Summary: The performance of Al-air batteries, particularly in cold environments, has remained stagnant due to sluggish air cathode reactions. To address this issue, aqueous Al-air batteries were explored with an efficient catalyst for application under low temperature. Cu1Cop-N-C, synthesized by carbonization of Cu, Co co-doped ZIF-8 combined with MWCNTs, exhibited high oxygen reduction activities due to the synergistic effect in Cu1-Cop active sites and its unique 1D-3D porous nanostructure. Al-air batteries with Cu1Cop-N-C demonstrated remarkable performance in a wide service temperature range (-40-50 degrees C), providing a high start voltage of 0.7 V and a peak power density of about 16.58 mW cm-2 at -40 degrees C. It is anticipated that these metal single atoms with neighbored heterogeneous metallic particles could have broader applications in diverse energy conversion and storage fields.

Summary: In this study, CuO/Co3O4@CNTs catalysts were successfully prepared for bifunctional oxygen electrocatalysts using a facile and scalable coprecipitation strategy. This unique strategy allowed the uniform growth of CuO/Co3O4 nanoparticles on CNTs and the simultaneous pyrolysis process resulted in the generation of ultrafine CuO/Co3O4 heterostructures. Due to an abundance of heterostructures, oxygen vacancies and unsaturated chemical bonds were generated in CuO/Co3O4.

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.
