Special Issue Information

Dear Colleagues,

Porous materials having inorganic or hybrid frameworks delimiting a regular porous structure are promising candidates for different applications, such as catalysis, separation, ion exchange, gas storage, molecular decontamination, etc. In particular, microporous materials and mesoporous materials have exciting properties due to the size of their pore openings, their large specific surface areas and pore volumes. Recently, another class of porous materials, called hierarchical porous materials, has emerged. These materials contain at least two different types of interconnected porosities (micro/mesopores, etc.), which are known, for example, to improve the performances of the microporous counterpart thanks to an efficient mass transfer kinetics through mesopores. Porous materials are of great scientific importance from a fundamental point of view due to their ability to interact with atoms, ions, and molecules on their sizeable interior surfaces and porosity. This growing interest in porous materials has led to progress in characterization techniques and modelling studies to better understand the structure/property relationships, in order to improve the design of tailor-made porous materials with high performances. This Special Issue proposes a state-of-the-art in recent advances made in the field of inorganic and hybrid porous materials, with a focus on:

  •       New methods for the synthesis of porous materials and the control of particle size and morphology
  •       Methods for textural and structural characterization of porous materials
  •       Shaping of porous materials (films, pellets, beads, extrudates, etc.)
  •       Known applications:
          -Molecular decontamination (water and air treatments)
          -Gas storage
          -Ion-exchange
          -Molecular sieving (molecule separation, gas purification)
          -Catalysis (biomass conversion, etc.)
  •       Emerging applications:
          -Energy storage
          -Sensors
          -Health (biomedical applications)
          -Photovoltaic

Time-stability of LTA zeolite formed by hydrothermal method with or without the action of ultrasonic irradiation was investigated by X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM). The results show that 6 months after the synthesis by hydrothermal process with continuous sonication, LTA evolves into a more stable sodalite, whereas no differences are detected 12 months after LTA synthesis by conventional pre-fused hydrothermal process. These data confirm that using the two approaches, different mechanisms control both zeolite crystallization and time-stability of the newly-formed mineral at solid state. The results are particularly important in the light of the synthetic zeolite application. Full article

Abstract: Using polyethylene glycol (PEG) as a mesoporous soft template, a series of hierarchically porous ZSM-5 zeolites were prepared. Infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and transmission electron microscopy (TEM) characterization results demonstrated the resultant zeolites contain adjustable micro-mesoporous structure. Moreover, we investigated the zeolites’ application in the alkylation of phenol with tert-butanol. Due to the mesoporous structure improving diffusion lengths and reactivity in the reaction of large molecules, the phenol conversion can reach 96.5% and the selectivity to 2,4-di-TBP is as high as 53.9% for the alkylation of phenol with tert-butanol.
