Abstract
A pulse chemisorption/reaction system in combination with Fourier transform infrared spectrometer equipped with a diffuse reflectance infrared Fourier transformed spectroscopy (DRIFTS) reaction cell and online mass spectrometer is described in detail. Such a system provides an approach to effectively suppress the interference of the gas-phase reactants to the vibrational signals of surface adsorbates during the operando DRIFTS measurements and, thus, allows for in situ and real-time monitor of surface species on catalyst surfaces during chemisorption/reaction processes. Employing this system, we successfully acquired DRIFTS spectra that clearly demonstrate surface species formed by propylene chemisorption and reaction on octahedral Cu2O nanocrystals; we also observed simultaneous chemisorption of CO on top, twofold, and threefold bridged sites of Pd nanoparticles supported on SiO2 upon the collision of CO prior to the saturation of strongly bound sites and the transformation of weakly bound CO(a) into strongly bound CO(a) during the dynamic chemisorption-desorption processes.

Abstract
A new hybrid spherical structure α-Fe(2)O(3)@SiO(2)@Au with a size of about 141 nm was designed, with a hematite cubic core surrounded by a thick silica shell and further decorated with gold nanoparticles. The monodisperse α-Fe(2)O(3)@SiO(2) spheres were first prepared by a sol-gel process based on the modified Stöber method. Subsequently, the surface of the α-Fe(2)O(3)@SiO(2) particles was functionalized by-NH(2) functional groups. The electrostatic attraction of -NH(2) groups will attach the negatively charged Au nanoparticles to the amino-functionalized α-Fe(2)O(3)@SiO(2) nanospheres in order to prepare α-Fe(2)O(3)@SiO(2) monodisperse hybrid spheres. The M(H) hysteresis loop for α-Fe(2)O(3)@SiO(2) and α-Fe(2)O(3)@SiO(2)@Au spheres indicates that the nanocomposite spheres exhibit superparamagnetic characteristics at room temperature. The optical properties and the application of these hybrid nanocomposites as catalysts for the conversion of CO to CO(2) have also been studied.
