Special Issue Information

Dear Colleagues,

The past two decades have witnessed the explosive growth of crystalline porous materials, including metal–organic frameworks (MOFs) and covalent organic frameworks (COFs) with typically extended networks, or metal–organic cages (MOCs) and porous organic cages (POCs) with discrete structures. Crystalline porous materials, constructed by coordination and covalent bonds, have exhibited various applications because of their structural tunability and modular nature. Significant efforts have recently been made to exploit crystalline porous materials with exceptional properties, and further improvements and investigations are highly required for the development of this field.

We will launch a Special Issue “Multifunctional Crystalline Porous Materials: Design, Synthesis and Applications” that comprises a collection of original research and review articles on the synthesis, structure and applications of these materials, including recent developments on MOFs, COFs, and MOCs. In summary, this Special Issue will provide a comprehensive overview of recent advancements in the field of crystalline porous materials.

In this work, amino-modified ZIF-90 (NH2-ZIF-90) was prepared by using butylamine as a modifier, and its effectiveness in adsorbing Au(III) from environmental samples was investigated. The morphology and structure of NH2-ZIF-90 were analyzed via SEM, XRD, FT-IR, and XPS. Optimal adsorption occurred after 12 h of shaking in a pH = 5 aqueous solution with 2 mg mL−1 NH2-ZIF-90. The adsorption kinetics conformed to a pseudo-second-order model, and the equilibrium data fit the Freundlich isotherm model well. Finally, NH2-ZIF-90 was successfully used in lake water and tap water samples for Au(III) adsorption, with recovery rates ranging from 81.0% to 93.3%. This study presents a novel approach for addressing Au(III) adsorption challenges. Full article

The development of alternative adsorptive separation technologies is extremely significant for the separation of C2H2/CO2 and CO2/CH4 in the chemical industry. Emerging metal–organic frameworks (MOFs) have shown great potential as adsorbents for gas adsorption and separation. Herein, we synthesized two layered Zn-MOFs, UPC-96 and UPC-97, with 1,2,4,5-tetrakis(4-carboxyphenyl)-3,6-dimethylbenzene (TCPB-Me) as a ligand via the solvent regulation of the pH values. UPC-96 with a completely deprotonated ligand was obtained without the addition of acid, exhibiting two different channels with cross-sectional sizes of 11.6 × 7.1 and 8.3 × 5.2 Å2. In contrast, the addition of acid led to the partial deprotonation of the ligand and afforded UPC-97 two types of channels with cross-sectional sizes of 11.5 × 5.7 and 7.4 × 3.9 Å2. Reversible N2 adsorption isotherms at 77 K confirmed their permanent porosity, and the differentiated single-component C2H2, CO2, and CH4 adsorption isotherms indicated their potential in C2H2/CO2 and CO2/CH4 separation.

The capture of radioactive iodine (129I or 131I) is of significant importance for the production of nuclear power and the treatment of nuclear waste. In recent years, crystallized porous materials have been extensively investigated to achieve highly effective adsorption of radioactive iodine. Herein, by using the hydrothermal method, a Ni cluster-based framework (1) was successfully constructed through a self-assembly process. Driven by the π–π stacking interactions between π-electron-rich benzimidazole groups, [Ni5S6] clusters stack in a lattice, forming a porous framework with proper channels, rendering compound 1 as an ideal adsorbent for iodine. Compound 1 delivered a capability of iodine adsorption (2.08 g g−1 and 560 mg g−1 for gaseous and solution iodine, respectively) with stable cyclability. Full article

This study explores the electrochemical properties of additive-free NiCo₂O₄ derived from NiCo–metal–organic frameworks (MOFs) as a high-performance anode material for lithium-ion batteries (LIBs), excluding the effect of additives. NiCo-MOF was synthesized via an ultrasonic-assisted method and deposited on stainless steel foils using alternating current electrophoretic deposition (AC-EPD). The resulting thin films exhibited outstanding cycling stability and rate performance, maintaining a specific capacity of ~1200 mAh/g over 250 cycles at a high current density of 2.35 A/g, with nearly 100% Coulombic efficiency. Differential capacity analysis revealed enhanced redox activity at 0.8 V and 1.7 V during lithiation and delithiation, attributed to the decomposition of NiCo₂O₄ into metallic Ni and Co, followed by their oxidation to Ni2⁺ and Co3⁺, respectively. The gradual activation of electroactive sites, coupled with improved electrode kinetics and structural adjustments, contributed to the observed capacity increase over cycles. These findings underscore the potential of NiCo₂O₄ as a robust and efficient anode material for next-generation LIBs. Full article
