Special Issue Information

Dear Colleagues,

Catalysts are pivotal in tackling global energy challenges and environmental issues, being essential for energy conversion and pollution control. This Special Issue, entitled "Advanced Catalysts in Environmental Purification", serves as a hub for the latest scientific discoveries and technological advancements in catalysis. Our objective is to compile research that investigates state-of-the-art catalyst design, synthesis, and application, highlighting their significant impact on improving energy efficiency and reducing environmental pollution.

We welcome submissions focusing on the development and application of advanced catalysts across various topics, including but not limited to heterogeneous and homogeneous catalysis, photocatalysis, electrocatalysis, and biocatalysis. We are especially keen on studies that tackle catalyst stability, selectivity, and scalability, as well as those presenting innovative approaches to waste minimization and resource regeneration.

This Special Issue aims to establish a platform where scientists, engineers, and industry experts can share insights, exchange ideas, and collaborate. Our ambition is to catalyze further innovation and advance the development of catalysts that will substantially contribute to a cleaner, more energy-efficient, and sustainable future.

The steel manufacturing industry is a major source of global air pollution, with sintering processes contributing over 70% of emissions, primarily carbon monoxide (CO), a significant uncontrolled pollutant. This study explores Mn-Cu bimetallic catalysts as a cost-effective and environmentally friendly alternative to noble metal-based systems, addressing the urgent need for efficient CO oxidation catalysts. Mn-Cu catalysts with different Mn/Cu molar ratios were synthesized via hydrothermal methods and systematically characterized using XRD, XPS, BET, H2-TPR, etc., to assess their physicochemical properties and catalytic performance. The Mn4Cu1 catalyst demonstrated the highest CO oxidation activity, achieving complete conversion at 175 °C. This performance is attributed to its optimal Mn/Cu molar ratio, high specific surface area, abundant oxygen vacancies, and superior redox properties. The catalyst’s enhanced performance is further supported by its low reduction temperature and high Mn3+ and Cu+ content, which promote efficient electron transfer and oxygen activation. These findings highlight the crucial role of Mn/Cu molar ratios in optimizing catalytic performance and offer valuable insights for designing high-efficiency, low-cost catalysts to reduce CO emissions in industrial applications.
