Construction of an operando dual-beam fourier transform infrared spectrometer and its application in the observation of isobutene reactions over nano-sized HZSM-5 zeolite

An operando dual-beam Fourier transform infrared spectrometer was developed using a facile method, and was successfully used to characterize the dynamic processes in isobutene aromatization over nano-sized HZSM-5 zeolite under real reaction conditions.
