Summary: In this study, Camellia oleifera shell-derived biochar (COSB) was prepared by one-step pyrolysis. The catalytic efficiency of COSB was found to be tunable by the pyrolysis temperature, with COSB-1000 prepared at 1000 degrees C showing the optimal activity in peroxymonosulfate (PMS) activation. The COSB-1000/PMS system exhibited good anti-interference ability and wide pH applicability, and the degradation of tetracycline hydrochloride (TC) was mainly dominated by the non-radical oxidation process, with the generated O-1(2) playing a vital role.

Summary: This study designed and synthesized a novel composite photocatalyst of Bi2O3/CdMoO4 using a deposition-oxidation method. It investigated the morphology, specific surface area, structure, optical properties, and photoelectric chemical properties of the Bi2O3/CdMoO4 composite. The results showed that the dispersion of Bi2O3 nanoparticles on the surface of CdMoO4 polymers increased light absorption and facilitated the photocatalytic reaction. The presence of a tight contact between CdMoO4 and Bi2O3 resulted in the formation of a heterojunction structure, promoting the separation efficiency of electron-hole pairs through an S-scheme mechanism.

Summary: This study presents a facile and cost-effective method to synthesize a stable photocatalyst (BiOBr/MMT) for sulfite activation under sunlight. The BiOBr/MMT catalyst demonstrates enhanced catalytic performance in degrading atrazine and various organic pollutants. The addition of MMT reduces the bandgap and increases the surface area of pristine BiOBr, leading to improved adsorption capability. The BiOBr/MMT-sulfite system generates oxysulfur radicals, h(+), and O-1(2) as the dominant active species. The proposed degradation mechanism highlights the vital role of sulfite adsorption on the surface of the photocatalyst.

Summary: The presence of antibiotics in water bodies seriously endangers the ecosystem and human health. Advanced oxidation processes (AOPs) based on peroxymonosulfate (PMS) are an effective method for removing antibiotics, but have a bottleneck problem due to hindered electron transfer. In this study, CuO with rich oxygen vacancies (OVs), MSCuO-300, was synthesized to efficiently degrade tetracycline hydrochloride (TTCH) (k = 0.095 min -1). The presence of OVs played a dominant role in the activation and catalytic pathway, leading to increased PMS activation rate and production of active species. MSCuO-300/PMS also showed excellent adaptability to real water parameters. This study provides a successful case for purifying antibiotic-containing wastewater using efficient catalysts designed through oxygen defect strategies.

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.
