The hydrothermal stability of CuCe/BEA catalyst is improved by its silanization for selective catalytic reduction of NO_x with NH₃ (NH₃-SCR). The results indicate that the silanization modification effectively enhances the catalytic activity of CuCe/BEA after the hydrothermal treatment due to significantly inhibit the hydrolysis of Si-O-Al bonds from the BEA skeleton to maintain structural integrity, revealed by X-ray diffraction (XRD), scanning electron microscope (SEM) and ²⁷Al nuclear magnetic resonance (²⁷Al NMR). More complete skeleton structure of CuCeSi/BEA catalyst results in the formation of more acid sites after the hydrothermal treatment, confirmed by NH₃-temperature programmed desorption (NH₃-TPD) and in situ diffuse reflectance infrared transform spectroscopy (in situ DRIFTS). Moreover, H₂-temperature programmed reduction (H₂-TPR) and X-ray photoelectron spectrum (XPS) show that silanization is beneficial to facilitate the dispersion of active copper ions after the hydrothermal treatment. Therefore, more acid sites and highly dispersed Cu species together contribute to higher hydrothermal stability of silanized CuCeSi/BEA than CuCe/BEA catalyst.
