Summary: Bi/Bi2WO6-x heterostructures were successfully prepared by a facile one-step hydrothermal method, with selective introduction of oxygen vacancy and metallic bismuth into Bi2WO6 nanostructures, leading to significantly improved photocatalytic activity for the photodegradation of bisphenol A and its analogues. Additionally, the concentration of singlet oxygen (O-1(2)) was found to be highly dependent on and modulated by the content of oxygen vacancy and metallic bismuth, with the obtained products displaying efficient photocatalytic performance and enhanced stability.

Summary: The proposed oxygen vacancy (OVs) and Zn ion doping synergy BiOBr (Zn-VBOB) photocatalyst can more efficiently degrade antibiotics, generating more types of radicals as degradation active species. The mechanism was systematically studied through radical capture experiment and DFT calculation, revealing that the shortened band-gap resulted in easier h(+)-e(-) separation which played a more significant role in generating reactive radicals.

Summary: A simple approach for degrading organic pollutants based on copper doped sodium bismuthate (CSB) was proposed, allowing for continuous generation of reactive oxygen species without the need for irradiation or other chemicals. The reaction proceeds through two mechanisms, direct oxidation involving singlet oxygen and catalytic oxidation primarily yielding superoxide radical, providing insights into the oxidative activity of CSB for water treatment.

Summary: This study synthesized iron carbide-loaded activated biochar with a high surface area, which exhibited higher removal rate and capacity for bisphenol A (BPA) compared to traditional zero valent iron-loaded biochar. The adsorption and degradation mechanisms were explored, showing that hydrogen bonds were formed between the COOH groups and BPA and that 1O2 was the major reactive species in the degradation process. Density functional reactivity theory also revealed the preference of ROS attacking degradation pathway 2 of BPA. Therefore, this iron carbide-loaded biochar can be a cost-effective and efficient alternative for contaminant removal.

Summary: TiO2-based visible-light-sensitive nanomaterials have been extensively studied for photocatalytic applications. This study investigated the influence of extrinsic oxygen vacancies on the photocatalytic performance of TiO2-based charge-transfer complexes (CTCs). The results showed that increasing the concentration of extrinsic oxygen vacancies did not improve the photocatalytic performance of TiO2 CTCs due to their role as recombination centers.

Summary: Photocatalysis technology has been studied extensively for environmental treatment, with research focusing on kinetics while overlooking the significant impact of oxygen interfacial mass transfer. Through simulations, it was demonstrated that oxygen concentration at the gas-liquid-solid triphase interface plays a crucial role in enhancing photocatalytic efficiency. Photocatalysts supported at this interface showed non-diffusion limited charge separation, leading to high photodegradation efficiency and potential for large-scale 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.
