Induced chirality in metal porphyrin-based biomimetic catalysts promotes ORR activity by enabling spin-polarization effects

Key Points

• To investigate how induced chirality in metal porphyrin catalysts influences oxygen reduction reaction (ORR) activity through spin-polarization effects.
• Utilized metal porphyrin-based catalysts to examine chirality effects on ORR.
• Analyzed electron transfer mechanisms involved in spin-polarization processes.
• Conducted comparative studies with heme-containing proteins to draw parallels.
• Induced chirality significantly improved ORR activity compared to non-chiral systems.
• Spin-polarization effects were confirmed to enhance electron transfer efficiency.
• The findings suggest that chirality can be a key factor in designing more effective biomimetic catalysts for energy applications.
