Summary: In this study, we investigate the stability and reaction mechanisms of synthesized one-dimensional transition metal dithiolene wires for the oxygen reduction reaction and the oxygen evolution reaction in acid solution using density functional theory calculations. Our results show that CoDW exhibits high catalytic activity for bi-functional ORR/OER with low limiting overpotentials through four-electron reactions, and by applying uni-axial strain, the adsorption strength of reaction intermediates on transition metal reactive sites can be optimized. These findings provide valuable insights into the rational design of non-precious metal-based electrocatalysts and suggest a new strategy of tuning adsorptions via uni-axial strain to develop efficient bifunctional electrocatalysts for ORR/OER.

Summary: By utilizing density functional theory calculations, this research systematically studied the ORR/OER performances of nitrogen-coordinated transition metal carbon materials and found that asymmetric tri-coordinated catalysts, particularly NiN3-C, exhibit stronger catalytic intermediate adsorption capacity and lower overpotential, making them highly efficient bifunctional catalysts for oxygen catalysis. The enhanced effect is attributed to additional orbital interaction, as evidenced by changes in d-band center and integral crystal orbital Hamilton population. This study not only provides a potential bifunctional oxygen catalyst, but also enriches knowledge in coordination engineering for tailoring the activity of single-atom catalysts.

Summary: Using first-principles density functional theory calculations, a pH-dependent microkinetic model is developed to evaluate the performance of transition metal catalysts embedded in nitrogen-doped graphene for the oxygen evolution reaction. It is found that reaction pathways involving intermediates co-adsorbed on the metal site are preferred and lead to enhanced catalytic activity. These findings highlight the importance of investigating reaction pathways on graphene-based catalysts and other two-dimensional materials with metal active centers decorated by spectator intermediate species.

Summary: The study investigates the deactivation mechanisms of alpha-manganese dioxide electrocatalyst during charge-discharge cycling using density functional theory-based analysis, attributing the deactivation to phase transformation from alpha-MnO2 to beta-MnO2 and the formation of the limiting *OOH species during oxygen reduction reaction.

Summary: The preparation of single atom Fe-N-C catalysts leads to the formation of oxygen-containing moieties. The contribution of the oxygen-containing part on the oxygen reduction reaction (ORR) conducted with Fe-N-C is often overlooked, and the mechanism of the oxygen-doping structure remains unclear. However, through density functional theory (DFT) calculations, it is found that the adjacent C-O-C structure promotes charge separation and reduces the adsorption of oxygen-containing intermediates, resulting in greatly improved ORR kinetics. Experimental verification further confirms this principle, and the design of FeN4-700/900 catalysts incorporating O-rich biomass carbon substrates demonstrates enhanced ORR activity and excellent Zn-air battery performance. This study provides insights into modulating active sites and practical applications of Fe-N-C catalysts.

Summary: Electrochemical production of H2O2 is an eco-friendly and cost-effective method. Metal-doped carbon-based catalysts are commonly used for 2e-ORR due to their high selectivity. The role of metals and carbon defects in H2O2 production is still unclear. This study obtained a Co-N/O-C catalyst with a Faradaic efficiency greater than 90% in alkaline electrolyte by varying the Co loading in the pyrolysis precursor. Detailed studies revealed that carbon atoms in C-O-C groups at defect sites were the active sites for 2e-ORR in the Co-N/O-C catalysts. The direct contribution of cobalt single atom sites and metallic Co for the 2e-ORR performance was negligible, but Co played an important role in the pyrolytic synthesis of the catalyst.

Summary: Recyclable and biodegradable bioplastics made from biomass resources, specifically citrus peels, have been developed using a novel top-down strategy. The bioplastics show excellent mechanical properties, easy recycling, and rapid biodegradation due to the lamellae structure formed by cross-linked pectin and cellulose micro/nanofibers. The pectocellulosic bioplastics also exhibit water stability, water vapor barrier properties, and antioxidant activity, making them potential substitutes for petrochemical-derived plastics in active food packaging.

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.
