Summary: Developing durable photocatalysts for efficient antibiotics degradation is crucial for environmental purification. In this study, hierarchical organic-inorganic TCPP/Bi2MoO6 heterojunctions were successfully synthesized and showed superior photocatalytic performance in the visible light degradation of tetracycline hydrochloride. The high catalytic activity was attributed to the interfacial interaction between TCPP and Bi2MoO6, which facilitated charge carrier separation and enhanced visible-light absorbance.

Summary: In this work, diclofenac removal in tap water was achieved using TiO2 nanotube growth on Ti mesh substrate assisted by ozone generated from a hole-arrayed boron-doped diamond (HABDD) film electrode. The enhanced degradation effect from ozone molecules on TiO2 photocatalysis was attributed to the larger active surface area, increased charge separation rate, and contact area of ozone. This synergetic system shows promise in the treatment of pharmaceuticals in water.

Summary: Sulfated TiO2 is a promising photocatalyst for enhancing the photodegradation of organic pollutants. Different sulfate coordinated TiO2 catalysts were fabricated for the degradation of acetone. Treatment of Degussa TiO2 with concentrated H2SO4 showed significant improvement in acetone removal, while the parent TiO2 had low removal rate and rapid deactivation. The study revealed two forms of SO42- coordination on TiO2, with stable bidentate coordination acting as a trap center and loose monodentate coordination leading to deactivation.

Summary: In this study, a trace Fe3+ doped TiO2/Bi2WO6 composite photocatalyst was successfully synthesized and showed enhanced photocatalytic activity for toluene degradation. The optimal molar ratio of TiO2 to Bi2WO6 was found to be 1:2. The improved photocatalytic activity was attributed to the extension of carrier lifetime, increase of visible light absorption range, and formation of oxygen vacancies. Hydroxyl radicals and holes were confirmed to be the key reactive oxygen species (ROS) involved in the photodegradation reaction.

Summary: This study aimed to evaluate the adsorption influence of molecularly imprinted polymers (MIPs) on the oxidative degradation of 4-nonylphenol (4-NP) and its by-products in traditional wastewater treatment plants (WTPs). The results showed that MIPs can efficiently adsorb 4-NP, with maximum adsorption capacities of 201.1 mg/L and 500 mg/L, and the degradation percentages of 4-NP under ozone and UV conditions can reach 98-100%. The findings are significant for the identification and removal of emerging pollutants and their degradation by-products in environmental matrices.

Summary: This study investigates the promotion effect of microwave-absorbing photocatalysts on the photocatalytic oxidation process. The results show that the thermal effect of the microwave field enhances the separation efficiency of photogenerated electrons and holes, while the athermal effect improves the light absorption rate of the catalyst and promotes the generation of reactive oxygen radicals. These findings provide a theoretical foundation for practical applications.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
