Summary: This study focused on designing earth-abundant and advanced bi-functional oxygen electrodes for efficient oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) by developing metal-semiconductor nanohybrids. The resulting catalyst showed enhanced performance in terms of half-wave potential for ORR, overpotential for OER, peak power density, specific capacity, and durability, outperforming commercial counterparts. The introduction of Ni into the Fe/Fe3C@NDC component manipulated the electronic structure of the catalyst and established an effective built-in electric field to promote interfacial charge-transfer, leading to significant utilization of electrocatalytic active sites and promising energy conversion.

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.
