2025-10-16
In catalytic applications for exhaust gas purification, the development trends of catalysts are mainly reflected in the following aspects:
Catalyst Material Innovation:
Applications of Nanomaterials: Due to their unique physicochemical properties, nanomaterials hold great promise for wide-ranging applications in the field of catalysis. For example, nanomaterials such as nano-TiO₂, nano-ZnO, and nano-NiO exhibit excellent photocatalytic performance or outstanding catalytic activity, making them suitable for industrial waste gas purification processes, including photocatalytic oxidation for the degradation of organic pollutants.
Development of Metal-Organic Framework Materials (MOFs): MOFs are a class of metal-organic compounds characterized by high specific surface area and porous structures. They offer advantages such as high activity, high selectivity, and ease of recovery. In industrial waste gas purification, their applications primarily focus on denitration and desulfurization.
Research and development of composite materials: By combining two or more materials with different properties, it’s possible to leverage the advantages of each material. For example, combining metal oxides with activated carbon can enhance both the adsorption performance and catalytic activity of a catalyst, holding great potential for applications in industrial exhaust gas purification.
Synergistic Control of Multiple Pollutants: Industrial exhaust gases typically contain a variety of pollutants. In the future, we will develop synergistic control technologies tailored to this characteristic. For example, we will integrate technologies such as denitration, desulfurization, and VOCs removal to achieve highly efficient pollutant removal, thereby enhancing the overall efficiency and effectiveness of exhaust gas purification.
Application of Intelligent Control Systems: With the rapid advancement of technologies such as the Internet of Things and big data, intelligent control systems will be developed to enable automated and intelligent management of catalytic purification processes. By continuously monitoring exhaust gas emissions, collecting and analyzing relevant data, and leveraging this data to optimize catalyst operating parameters, we can achieve precise control over the purification process, enhance exhaust gas purification efficiency, and reduce operational costs.
In-depth study of catalytic reaction mechanisms: A deeper understanding of green catalytic reaction mechanisms will provide a more robust theoretical foundation for the design and development of new catalysts. For example, studying the mechanism of selective catalytic reduction (SCR) can help enhance the NOx selectivity of catalysts, thereby enabling better design and optimization of catalysts and improving their performance and effectiveness.
Reducing Costs and Enhancing Stability: On the one hand, addressing the issue of high preparation costs for new green catalytic materials, we will focus on lowering costs and improving economic benefits to facilitate their large-scale industrial applications. On the other hand, we will enhance the stability of catalysts by optimizing their structure and composition, enabling them to better withstand various complex conditions in practical applications and extending their service life.
