Overview

Bimetallic catalysts show improved HCHO oxidation in protozeolite, indicating enhanced indoor air quality potential.

Key Points

  • This research aims to enhance indoor air quality by improving the efficiency of formaldehyde oxidation using innovative catalysts.
  • Used a coimpregnation method to anchor Pt-CeOx nanoparticles in protozeolite.
  • Analyzed the structural characteristics with AC-HAADF-STEM and evaluated performance through in situ DRIFTS and DFT calculations.
  • Assessed the catalyst's stability and activity for HCHO oxidation at room temperature.
  • Achieved complete conversion of HCHO with the optimized Pt/CeOx/PZ catalyst.
  • Maintained stability and activity for over 24 hours at room temperature.
  • Demonstrated enhanced electron density in Pt sites due to the presence of CeOx, facilitating HCHO oxidation.
