Summary: Metal organic frameworks (MOFs) are gaining increasing research interest in thermal energy storage and conversion. In this study, a green synthesis procedure was used to produce a promising MOF for high water sorption, MIL-100(Fe), and its transition metal-doped derivatives. The synthesized materials were tested for water sorption and their surface properties were analyzed. The results showed that the nickel-doped MIL-100(Fe) exhibited the highest cooling effect and total surface free energy among the studied MOFs. The correlation between surface properties and water adsorption isotherms can provide crucial information for developing efficient thermal energy storage and conversion systems.

Summary: The synergistic control of ozone and fine particulate matter is an important research topic in the field of environmental studies. This study focused on the degradation of ozone pollutants using MIL-100(Fe) and MIL-100(Mn) materials. The results showed that MIL-100(Fe) exhibited superior photocatalytic activity, while MIL-100(Mn) had better catalytic efficiency at normal temperatures. The optimal photocatalytic performance of MIL-100(Fe) was observed at 10% humidity, while MIL-100(Mn) showed consistent catalytic degradation efficiency at humidity levels ranging from 10% to 90%. The degradation mechanism was proposed based on in-situ DRIFTS and ESR analysis, which were correlated with oxygen vacancy and photogenerated electron efficiency. Temperature Programmed Desorption (TPD) analysis detected a large number of Lewis acid sites in MIL-100(Mn), which contributed to its excellent performance in normal temperature degradation under high humidity. This work expands the practical application of ozone removal and improves degradation efficiency.

Summary: In this study, MIL-100(Fe) metal-organic framework (MOF) was synthesized and used as an efficient adsorbent for removing Dacarbazine (DTIC) from contaminated water. The synthesized MOF particles exhibited high adsorption capacity due to their high surface area and suitable porous structure. The adsorption of DTIC onto the MOF followed the pseudosecond-order kinetic model and Freundlich isotherm model, and the adsorption mechanism was attributed to electrostatic interaction.

Summary: Lignin holds great potential as a renewable and abundant raw material for the production of valuable chemicals. Transition metal carbides and nitrides, due to their high hydrodeoxygenation activity, low ring hydrogenation activity, low cost, and good stability, are highly suitable for producing aromatics from lignin. However, a comprehensive summary and critical analysis have not been reported yet. In this minireview, recent advances in transition metal (Mo, W) carbide- and nitride-catalyzed hydrodeoxygenation of lignin or its model compounds are summarized to gain a deeper understanding of the interplay between the support, structure, and catalysis. The focus is on the changes in catalyst performance associated with different structures, such as crystal phases, supports, doping metals, etc. Constructive suggestions are also provided for selecting the most suitable catalyst system for the desired product and further improving hydrodeoxygenation performance.
