| Abstract: | The adsorption of NH3 on Cr–Mo and Cr–Mo–Te catalysts has been investigated by IR spectroscopy. It is shown that there are both electron acceptor and proton donor acid centers on the surface of these catalysts. The introduction of tellurium into a Cr–Mo catalyst decreases adsorption on the electron acceptor centers.
