Two-dimensional secondary ion mass spectrometry (SIMS) imaging provides evidence that the catalytic activity of calcium in the gasification of calcium-loaded graphite involves the dissociative chemisorption of oxygen on calcium oxide particles and/or calcium on cation exchange sites to form reactive surface complexes. The work reported here extends the study to three-dimensional imaging. The results confirm the two-dimensional observations.
