Special Issue Information

Dear Colleagues,

In this Issue of Nanomaterials, we specifically examine the application of solid nanocatalysts in the fields of energy and environment, with a particular emphasis on their potential for degrading pollutant gases. As environmental pollution challenges intensify, the need for effective catalytic technologies has become increasingly critical. Various technologies present novel opportunities for the design and performance enhancement of nanocatalysts.

Nanostructured and multifunctional solid nanocatalysts significantly improve the efficiency and selectivity of chemical processes, resulting in superior performance in practical applications. For instance, plasma-assisted catalysis has demonstrated efficacy in the degradation of pollutant gases, including NOx and VOCs, thereby making substantial contributions to environmental protection.

In this special Section of our journal, we present innovative research findings from various research teams, encompassing a diverse array of topics such as plasma activation technology for nanocatalyst preparation, performance characterization, and its applications in energy conversion and environmental protection. These studies illustrate the versatility of technologies and their pivotal role in enhancing nanocatalyst performance. Through these contributions, readers will gain insights into the latest advancements in the domain of nanostructured and multifunctional solid catalysts, as well as their potential application for sustainable chemical processes.

We anticipate that this Special Issue will serve as a valuable resource for researchers and industry professionals, providing thought-provoking perspectives on the future of nanocatalytic technology. It is our hope that this journal will inspire greater engagement from researchers in the expansive field of plasma technology and catalysis, fostering collaboration toward the advancement of environmental remediation technologies.

A new type of CeO2-modified AgCl catalyst (CeO2/AgCl) was prepared by a one-step method, which efficiently inhibits the recombination of photogenerated carriers. During the visible-light degradation process, this catalyst exhibited excellent and stable performance. It could not only effectively degrade rhodamine B (RhB), methyl orange (MO) and crystal violet (CV) but also maintain excellent activity under different environmental conditions. In the RhB degradation experiment in particular, the CeO2/AgCl-30 composite with the optimal proportion had a degradation rate 5.43 times that of pure AgCl in the seawater system and 9.17 times that of pure AgCl in the deionized water condition, while also showing excellent stability. Through characterization tests such as XRD, XPS and ESR, its crystal structure, elemental composition and so on were analyzed. Based on the characterization results, the CeO2/AgCl composite showed a relatively wide light absorption range and a relatively high photo-induced charge separation efficiency. Meanwhile, it was inferred that the main active species in the reaction process were ·O2⁻ and ·OH. Finally, based on its electronic band structure, an S-scheme heterojunction structure was proposed.

Volatile organic compound (VOC) emissions have become a critical environmental concern due to their contributions to photochemical smog formation, secondary organic aerosol generation, and adverse human health impacts in the context of accelerated industrialization and urbanization. Catalytic oxidation over perovskite-type catalysts is an attractive technological approach for efficient VOC abatement. This review systematically evaluates the advancements in perovskite-based catalysts for VOC oxidation, focusing on their crystal structure–activity relationships, electronic properties, synthetic methodologies, and nanostructure engineering. Emphasis is placed on metal ion doping strategies and supported catalyst configurations, which have been demonstrated to optimize catalytic performance through synergistic effects. The applications of perovskite catalysts in diverse oxidation systems, including photocatalysis, thermal catalysis, electrocatalysis, and plasma-assisted catalysis, are comprehensively discussed with critical analysis of their respective advantages and limitations. It summarizes the existing challenges, such as catalyst deactivation caused by carbon deposition, sulfur/chlorine poisoning, and thermal sintering, as well as issues like low energy utilization efficiency and the generation of secondary pollutants. By consolidating current knowledge and highlighting future research directions, this review provides a solid foundation for the rational design of next-generation perovskite catalysts for sustainable VOC management.
