Coherent x-ray diffraction studies of inorganic crystalline nanomaterials

초록

Nanomaterials have been used in many applications because of their enhanced surface-to-volume ratio. They show remarkably different properties when compared to their bulk state and many efforts have been made to enhance the efficiency of nanomaterials. Strain engineering is a growing research field, since strain can alter the properties of materials. Therefore, it is essential to understand the relationship between the structure, including strain, and properties of nanomaterials. There is demand for new characterization tools to image nanomaterials under realistic operating conditions at high resolution, so that nanomaterial efficiency can be improved and new types of nanomaterial can be designed. Bragg coherent X-ray diffraction imaging (BCDI) has emerged as a powerful technique for three-dimensional imaging of nanocrystals at high resolution. BCDI can be used to map the internal lattice displacement field distribution in various crystalline nanomaterials, such as metals and metal oxides, because of its unique sensitivity to the lattice. BCDI, combined with in-situ or operando approaches, is a powerful tool to address scientific questions on nanomaterials and it has opened new areas of scientific research. This chapter introduces state-of-the-art BCDI techniques and reviews recent research on catalysis and energy-related materials, from among many applications to inorganic nanomaterials. © 2023 Elsevier Ltd.
