Abstract: GeFeAPO-5 molecular sieve was synthesized in the system of fluoride ions. After adsorption of pyridine the IRspectra showed the presence of both Brönsted and Lewis acid sites. GeFeAPO-5 molecular sieve was identified by means of X-ray diffraction analysis, determination of the unit cell parameters, electron probe, infrared spectra, Mössbauer spectroscopy, electron paramagnetic resonance spectrum, high resolution magic-angle-spinning solid state 31P and 27Al nuclear magnetic resonance. The results showed Fe and Ge entered into the GeFeAPO-5 framework.
