Summary: In this study, we designed novel ultrathin porous Bi2WO6 nanosheets with rich surface oxygen vacancies. The oxygen vacancies can narrow the bandgap, enhance light absorption, and promote electron separation and transfer. Additionally, the multiplication of oxygen vacancies increases the adsorption energy of O-2, activating O-2 to produce more center dot O-2(-). The porous structure enhances the adsorption capacity of the nanosheets to tetracycline molecules, allowing for a more efficient use of the center dot O-2(-). The nanosheets exhibit a degradation efficiency approximately 52.6 times higher than bulk Bi2WO6, showing great potential for removing organic pollutants.

Summary: The production of decarbonized ammonia through photocatalytic nitrogen fixation has the potential to revolutionize farm-scale fertilizer production. However, the cost of a complete photocatalytic system remains a critical factor. In this study, we found that the air separation unit accounts for a significant portion of the total system cost. Therefore, it is crucial to develop catalysts that can tolerate trace oxygen or operate under aerobic conditions to achieve cost parity with the traditional Haber-Bosch process. Among the various metal-doped titania photocatalysts, vanadium- and ruthenium-doped titania demonstrated consistent performance under aerobic conditions.

Summary: A new strategy based on surface photovoltage (SPV) of a layered semiconductor is reported for tuning the photoluminescence (PL) of Eu3+ ions. By changing the excitation light, the radiative rates, branch ratio, and crystal field splitting of the Eu3+ ions can be sensitively controlled. The results also show that the light-tunable SPV can change the polarization intensity around the Eu3+ ions and restrain the radiative transitions of the excited electrons.

Summary: This study reports the enhancement of upconversion (UC) luminescence efficiency in BiOBr:Yb3+,Er3+ (BYE) nanosheets by doping Li+ and Zn2+ and elucidates the enhancement mechanism. The doping improves the crystallinity of the samples, with codoping having a more pronounced effect. Under 980-nm laser excitation, the red emission of Li+-Zn2+-codoped BYE sample is significantly increased compared to Li+-doped BYE, Zn2+-doped BYE, and BYE samples. The luminescence enhancement is attributed to the reduction of crystal site symmetry and improvement of crystallinity upon Li+ and Zn2+ doping. Moreover, Li+ and Zn2+ doped BYE exhibits better photocatalytic performance than BYE, indicating the potential for achieving enhanced UC luminescence efficiency.

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.
