Special Issue Information

Dear Colleagues,

The research field of nanoporous materials is an interesting and exciting topic with countless researchers involved worldwide. Two types of hybrid solids have been developed during the last decade and are considered important subjects in this field. The first class includes porous organic frameworks (POFs), a general term for covalent–organic frameworks (COFs), covalent triazine frameworks (CTFs), porous aromatic frameworks (PAFs), hydrogen-bonded organic frameworks (HOFs), etc. POFs are made from organic building monomers with strong covalent bonds and have attracted a great amount of interest among researchers. The second class covers a range of solids, both oxides and non-oxides, crystalline and amorphous (zeolites, silica, metal–organic frameworks (MOFs), etc.). The variation in porous materials provides a promising platform for all different kinds of advanced applications.

The main aim of this Special Issue of Catalysts is to provide an overview of the most relevant and recent findings in the field of porous materials for advanced applications, which can be applied in (but not limited to) catalysis, adsorption, environmental remediation, sensing, and energy storage applications. Some of the key topics relevant to this Special Issue are: 

  • Synthesis and characterization of porous organic materials (COFs, CTFs, PAFs, POPs, etc.);
  • Synthesis and characterization of porous inorganic materials (zeolite, silica, MOFs etc.);
  • Porous materials for catalysis;
  • Adsorption and gas storage/capture with porous materials;
  • Porous materials for sensing;
  • Porous materials for energy storage;
  • Environmental remediation with porous materials.

A method of phase-transfer water/toluene synthesis was developed to fabricate mesocrystals of Zeolite Socony Mobil-5 (ZSM-5) that contain both meso-/micropores and nanometer crystallites. The construction of a hierarchical architecture from nanozeolites via oriented attachment growth was achieved by a simple phase-transfer water/toluene synthesis by minimizing classical atom-by-atom crystallization. This opens the way to the cheap, highly efficient engineering of zeolitic morphologies. The physicochemical properties of the crystal were revealed by powder X-ray diffraction (XRD), N2 physical adsorption, inductively coupled plasma atomic emission spectroscopy (ICP-AES), scanning electron microscopy (SEM), transmission electron microscopy (TEM), ammonia temperature-programmed desorption (NH3-TPD) and pyridine infrared spectroscopy (Py-IR), indicating that the material has a high specific surface area, mesopore volume and Lewis acid content. The hierarchical ZSM-5 exhibits a prolonged catalytic lifetime in dimethyl ether–methyl ether (DTO) conversion and enhanced selectivity for propylene owing to the enhanced structural properties. The method can be extended to the synthesis of other graded zeolites controlled by the crystallization process and produce crystals comprising traversing mesoporosity and ultrasmall crystallites that are crucial for mass transfer enhancement.

A heterogeneous photocatalyst amenable to catalyze different chemical reactions is a highly enabling and sustainable material for organic synthesis. Herein we report the synthesis and characterization of an azobenzene-based organic π–conjugated porous polymer (AzoCPP) as heterogeneous dual photocatalyst manifesting net-oxidative bromination of arenes and dehydroxylation of boronic acids to corresponding phenols. Hierarchical porosity and high surface area of the nano-sized AzoCPP allowed superior catalyst-substrate contact during catalyses, whereas the inherent structural defect present in the CPP backbone resulted in low-energy sinks functioning as de facto catalytic sites. A combination of these two structure-property aspects of AzoCPP, in addition to the dielectric constant manipulation of the system, led to excellent catalytic performance. The protocols remained valid for a wide substrate scope and the catalyst was recycled multiple times without substantial loss in catalytic activity. With the aid of subsequent control experiments and analytical characterizations, mechanisms for each catalysis are proposed and duly corroborated. Full article
