Oxygen reduction reaction (ORR) is a core electrochemical reaction in the field of energy

conversion and storage, widely used in clean energy technologies such as fuel cells and metal

air batteries. However, the ORR process is often limited by complex dynamic barriers and high

overpotential requirements, which restrict the efficiency improvement of these techniques.

Therefore, developing efficient, stable, and low-cost ORR catalysts has become the focus and

challenge of current research.Although precious metal catalysts such as platinum based

catalysts have high catalytic activity, their high cost limits their large-scale application.Non

precious metal catalysts, as alternative materials, have lower costs, but still need to be further

improved in terms of activity and stability. To address this challenge, our team is committed to

developing a series of new 4e ORR catalysts, including carbon based and non precious metal

oxide based catalysts, with a particular focus on highly active catalysts across the entire pH

range.Research directions include:

1. Developing highly active non-metallic or non precious metal based materials through

heteroatom doping and single atom site design;

2. Using theoretical calculations and machine learning to deduce potential highly active

catalysts, and verifying their performance through experiments;

3. Based on existing membrane reactor and solid-state/semi-solid reactor configurations,

combined with fluid dynamics optimization, the assembly and performance of catalysts are

optimized;

4.By combining industry university research cooperation, the catalyst module will be applied to

practical equipment, and the small-scale and pilot stages will be completed to promote the

engineering application of catalysts.
