Abstract

This paper mainly studies the preparation of Pt-based bulk combustion catalysts using cordierite honeycomb ceramics as the substrate, and chemical plating technology to directly load precious metal Pt on the sensitized and activated ceramics. Formaldehyde was used as the reaction gas for performance testing of the combustion catalytic activity of the catalyst. The XRD and SEM results have shown that the Pt particles were loaded on the face of cordierite. The effect of formaldehyde purification is significantly affected by factors such as the initial concentration of formaldehyde in the closed space, environmental humidity, and catalyst calcination temperature.
