Special Issue Information

Dear Colleagues,

Mesoporous materials, distinguished by their unique structural attributes and high surface energy characteristics, are exceptionally well-suited for pollutant removal applications. These materials encompass a diverse range of nanomaterials with remarkably large specific surface areas, including one-dimensional materials with elevated aspect ratios, two-dimensional membrane materials exhibiting high porosity, and porous materials featuring multi-level structures. Whether composed of organic, inorganic, or hybrid compositions, these materials demonstrate tailored adsorption capacities for various adsorbents based on their intrinsic structures and surface properties. Moreover, the adsorption method is cost-effective, efficient, and minimizes secondary pollution, making it a subject worthy of extensive study.

This Special Issue is dedicated to ‘Mesoporous Materials for Pollutant Removal’. The scope encompasses, but is not confined to, the following areas:

  1. Design and synthesis of mesoporous materials.
  2. Research on surface coatings and composite materials.
  3. Evaluation of adsorption properties of innovative adsorbent materials.
  4. Exploration of correlations between mesoporous structures, surface characteristics, and adsorption properties.
  5. Research on adsorption kinetics, thermodynamics, and mechanisms.

We warmly invite you to contribute to this significant discourse and advance our understanding of mesoporous materials in environmental remediation.

Oxygenated volatile organic compounds are key precursors of secondary photochemical pollutants. To enhance their removal, NaY–zeolite was modified with nano-sized metals (Fe, Ti, Si, or Ce) using impregnation and sol–gel methods. Dynamic adsorption experiments were conducted to evaluate the adsorption of ethanol, acetaldehyde, and ethyl acetate under various condition modifications, including of the impregnation concentration, treatment time, and calcination temperature. The structural and surface properties of the modified zeolites were characterized by N2 adsorption–desorption isotherm, X-ray powder diffraction (XRD), Scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), and Fourier transform infrared spectroscopy (FT-IR) analyses. The results indicated that the metal-loaded zeolites exhibited significantly higher adsorption capacities than the unmodified NaY–zeolite. Among them, silicon-modified zeolite showed the best performance, with its adsorption capacities for ethanol, acetaldehyde, and ethyl acetate increasing from 32.4, 72.4, and 123.0 mg·g−1 to 49.82, 88.94, and 207.02 mg·g−1, corresponding to improvements of 37%, 23%, and 70%. The optimal modification conditions involved the use of silicon as the modifier with a 7% impregnation concentration, a 12 h impregnation time, and calcination at 350 °C; the zeolite modified under these conditions was characterized by a good adsorption capacity and low preparation cost. This study suggests newly designed adsorber materials suitable for highly efficient treatment of oxygenated volatile organic compounds. Full article
