Five different samples are studied to characterize spectroscopically cobalt in and out of the lattice: two CoAPO-5 samples of different quality, CoAPO-5 gel, Co2+-impregnated AlPO4-5 and Co2+-impregnated alumina. Characterizations with diffuse reflec

CoAPO-34 co-crystallizes easily with CoAPO-5. Factors directing the structure of the final product are the cobalt and template content of the gel, the mixing temperature of the gel and the synthesis temperature. Gel compositions for CoAPO-5 are expre

CoAPO-n with chabazite (CHA) topology crystallizes competitively with CoAPO-5. Insight in the co-crystallization is obtained by Diffuse Reflectance Spectroscopy (DRS). Wet gels with variable template content are analyzed as such and after centrifugat

Diffuse reflectance spectroscopy (DRS) is an excellent technique for the investigation of the synthesis process of CoAPO-5. The DRS intensities increase concomitantly with the crystallinity during synthesis. DRS is also useful in the characterization

An iterative computer program for the optimization of ESR powder spectra is described. Its applicability to metal clusters is demonstrated. Spectra of silver and sodium clusters in zeolites are generally recognized to be composed of two isotropic sig
