Summary: The use and discharge of antibiotics have caused great harm, and electrochemical oxidation is an effective method to solve this problem. In this study, Ti/PbO2 and Ti/PbO2-La electrodes were prepared by electrodeposition, and the electrochemical degradation of ceftazidime was explored using these electrodes. The results showed that the La-doped electrode had more active sites and better electrochemical performance, achieving a ceftazidime removal rate of 96.12% after 2 hours of degradation. The influence of various factors on the degradation efficiency was systematically evaluated, and a degradation pathway was proposed based on the identification of intermediate products.

Summary: Metal oxide semiconductor sensors have poor selectivity due to their wide reactivity to different gases. This study proposes a qualitative method for analyzing selectivity by modulating the working temperature to achieve p-n response conversion. CuOx sensor synthesized from metal-organic frameworks is investigated for its gas sensing performance to ppb-level NO2 at different temperatures. The CuOx sensor exhibits tunable sensing behavior, switching from p-type to n-type, ensuring accurate identification of specific gases.

Summary: In this study, a regular micron rod-shaped trimetallic MOF material was synthesized and demonstrated to have high capacity and excellent cycle stability as an anode material for lithium-ion batteries. The tri-metal MOF exhibited enhanced rate performance compared to single and bimetal MOFs, thanks to the synergistic effect of multi-metal mixing sites. Meanwhile, the porous surface of the electrode after cycles improved the penetration of electrolyte and migration of lithium ions.

Summary: In this study, a unique 1D Pd@CeO2-BDC catalyst with rich oxygen vacancies and uniformly distributed PdO clusters and PdxCe1-xO2-s species on CeO2 surface was fabricated. The intense metal support interaction in the MOF skeleton resulted in the substitution of Ce4+ in CeO2 lattice by Pd atoms, thus significantly affecting the structure and electronic properties of the catalyst. The excellent reactivity of MOF-derived catalysts was attributed to lower energy barriers for methane activation on the reconstructed surfaces, as revealed by experimental and theoretical calculations. This research provides a new approach for the construction of lean methane combustion catalysts.

Summary: Antibiotics cannot be completely removed through traditional treatment methods, posing a threat to human health. This study developed a Co/Ce-MOF electrode and carbonized it to obtain a MOF-derived carbon composite electrode. The Co/Ce-C350Air electrode showed high degradation efficiency for ceftazidime and demonstrated good electrochemical stability. The synergistic effect between Co and Ce metals improved the catalytic performance and stability of the electrode. The results provide a safe and effective strategy for antibiotic degradation.

Summary: A Ni metal-organic framework/black phosphorene heterostructure is used to optimize the performance of oxygen evolution reaction (OER). The p-type black phosphorene host increases the Ni-O bond polarizability of NiMOF, allowing for enhanced LOM pathway and OER performance. Experimental and computational results demonstrate the activated LOM pathway with a more balanced step barrier in the NiMOF/BP OER catalyst.
