A high-performance cryptomelane-type MnO2 synthesized by one-step hydrothermally method for low-temperature NO conversion with NH3

Key Points

• Low-temperature NO conversion efficiency was significantly improved with the synthesized manganese dioxide.
• Specifically, the catalyst demonstrated a remarkable conversion rate of over 90% at temperatures below 200°C.
• Assessment utilizes a one-step hydrothermal synthesis method to produce the cryptomelane-type structure.
• This may enable better results for air quality control, leveraging ammonia as a reducing agent.
