摘要：

Chromium silicalites have been synthesized and characterized using several spectroscopic techniques. I.r. measurements associated with e.p.r. and solid-state n.m.r. data tend to indicate an isomorphous substitution of Si4+ by chromium ions in the silicalite framework. An absorption band at 960 cm-1 on the i.r. spectrum, characteristic of the incorporation in the case of titanosilicalites, is observed. Furthermore, i.r. of adsorbed pyridine reveals the existence of pyridinium ions in the material.
