IR spectroscopic determination of protonation heats of bases on catalyst surfaces
Tóm tắt
IR spectra of pyridine adsorbed on zirconium phosphate and zeolite HNaY were studied at temperatures of 400–500 K. Protonation heats of pyridine determined on the OH groups of zirconium phosphate and zeolite HNaY having theυOH at 3640 cm−1, are 65±6.0 and 172±16 kJ/mol, respectively.
