Catalysts with slow, passive release of alkali ions

Patent

Description

Described is a method of slowly releasing a catalyst for, inter alia, the purpose of soot oxidation in a particulate filter. An example method includes incorporating an alkali metal oxide in a glass. Slow leaching of the alkali from the glass provides a means to gradually deliver the catalyst over extended periods. Additionally, the example method includes increasing the amount of alkaline metal ions that may be leached from the glass.
