摘要：

An ESR microscopic imaging on the V4+ and Mo5+ ions Dispersed in the tablets of silica and zeolite carriers was carried out. Distributions of these ions on the surfaces and the cross sections of the catalyst tablets were observed. These results may be a useful information about proper shapes, sizes, and operating conditions of the catalyst particles.
