• Catalyst Activation is well unders<strong>to</strong>od:<br />
2 VOHPO 4 → (VO) 2P 2O 7 + H 2O<br />
• What happens during Catalyst Deactivation?<br />
– Known that Phosphorous is lost<br />
– Analytical measurements show changes in XPS, UV<br />
– But structure <strong>of</strong> deactivated catalyst, deactivation mechanism are not<br />
known<br />
