%X An awareness of increasing climate and health problems has driven the development of new functional and affordable soot-oxidation catalysts for stationary sources, such as fireplaces. In this study, Al(OH) 3, water glass and acidic aluminium phosphate binder materials were mixed with soot-oxidation catalysts. The effect of the binder on the performance of the Ag/La-Al 2O 3 catalyst was examined, while the Pt/La-Al 2O 3 catalyst bound with Al(OH) 3 was used as a reference. Soot was oxidised above 340 ˇăC on the Ag/La-Al 2O 3 catalyst, but at 310 ˇăC with same catalyst bound with Al(OH) 3. The addition of water glass decreased the catalytic performance because large silver crystals and agglomeration resulted in a blockage of the support materialˇŻs pores. Pt/La-Al 2O 3 bound with Al(OH) 3 was ineffective in a fireplace environment. We believe that AgO x is the active form of silver in the catalyst. Hence, Ag/La-Al 2O 3 was shown to be compatible with the Al(OH) 3 binder as an effective catalyst for fireplace soot oxidation. View Full-Tex
