Summary: This article investigates the kinetic model for dry methane reforming using Ni/Si-MCM-41 catalysts, with the single-site reversible Langmuir-Hinshelwood model showing the best fit among six models tested. The higher temperatures and lower flow rates resulted in increased methane conversion and hydrogen production, with methane conversions over 85% and H2/CO ratio near 1. The activation energy for the best model was estimated to be 76.6 kJ/mol, demonstrating its potential for mathematical modeling in reactor simulation for syngas or hydrogen-rich gas production.

Summary: This study systematically investigates the C-H bond activation mechanism on Pt/MgO catalyst with O-2, O-H2O, and CO2. It is found that dry reforming of CH4 (DRM) exhibits weaker activity compared to reforming or partial oxidation of CH4. Pressure dependence shows that CO has negligible effect, suggesting the involvement of CO2 in CH4 activation as a whole molecule. The reaction between adsorbed CH4 and CO2 to form formate and methyl species is kinetically relevant. Experimental results confirm that both CO2 and CH4 derivatives are the most abundant surface intermediates.

Summary: Combining solar light and heat in dry reforming of methane (DRM) is a promising technology for CO2 reduction and increased solar energy utilization. The mechanism of the reaction and the synergistic effects of solar light and heat in DRM are investigated using a nanoscale Ni/CeO2 catalyst. The results show that the conversion rate of CH4 increases by 39.74% and the reaction temperature is reduced by 45 degrees C under photo-thermochemical conditions. Solar light enhances the dissociation of CH4 and the production of HCOO* on the catalyst surface, leading to improved DRM performance. These findings contribute to the understanding of the synergistic effects of solar light and heat and guide the conversion of CO2 into fuel using solar energy.

Summary: The effects of vanadium promotion on gamma-alumina supported nickel catalysts for methane dry reforming were investigated. The introduction of vanadium was crucial to hinder catalyst deactivation by coke deposition. The formation of nanotubes was reduced and hydrogen yield increased. When coupled with calcium, selectivity toward hydrogen/syngas production was improved. Under concentrated gases, vanadium was fundamental for a higher activity, with an increase of 30% and 15% in CH4 and CO2 conversions compared with the non-doped catalyst.

Summary: CO2 utilizations and conversions play a significant role in reducing greenhouse gas emissions and regenerating industrial exhausts. Metal oxides, as catalysts, have been proven effective in adsorbing and activating CO2 based on surface acidity/basicity and oxygen defects. This review comprehensively summarizes the impacts of these physicochemical properties of metal oxides on CO2 adsorption and activation, with a focus on CO2 conversion activity, product yield selectivity, and catalyst stability in reforming and hydrogenation reactions. Additionally, the review explores the structure-performance relationships, reaction/deactivation mechanisms, and origins of surface acidity/basicity and oxygen defects.

Summary: Imino hypercrosslinked polymers (NH-HCPs), amino hypercrosslinked polymers (NH2-HCPs), and carboxyl hypercrosslinked polymers (COOH-HCPs) were synthesized as highly efficient adsorbents for doxycycline hydrochloride (DOX) in water. The NH-HCPs exhibited the highest specific surface area and adsorption capacity, while the COOH-HCPs showed the strongest adsorption capability. Structural adjustments played a more significant role in improving adsorption performance compared to functional adjustments. The primary DOX adsorption mechanism involved hydrogen bonding and other mechanisms.

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.
