Special Issue Information

Dear Colleagues,

Porous materials are important in established processes such as catalysis and molecular separations and in emerging technologies for energy and health. Porous organic materials refer to hydrocarbons that include pores (voids). Functional porous organic materials with intrinsic periodic (sub) nanometric pores include, but are not limited to, microporous zeolites, metal–organic frameworks, covalent organic frameworks, hyper-cross-linked polymers, conjugated microporous polymers, porous aromatic frameworks, porous organic cages, and covalent triazine frameworks, which have found wide applications (such as in adsorption and separation, filtration, catalysis, energy storage and conversion, mass transportation, drug delivery, etc.) because of their excellent adsorption, separation, ion-exchange, and catalytic properties.

This Special Issue aims to encompass the recent significant breakthroughs and the innovativel functions and practices in the field of porous organic materials to find useful applications and imparts a comprehensive understanding of the strategic evolution of the design and synthetic approaches of porous organic materials with tunable characteristics. We expect that these joint endeavors will provide insightful guidelines for the advancement of functional porous organic materials.

Abstract

Metal–organic frameworks (MOFs)-derived metallic oxide compounds exhibit a tunable structure and intriguing activity and have received intensive investigation in recent years. Herein, this work reports metal–organic frameworks (MOFs)-derived cobalt oxide/carbon nanotubes (MWCNTx@Co₃O₄) composites by calcining the MWCNTx@ZIF-67 precursor in one step. The morphology and structure of the composite were investigated by scanning electron microscope (SEM) and transmission electron microscope (TEM) characterization. The compositions and valence states of the compounds were characterized by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). Benefiting from the structurally stable MOFs-derived porous cobalt oxide frameworks and the homogeneous conductive carbon nanotubes, the synthesized MWCNTx@Co₃O₄ composites display a maximum specific capacitance of 206.89 F·g⁻¹ at 1.0 A·g⁻¹. In addition, the specific capacitance of the MWCNT₃@Co₃O₄//activated carbon (AC) asymmetric capacitor reaches 50 F·g⁻¹, and has an excellent electrochemical performance. These results suggest that the MWCNTx@Co₃O₄ composites can be a potential candidate for electrochemical energy storage devices. Full article

Abstract

The prevalence of facial nerve injury is substantial, and the restoration of its structure and function remains a significant challenge. Autologous nerve transplantation is a common treatment for severed facial nerve injury; however, it has great limitations. Therefore, there is an urgent need for clinical repair methods that can rival it. Tissue engineering nerve conduits are usually composed of scaffolds, cells and neurofactors. Tissue engineering is regarded as a promising method for facial nerve regeneration. Among different factors, the porous nerve conduit made of organic materials, which has high porosity and biocompatibility, plays an indispensable role. This review introduces facial nerve injury and the existing treatment methods and discusses the necessity of the application of porous nerve conduit. We focus on the application of porous organic polymer materials from production technology and material classification and summarize the necessity and research progress of these in repairing severed facial nerve injury, which is relatively rare in the existing articles. This review provides a theoretical basis for further research into and clinical interventions on facial nerve injury and has certain guiding significance for the development of new materials.
