XANES EXAFS

The electronic structure of the spinel type compound NiCo204 has been investigated by XANES, EXAFS, and Ni Mdssbauer studies. On the basis of the derived cation valencies, the octahedral and tetrahedral site occupancies as well as the formula in standard notation for spinel compounds could be delineated [25]. 

The results confirm that the novel metal nitrate conversion method using nitric oxide in place of air advocated by Sietsma et al. in patent applications WO 2008029177 and WO 2007071899 leads to, after activation in H2, catalysts with smaller cobalt crystallites, as measured by EXAFS and hydrogen chemisorption/ pulse reoxidation. In spite of the lower extent of cobalt reduction for H2-activated nitric oxide calcined catalysts, which was recorded by TPR, XANES, EXAFS,...

Introduction of PPh2CHMc2 into Ni(CO)4-loaded NaY led to the formation of Ni(CO)3PPh2CHMe2, as evidenced by XANES, EXAFS, NMR, and IR spectroscopies (85). 

As may be concluded from screening the literature, the combination of various physicochemical techniques (TEM, STEM, HRTEM, HRSTEM, XRD, BET Nj adsorption, XANES, EXAFS) allows quite comprehensive characterization of mesoporous solids with nanoparticles. Nevertheless, when particle size distribution is questionable and important. X-ray and neutron scattering techniques (SAXS, ASAXS, SANS) should be more widely used for better understanding the material properties.
