Summary: Converting CO2 into carbon materials offers a solution to both environmental and energy issues, but low-carbon and energy-efficient conversion remains a challenge. In this study, a time-saving and energy-efficient strategy is reported for converting CO2 into carbon materials by reacting CO2 with Mg(AlH4)2 in a matter of seconds. The graphitization degree and pore structure of the synthesized carbon materials are found to be regulated by CO2 pressure, and the highly graphitized carbon exhibits high capacity and long cycle life for lithium storage applications.

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.
