Summary: In this study, the uptake capacity of CO2 by a metal organic framework (MOF) was investigated using simultaneous thermal analysis (STA) coupled with Fourier transform infrared spectroscopy (FTIR). The results showed that the MOF had the highest adsorption capacity at 25 degrees C and 2.1 bar pressure. The regenerability and structural stability of the MOF were tested over multiple sorption cycles and confirmed by time-based absorbance on FTIR. The combined intrinsic properties of the MOF make it a promising CO2 adsorbent for industrial applications.

Summary: The burning of fossil fuels is causing an increase in the earth's average temperature by releasing large amounts of CO2 into the atmosphere. Effective strategies to reduce the concentration of CO2 are necessary. This study uses molecular simulations to investigate CO2 adsorption on zeolites and identifies Linde Type A zeolite as the best option for CO2 adsorption. The study also explores the structural features of zeolites and their impact on CO2 adsorption, as well as the use of cation doping to enhance CO2 adsorption.

Summary: This state-of-the-art review explores various adsorbents for CO2 adsorption in low and high-pressure applications, such as Metal-Organic Framework (MOF), Activated Carbons, Carbon Molecular Sieve (CMS) and zeolites. Activated carbons are identified as the most suitable candidate based on their equilibrium uptake, rate of adsorption, isosteric heat of adsorption and cost. The review compares different adsorption models, their merits and demerits, and their applicability in CO2 adsorption systems. It is found that high-grade activated carbons perform better in terms of equilibrium uptake and kinetics compared to MOFs, but MOFs have higher cost and slower kinetics.

Summary: The presence of nanoparticles in drinking water raises concerns about their potential risks to human health and the efficacy of water treatment plants in removing them. This study examines the efficiency of granular activated carbon (GAC) in removing CeO2 nanoparticles. The results show that GAC has a good affinity for nanoparticles, with higher adsorption capacity and removal efficiency in lake water compared to ultrapure water. The adsorption mechanism is mainly controlled by electrostatic attractions, and mass transfer processes play a role in the removal of nanoparticles in lake water.

Summary: In this study, a high alumina content (Si/Al=1.5) high order aluminosilica monolith (HOASM) composite was successfully fabricated using a reproducible and simple one-pot synthesis strategy. The geometry of the HOASM composite was controlled using microemulsion phases of copolymer P123 as soft templates. The pore structures of the composite were characterized, and the presence of aluminum species in the silica pore structure significantly influenced the acidity of the nanoadsorbent. The HOASM composite was used to remove Crystal violet (CV) dye from wastewater, and the multi-directional pores and mesostructural geometries of the adsorbent were found to improve the coverage of CV dye on the composite surfaces. The performance factors such as temperature, adsorbent dose, concentration, pH, and contact period were investigated, and it was determined that the optimal pH for CV dye adsorption on HOASM composite was 8. The adsorption isotherm followed the Langmuir model, and the kinetics followed a pseudo-second-order model. Thermodynamic experiments showed that the CV dye adsorption on the HOASM composite was endothermic and spontaneous.

Summary: Photocatalytic degradation is a promising method for reducing water contamination caused by increasing industrialization and population growth. Metal oxide photocatalysts, with their narrow band gap and low recombination rate of charge carriers, have shown effectiveness in this regard. In this study, BiOCl/PANI composites with different weight ratios were synthesized and characterized. The synthesized photocatalyst demonstrated excellent photocatalytic activity in degrading pollutants under natural sunlight irradiation. The results suggested that the 15% BiOCl/PANI hybrid showed the best performance, degrading 97% of Rh-B and 77% of TC with high rate constants.

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.
