Summary: This study investigated the adsorption isotherms and kinetics of methane in MIL-101(Cr) under different temperatures and pressures, finding that the delivery amount of methane can be enhanced by changing the charging and discharging temperatures. Additionally, it revealed that the adsorption rate of methane in MIL-101(Cr) is controlled by the diffusion process.

Summary: A new wash-coating technique was developed to coat a porous layer of MIL-101 (Cr) adsorbent on fused silica microchannels. The optimized adsorbent slurry was prepared using ethanol solvent, silica binder, and MIL-101 (Cr) and inserted into the microchannels. The coatings were characterized using SEM and water adsorption isotherms.

Summary: The study investigated the equilibrium and kinetics of CO2 adsorption by coconut-shell activated carbon impregnated with sodium hydroxide at 273 K. The CO2 adsorption increased with NaOH loading and exhibited three distinctive regions. The results showed an empirical correlation between effective pore diffusivity, CO2 adsorption, and NaOH loading.

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: Water adsorption in MIL-101(Cr) was studied through molecular simulations, revealing different pore-filling processes in the large, medium, and small cavities at varying pressures. The confinement effect on the structural properties of water and the role of stability of water clusters in the pore-filling processes were investigated. The formation of multimolecular water chains and clusters before condensation on inner surfaces of the cavities was observed.

Summary: This study prepared Hawthorn kernel activated carbon (HKAC) using a two-step method involving carbonization and thermal activation with potassium hydroxide. The HKAC exhibited good morphological integrity and crystalline state, and had a high specific surface area and pore volume. The optimal adsorption conditions were determined to be a carbonization temperature of 550 degrees C, HKAC concentration of 0.6 g/L, solution temperature of 60 degrees C, and pH of 6.0. The experimental results showed that HKAC was a cost-effective and green adsorbent for removing water and plants contaminated with fungicides.

Summary: The current research focuses on characterizing and comparing the physiochemical properties of seven commercially available activated carbons (ACs) as adsorbents for CO2 capture. The study found that the selected ACs have high micro and ultra-micro porosity, making them suitable for post-combustion CO2 capture. The study also estimated important thermodynamic properties of adsorption and confirmed that the selected ACs are suitable for various gas sorption applications.

Summary: A composite nano porous material of MIL-101(Cr)@AC was prepared through fluorine-free hydrothermal reaction to enhance methane uptake and storage density. Methane adsorption isotherms for both dry and wet samples were measured, and it was found that methane adsorption increased by 65.58% with the composite material due to the increase in specific surface area and pore volume. The contribution of hydrate to methane uptake is up to 40% and large methane storage density is anticipated, with methane volumetric uptake increasing by 38.03% under a mild condition (9.3 MPa and 274.15 K).
