Abstract
Conventional amines and phosphines, such as diethylenetriamine, diphenylpropylphosphine, triethylamine, and tetramethylpiperidine, were grafted or impregnated on the surface of metalated SBA-15 materials, such as Ti-, Al-, and Zr-SBA-15, to generate air-stable solid supported Lewis acid base pairs. The Lewis acidity of the metalated materials before and after the introduction of Lewis bases was verified by means of pyridine adsorption-Fourier transform infrared spectroscopy. Detailed characterization of the materials was achieved by solid-state C-13 and P-31 MAS NMR spectroscopy, low-temperature N-2 physisorption, Xray photoelectron spectroscopy, and energy-dispersive X-ray mapping analyses. Study of their potential interactions with CO2 was performed using CO2 adsorption isotherm experiments, which provided new insights into their applicability as solid CO2 adsorbents. A correlation between solid-supported Lewis acid base pair strength and the resulting affinity to CO2 is discussed based on the calculation of isosteric enthalpy of adsorption © 2018 American Chemical Society
