegradation kinetics depends on the concentration of CY.

Summary: Ni-based catalysts supported on sol-gel prepared Pr-doped CeO2 with varied porosity and nanostructure were tested for CO2 methanation reaction. The use of ethylene glycol in the synthesis led to a metal oxide support with larger pore size and volume, conducive to the deposition of medium-sized Ni nanoparticles confined into the nanoporous structure. The high Ni dispersion and availability of surface defects and basic sites greatly improved the catalyst's activity. CFD simulations and process simulation showed good validation with experimental results, confirming their ability in predicting CO2 methanation behavior.

Summary: In this study, Ni catalysts supported on Pr-doped CeO2 were investigated for CO2 methanation reaction. It was found that Pr doping introduced oxygen vacancies and promoted the dispersion of active metal. Low Pr loadings showed enhanced catalytic activity, while high Pr contents decreased the oxygen vacancy population and resulted in decreased catalytic activity.

Summary: This study investigated the effect of the SiO2/Al2O3 ratio in Zeolite Y as a support for heptane hydrocracking. The addition of W on Ni in the supported metal catalysts was also examined. The results showed that Ni-W bimetallic catalysts exhibited better catalytic activity due to enhanced metal dispersion and smaller particle size. Higher Si/Al ratio in Zeolite Y resulted in stronger acidity and balanced micro- and mesoporosity, which played a vital role in the catalytic performance.

Summary: The efficiency of direct and indirect ozonation in an advanced oxidation process (AOP) was evaluated for the removal of pharmaceutical residues in intentionally spiked deionized water. Both direct and indirect ozonation achieved removal rates ranging from 34% to 100% for the parent compounds. However, the study suggests that despite using accepted and affordable concentrations of ozone and radicals, the parent compounds were not fully degraded but transformed into 25 new intermediate products. These transformation products (TPs) were structurally similar to the parent compounds and exhibited similar persistence, stability, and toxicity. Some TPs were even more toxic than their parent compounds. Therefore, additional treatment is necessary to enhance the AOP for the degradation and removal of both parent compounds and their TPs to ensure safer release into the environment.

Summary: The atmospheric water generator (AWG) is a commercially available device that produces large volumes of water from the air in a short time. It can be used in most regions of the world to address chronic and acute drinking water scarcity. However, the impact of air chemical composition on the quality of AWG-produced water is not well understood. In a survey conducted in a heavily polluted industrial environment, AWG-produced water was found to meet drinking water standards for most contaminants, except for specific parameters such as nickel, dichloromethane, and ammonia.

Summary: This study explores the disinfection kinetics of SARS-CoV-2 variants by 267 nm UV-LED. The results show that all variants have an average reduction in copy number of more than 5 logs at 5 mJ/cm(2) dose, but there is inconsistency, especially for the Alpha variant. Increasing the dose to 7 mJ/cm(2) does not increase average inactivation, but significantly reduces the inactivation inconsistency, making it the recommended minimum dose. Sequence analysis suggests that the difference between the variants may be due to small differences in the frequency of specific UV extra-sensitive nucleotide sequence motifs. The use of UV-LED for the prevention of SARS-CoV-2 spread offers many advantages but careful consideration of UV dose is necessary.
