Öğe FTIR study of the adsorption of ammonia and pyridine on V2O5/MgO catalysts(Marcel Dekker Inc, 1998) Akçay, M; Yurdakoç, M; Tonbul, Y; Yurdakoç, K; Hönicke, DThe adsorption of ammonia and pyridine on the surface of the V2O5/MgO catalysts has been studied for the determination of the Bronsted and Lewis acid sites. The data showed that the catalysts have medium Lewis acidity, but are also weak Bronsted acids, having active hydroxy groups able to interact with pyridine by H-bonding and by protonation. Pyridine is a suitable basic probe for the quantification of the catalysts. 32% V2O5/MgO catalyst is the most acidic catalyst.
