Abstract

A deactivated (aged under redox-cycled model TWC feed-stream) Pd/Ce&lt;SUB&gt;0.68&lt;/SUB&gt;Zr&lt;SUB&gt;0.32&lt;/SUB&gt;O&lt;SUB&gt;2&lt;/SUB&gt; catalyst is remarkably reactivated when subjected to a high temperature oxidising treatment whereas this effect is only marginal for Pd/Al&lt;SUB&gt;2&lt;/SUB&gt;O&lt;SUB&gt;3&lt;/SUB&gt;, which indicates the key role of such treatment in restoring the Pd–Ce&lt;SUB&gt;0.68&lt;/SUB&gt;Zr&lt;SUB&gt;0.32&lt;/SUB&gt;O&lt;SUB&gt;2&lt;/SUB&gt; interactions leading to highly active catalysts.
