Electron probe microanalysis, metal oxides

The typical deactivation curves plotted in Figure 8 depict the poisoning of Johnson Matthey platinum metal oxidation catalyst by lead and phosphorus. A section of the spent catalyst was subjected to electron probe microanalysis (Figure 9) the lead and phosphorus density photographs were obtained by monitoring back reflected x-rays. Phosphorus accumulated on the periphery of the washcoat at the gas-solid interface, whilst lead appeared to be more evenly distributed throughout the... [Pg.69]
