Special Issue Information

Dear Colleagues,

The adoption of advanced oxidation–reduction technologies for the separation and removal of pollutants from wastewater has garnered significant attention. While environmental functional materials can effectively achieve the catalytic degradation of contaminants, challenges such as high costs, significant secondary pollution risks, complex reaction mechanisms, low catalyst reusability, and engineering difficulties persist. This Special Issue, titled “Separation and Remediation of Environmental Pollutants Using Functional Materials”, aims to advance research in catalytic oxidation mechanisms, catalytic reduction mechanisms, environmental interference, the catalytic degradation of emerging contaminants, photocatalysis, electrocatalysis, non-thermal plasma, persulfate oxidation, Fenton and Fenton-like systems, peracetic acid oxidation, and engineering applications of catalytic materials.

This issue will present cutting-edge research on catalytic redox separation and degradation of environmental pollutants using functional materials. Topics of interest include, but are not limited to, the following:

  • Catalytic oxidation technologies;
  • Catalytic reduction technologies;
  • Metal oxides;
  • Inorganic catalysts;
  • Carbon-based catalytic materials;
  • Metal–organic frameworks (MOFs) and derivatives;
  • Covalent organic frameworks (COFs);
  • Engineering applications.

This work aims to adsorb CO and CO2 using a low-cost biogenic waste (bone) as a platform for the in situ growth of HKUST-1, employing two methodologies. The synthesized composite materials, BMOF2 and BMOF3, exhibited functional, textural, and structural characteristics that were modulated by the MOF growth pathway. SEM, RXD, FTIR, XPS, and the N2 adsorption–desorption isotherm confirmed the growth of HKUST-1. Both methodologies yield the same MOF, but differ in surface area and shape. The relative and total coverage percentages were determined, as well as the apparent selectivity at a fixed time, establishing direct correlations between the structural and textural differences in the materials and their dynamic performance in the presence of both gases. Although the adsorption capacities obtained do not exceed those of other MOFs, the results from BMOF2 and BMOF3 demonstrate that the efficiency of an adsorbent depends not only on its capacity but also on its technological feasibility, including rapid processing and high capacities. The combination of abundant availability, a simple, sustainable, and reproducible synthetic route, and competitive performance makes these compounds viable alternatives for large-scale applications. Incorporating HKUTS-1 into bone as a functional material is a promising approach to developing new compounds for gas capture in the treatment of gas streams. Full article
