Elucidating d-d orbital hybridization in metal-doped MnO2 for N2O formation inhibition mechanism in NH3-SCR

Key Points

• To investigate the role of d-d orbital hybridization in metal-doped MnO2 for inhibiting N2O formation during NH3-SCR.
• Analyzed catalytic performance of manganese-based oxides in NH3-SCR
• Examined effects of metal doping on hybridization and catalytic activity
• Conducted experiments below 200 °C to assess low-temperature catalysis
• Metal-doped MnO2 showed enhanced catalytic performance
• Dehydrogenation was notably inhibited, affecting N2O production
• Findings suggest a significant relationship between orbital hybridization and catalytic efficiency
