Summary: In this study, modified intercalated kaolinite was anchored on the surface of LaFe0.5Co0.5O3 microspheres, resulting in improved photocatalytic activation and TCH removal efficiency under the Vis/PS system. Co doping was found to alter the charge distribution and accelerate charge separation, while photogenerated carriers were captured by O vacancies and Co/Fe active sites. SO4 center dot- was identified as the key radical species in the Vis/PS system. Overall, this study provides insights into the mechanism of MK/LFCO-catalyzed TCH degradation and highlights the potential of kaolinite-based catalysts for wastewater treatment under Vis/PS systems.

Summary: A ternary composite photocatalyst TiO2/Ti3C2Tx/AgI with high catalytic activity was successfully synthesized using simple solvothermal and coprecipitation methods. This composite catalyst exhibited superior photocatalytic degradation activity for tetracycline hydrochloride (TCH) under simulated sunlight. The enhancement of photocatalytic activity can be attributed to the high conductivity and efficient transfer of photogenerated carriers facilitated by Ti3C2Tx and the Z-scheme heterojunction formed with non-metal Ti3C2Tx as the solid medium. Superoxide radicals, singlet oxygen, and holes were identified as the main active substances in the photocatalytic degradation process.

Summary: Oxygen can generate reactive oxygen species in photocatalysis, promoting organic matter's mineralization. Therefore, enhanced oxygenation of the photocatalytic degradation system will help improve photocatalytic degradation efficiency. This study developed a novel high-gravity photocatalytic degradation method, which leverages the robust gas-liquid mass transfer capability of a supergravity rotating bed to realize the enhanced oxygenation of the photocatalytic degradation system. Specifically, this study used graphitic carbon nitride as the catalyst and tetracycline hydrochloride as the model pollutant. The effects of packing thickness, catalyst concentration, liquid flow rate, rotor speed, gas flow rate, and initial pH value on photocatalytic degradation performance were investigated. The results showed that the degradation rate of tetracycline hydrochloride reached 84.6 % under the optimal conditions of the rotating packed bed, which was 14.8 % higher than that of the traditional photocatalytic degradation process.

The construction of a BiOClO.5I0.5 and NH2-MIL-88B(Fe) heterojunction enhanced the photocatalytic-persulfate activity towards tetracycline hydrochloride (TCH). The combination facilitated the separation and transfer of photo-induced e- /h+ pairs, resulting in improved utilization of visible light. The BCI/NM-88B heterojunction exhibited better removal efficiency of TCH compared to BiOClO.5I0.5 and NH2-MIL-88B(Fe).

Summary: This study examined the oxidative degradation of tetracycline by ferrocene-modified graphite phase carbon nitride activated persulfate under light-assisted conditions. The results show that acidic neutral conditions are more conducive to tetracycline degradation, and the doping of ferrocene plays a key role in accelerating tetracycline removal by inhibiting electron-hole pair recombination. The synergy between photocatalysis and persulfate activation promotes the production of active species for tetracycline removal.

Summary: Utilizing organic structures to combine with TiO2 is an effective strategy for improving the photo-catalytic performance of TiO2. However, there is limited research on the impact of modulation at the organic molecular level for COF construction on the optical and electronic features of TiO2-COF heterostructures. In this study, a nitrogen-rich covalent organic framework (COF) was covalently integrated with amino-propyltriethoxysilane modified TiO2 (APTES-TiO2) through a Schiff-base reaction. The hybridized TiO2@TMP-COF with honeycomb-like morphology showed enhanced intramolecular charge transfer and photocatalytic CO2 reduction reaction (CO2RR) compared to the structure-similar COF established hybrid, TiO2@TM-COF. The study demonstrates the potential of creating heterostructures to improve light absorption and charge delivery in photocatalysis.

Summary: Compared to traditional single-axis motors, reluctance spherical motors (RSMs) can generate rotational torque in three spatial latitudes on a single motor, enabling three degrees-of-freedom (DOF) motion. This paper addresses the problem of consuming huge computational resources and long computation time in calculating the torque of RSM using the finite element method (FEM) by developing a torque model using the virtual work method. The results show that this method greatly reduces the amount of computing and simulation work with accurate modeling, providing a theoretical basis for the study of energization strategies and real-time control of RSM.

The nanocomposite showed significantly higher TCH degradation efficiency and CO2 photoreduction activity compared to pure ZnFe2O4 and SrTiO3. The enhanced activities were attributed to improved solar energy utilization and efficient electron-hole pair separation through a Z-scheme charge transfer model. The results suggest that ZnFe2O4-SrTiO3 nanocomposite has great potential for wastewater purification and CO2 reduction to renewable solar fuels.

The optimized 2mol%Fe-BOS achieved greatly enhanced TCH degradation efficiency up to 81.01% under visible light irradiation. The enhanced catalytic performance of Fe-BOS was mainly attributed to the migration of photoinduced electrons to Fe3+ to generate Fe2+ and the rapid production of hydroxyl radicals (center dot OH) via the reaction between Fe2+ and H2O2.

Summary: An efficient method for phosphate removal from wastewater is urgently needed due to the environmental issue caused by excessive phosphorus. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) were prepared and compared for their phosphate adsorption performance. L-Aspartic acid intercalated calcium aluminum layered double hydroxides (CaAl-Asp-LDHs) exhibited the highest phosphate adsorption capacity and faster removal rate compared to CaAl-LDHs. The phosphate adsorption mechanism on CaAl-Asp-LDHs involved electrostatic attraction, hydrogen bonds, complexation, and ion exchange. This environmentally friendly material shows promising potential for efficient phosphate removal from aquatic environments.

Summary: Studying the diffusion properties of hydrogen is important for designing new proton conductors. In the past, the chemical diffusion coefficient of hydrogen in proton conductors was usually obtained through a manual calculation method, resulting in difficulty in controlling the calculation accuracy. To address this issue, a mathematical algorithm and C language computer program were developed to calculate the chemical diffusion coefficient based on Fick's second law and Romberg numerical integral. The algorithm showed high precision and powerful computing function, and has the potential to replace the manual calculation method in calculating the chemical diffusion coefficient for hydrogen in proton conductors.
