Summary: The in situ synthesis of metal-organic framework crystals incorporated into natural polymers allows for the efficient manufacturing of large-sized adsorbents for practical adsorption processes. CuBTC/CS composite granules were successfully prepared by dispersing Cu2+ ions into the CS matrix, which subsequently grew into CuBTC crystals incorporated in the CS network. The quality of the composites was evaluated and the highest quality material was used as an adsorbent for toluene uptake, with the adsorptive interaction and kinetic behavior of the adsorption process analyzed.

Summary: Sodium alginate/carboxy-methyl cellulose/Cu-based metal-organic framework (SA/CMC/Cu-BDC) nano-composite beads were prepared and characterized. The composite beads exhibited high surface area and showed promising adsorption capacity for Tetracycline (TC) antibiotic. The adsorption process followed Langmuir isotherm model and pseudo-second-order kinetic model. Thermodynamical analysis suggested that the adsorption of TC onto the composite beads was spontaneous and endothermic. The interactions of hydrogen bonding, electrostatic, and 7C-7C played significant roles in the adsorption process.

Summary: In this study, a fully electrified temperature vacuum swing adsorption (TVSA) method was investigated for adsorbent regeneration in post-combustion carbon capture. Different strategies of simultaneous and sequential heating and evacuation were applied, and the performance indicators included the adsorbate loading, bed pressure, bed temperature, and mole fraction of CO2 at the outlet. By using the inductive TVSA process, it took significantly less time to reach a 90% regeneration level compared to using only vacuum evacuation. Additionally, short heating and evacuation times were found to maintain a large portion of the total bed capacity as working capacity.

Summary: A major challenge in Cyclic Swing Separation using flexible adsorbents is their very low-pressure hysteresis that hinders efficient desorption. Mg-Gallate MOF, a flexible adsorbent, shows very slow and inefficient desorption in pressure or temperature swing. Therefore, a novel strategy combining Magnetic Induction Heating with a vacuum swing is presented for fast and efficient CO2 desorption from flexible adsorbents at a moderately elevated temperature (70 degrees C).

Summary: This study reports a new type of periodic mesoporous organosilica (PMO) nanotubes, referred to as hollow ring PMO (HR-PMO), capable of promoting methane clathrate hydrate formation under mild working conditions and at high water loading. The HR-PMO nanotubes exhibit a steep single-stepped isotherm and a noticeably high methane storage capacity. Supported by ex situ cryo-electron tomography and x-ray diffraction, the findings suggest that HR-PMO nanotubes promote clathrate hydrate nucleation and growth by distributing and confining water in the mesopores of their outer wall, central channels, and external surface. These results highlight the potential application of organosilica materials for pressure-based storage of biomethane in confined clathrate hydrates.
