Summary: The study on gamma-LiAlO2-Ag cermets integrated in a packed-bed membrane reactor demonstrates their potential for selective separation of CO2 and O2 at high temperatures, and simultaneous syngas production through oxidative CO2 reforming. The obtained cermets show excellent wettability properties against molten carbonates, corrosion resistance, and superior thermal stability, contributing to their performance in gas separation and syngas production. Long-term permeation tests also confirm the membrane's excellent thermal and chemical stability under continuous reaction conditions.

Summary: The need to recycle CO2 as a building block and move away from nonrenewable resources is emphasized due to the increasing levels of greenhouse gas emissions. The production of valuable products, such as bulk chemicals and fuels, from CO2 conversion is crucial. This Account focuses on the viability of producing C-1 chemicals (formaldehyde, formic acid, and methanol) and C2+ chemicals (acetic acid, ethanol, methyl formate, and oxymethylene ether), evaluating the use of homogeneous and heterogeneous catalysts based on their performance, reaction pathway, and optimization. However, there is limited information on achieving sustainable production of these commodities, which is crucial for commercializing successful catalysts. To achieve a net-zero emission transition, the use of green CO2 and H-2 in CO2 hydrogenation reactions, driven by renewable energy, is imperative. Enabling technologies will further advance the development and scale of CO2 conversion processes.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

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.
