Special Issue Information

Dear Colleagues,

The emission of pollutants and greenhouse gases in the industrial sector causes significant damage to the environment, including the atmosphere, soil, and water, and poses a threat to human health, becoming an increasingly complex and serious issue. Thus, controlling these emissions has become a focal point of research across various disciplines. The findings of such research not only contribute to theoretical advancements and technological innovations but also provide a foundation for policymaking and the achievement of sustainable development goals. In recent years, polymers have gained considerable attention in pollution and carbon reduction efforts due to their high specific surface area and porosity. Additionally, by modifying their structures and chemical properties, polymers can be tailored for high selectivity in removing specific substances. Moreover, polymers can be combined with other materials to form composites, introducing new characteristics and enhancing removal efficiency. Overall, polymers have demonstrated significant potential and broad application prospects in pollutant and greenhouse gas removal, making them crucial materials for environmental protection and sustainable development. Therefore, the development of high-performance, environmentally friendly polymers is key to addressing environmental pollution in the industrial sector.

Topics of interest for the Special Issue include, but are not limited to, the following:

  • Key innovative technologies for source reduction in pollution and carbon in key industries;
  • New pathways and catalytic technologies for CO2 conversion;
  • New technologies and materials for pollutant reduction using renewable energy sources;
  • Improvement of efficiency and reduction of energy consumption of various industrial processes based on reaction modulation and reconfiguration;
  • Thermochemical disposal, conversion and utilization of various types of inorganic/organic wastes and industrial emissions.

The temperature at which pollutants are treated varies across different industrial processes. To address the high cost of raw materials for MOFs and the low efficiency of Hg0 removal in low-temperature environments, a series of MIL-101(Cr)-derived carbon matrix composite materials were prepared by combining MIL-101(Cr) with biomass and multiple metals. These materials were synthesized through a sol-gel method followed by carbonization. This study investigates the effects of composite ratios and adsorption temperatures on Hg0 removal, utilizing XRD, BET, and other characterization techniques to elucidate the mercury-removal mechanism of the PDC-MIL composite materials. The results indicate that MIL101(Cr) significantly influences the formation of the gel skeleton. When the composite ratio of MIL-101(Cr) to biomass is 1:1, the material exhibits an optimal pore structure, leading to high Hg0 removal efficiency over a wide temperature range. The removal of Hg0 by these composite materials involves both physical adsorption and chemisorption. Low temperatures favor physical adsorption, while high temperatures promote chemisorption. The sol-gel composite method facilitates cross-linking polymerization between MOFs and SiO2, enabling better pore structure connectivity with biomass and MOFs, thereby optimizing the poor pore structure observed after pyrolysis. Consequently, the improved pore structure enhances physical adsorption at low temperatures, mitigates desorption at high temperatures, and increases the contact probability of Hg0 with active sites within the pores, significantly improving the mercury-removal ability of the material across a broad temperature range.
