Special Issue Information

Dear Colleagues,

Advanced porous materials have enormous potential in catalytic applications for their superior thermophysical properties, high specific surface area, low density, and excellent accommodation capability. However, the existing challenges of the design, preparation, and catalytic applications of porous materials urgently need to be addressed.

This Special Issue will cover the recent advancements in porous materials development and their wide catalytic implementations. The Guest Editor encourages submissions in the following areas:

  • The design and preparation of advanced porous materials;
  • Solar photocatalysis;
  • CO2 catalytic reduction;
  • Catalytic recycling of waste plastics;
  • Single atom catalyst;
  • Wastewater recycling and repurposing.

If you would like to submit papers for publication in this Special Issue or have any questions, please contact the in-house Editor, Mr. Ives Liu (ives.liu@mdpi.com).

With the advancement of industrialization and urbanization, the arbitrary emission of sewage containing TC-tetracycline and hexavalent chromium (Cr(VI)) possesses a serious threat to both ecological–environment and public health. However, developing a low-toxicity and cost-effective photocatalyst for the simultaneous elimination of these two pollutants remains a formidable task. This study devised a photocatalytic sample (CSMX-X) comprised of Copper(I) sulfide (Cu2S) and Titanium carbide (Ti3C2) through a simple solvothermal method and applied it to remove TC-tetracycline and Cr(VI). The CSMX-X not only increases the specific surface area from 2.7 m2·g−1 for pure Cu2S to 30.65 m2·g−1, but also effectively addresses the problems of insufficient separation efficiency of photogenerated holes and electrons and low carrier density. The photocatalytic efficiency for an individual pollutant (10 mg·L−1 Cr(VI) or 20 mg·L−1 TC-tetracycline) can reach more than 90%, while the removal efficiency for mixed Cr(VI) and TC-tetracycline pollutants only decreases by 12%. Meanwhile, copper leaching levels under different pH conditions (0.032–0.676 mg·L−1) are considerably lower than the 2 mg·L−1 safety standard set by the World Health Organization. This study provides valuable perspectives for constructing Cu2S-based composite photocatalysts to remove multiple contaminants in real aquatic environments. Full article

Nitrogen oxides (NOx) and chlorinated volatile organic compounds (CVOCs) are major environmental pollutants, posing severe risks to human health and ecosystems. Traditional single-component catalysts often fail to remove both pollutants efficiently, making synergistic catalytic technologies a critical research focus. In this study, a mesoporous HPW-CS-Ce-Ti oxide catalyst, modified with H3PW12O40 (HPW) and chitosan (CS), was synthesized via self-assembly. The optimized 10HPW-CS-Ce0.3-Ti catalyst achieved nearly 100% NO conversion at 167–288 °C and a T90 of 291 °C for CVOC conversion, demonstrating superior dual-pollutant removal. HPW and chitosan facilitated mesoporous structure formation, enhancing mass transfer and active site availability. HPW doping also modulated the Ce4+/Ce3+ ratio, boosting redox capacity and surface-active oxygen species, while increasing acidity to promote NH3 and CVOC adsorption. This study presents a novel catalyst and synthesis method with significant potential for environmental protection and human health. Full article

Ammonia (NH3) emissions from mobile sources pose significant environmental challenges, contributing to air pollution, ecosystem degradation, and climate change. The selective catalytic oxidation of NH3 (NH3-SCO) offers a sustainable solution by converting NH3 into nitrogen and water, yet designing catalysts that balance high efficiency, selectivity, and stability under operational conditions remains a critical challenge. This review provides a comprehensive overview of zeolite-based catalysts, renowned for their high surface area, tunable pore structures, and exceptional hydrothermal stability, which make them ideal for NH3-SCO applications. The review synthesizes recent advancements in catalyst design, emphasizing innovative architecture, the role of zeolite frameworks in active site dispersion, and strategies for optimizing catalytic architectures. Key insights include an enhanced understanding of NH3-SCO reaction mechanisms, progress in mitigating catalyst deactivation caused by poisoning and sintering, and the development of bimetallic and core-shell catalysts to improve performance and durability. Current limitations, including the sensitivity of catalysts to operational environments and scalability issues, are critically analyzed, and potential strategies for overcoming these barriers are proposed. This review highlights the state-of-the-art in zeolite-based NH3-SCO catalysis, offering valuable insights into the fundamental and applied aspects of catalyst design. The findings presented here provide a roadmap for future innovations in environmental catalysis, paving the way for more efficient and robust solutions to ammonia emission control. Full article
