Special Issue Information

Dear Colleagues,

Minerals are widely distributed across nature, and are often used as a support for catalysts due to their special physical–chemical properties. Generally, most minerals used as catalyst supports have a layered structure, which can be roughly divided into kaolinite, smectite, vermiculite, hydromica, fiber rod stone, etc. In this structure, octahedrons and tetrahedrons can form different layered structures with adjustable ratios, resulting in the controlled pore sizes, surface areas and surface groups. Moreover, after acidification, purification, pillar and calcification, minerals will easily allow reactants to diffuse, transfer and absorb, which is favorable for compounding with catalysts and promotes the efficiency of catalytic treatment for heavy metals, organic pollutants and gas molecules. Thus, developing mineral-based catalysts is an important part of green catalytic technology that should be noticed in environment protection, energy conversion and other green chemical fields. This Special Issue is dedicated to collecting original research on environment protection and energy conversion, and original research, reviews and perspective articles are welcome. All the papers should relate to the following topics:

  • Synthesis and modification of mineral-based catalysts;
  • Catalytic pollutant degradation (including air and water pollution treatment);
  • Catalytic water splitting and H2 production;
  • Catalytic CO2 reduction;
  • Catalytic conversion of biomass.

Membrane separation has been widely utilized to eliminate pollutants from wastewater. Among them, a polyacrylonitrile (PAN) ultrafiltration (UF) membrane has presented outstanding stability, and distinguished chemical and thermal properties. However, UF membranes inevitably incur fouling issues during their operation procedure caused by contaminant adhesion on the membrane surface, which would restrict the operational efficiency and increase the maintenance cost. The conventional physical and chemical cleaning is not an effective technique to reduce the fouling due to the additional chemical addition and inevitable structure damage. Recently, UF membranes combined with photocatalytic materials are suggested to be a useful approach to conquer the membrane fouling issues. Herein, TiO2 nanoparticles were utilized to blend with a PAN casting solution for fabricating a composite UF membrane via a phase inversion method. With a certain TiO2 addition, the obtained membranes presented an enhancement of hydrophilicity, which could promote the water permeability and antifouling performance. The optimized M3 membrane prepared with 15.0 wt% PAN and 0.6 wt% TiO2 exhibited an excellent water permeability up to 207.0 L m−2 h−1 bar−1 with an outstanding 99.0% BSA rejection and superior antifouling property. In addition, the photocatalytic TiO2 nanoparticles endowed the M3 membrane with a remarkable self-cleaning ability under the UV irradiation. This facile construction method offered new insight to enhance the UF membrane separation performance with an enhanced antifouling ability. Full article
