Description
Summary:Although the local 3D atomic arrangement around specific active-site atoms in a functional materials is very important to reveal the origin of the functionality, the analysis of the atomic arrangement has not been possible so far because this local structure has no translational symmetry. Recently the analysis of this kind of local 3D atomic arrangement around specific atoms which has no translational symmetry has become possible with several atomic-resolution holographies and related techniques, which have been developed in Japan. Hence a project of "3D Active-Site Science" of JSPS Grant-in-Aid for Scientific Research on Innovative Areas has started. This review describes the characteristic of these new local 3D atomic imaging techniques and the achievements of the project especially two representative results and new notation system of active-site.
