The Individual

The prepared, modified, and coated alumina surfaces were characterized by infrared spectroscopy (FTIR) to investigate the surface properties of the individual and double modified samples. FTIR helps in reporting the changes occurred in hydroxyl groups as well as the structure changes as a result of thermal treating, hydrothermal treating, silylation treating, alkali metal treating, coating, and bonding with polymer. FTIR spectroscopy represents the strength and abundance of surface acidic OH which determine the adsorption properties of polar and nonpolar sorbents. Generally, all treated samples exhibit decrease of OH groups compared with those of parent ones producing alumina surfaces of different adsorptive powers.

Pd Catalysts

It has been experimentally found that ceria supports with strong basicity and high concentration of O-vacancies significantly enrich the electron density of Pd catalysts and accelerate the step of oxidative addition for C–C coupling reaction. The FTIR and XPS provide strong evidence supporting for this interfacial effect.
