Abstract: Several nano structured materials are produced using solution processing methods which includes nano metals, oxides and porous materials such as zeolites, aluminophosphates and metal-organic frameworks. While these materials are widely used for a range of applications, it is important to understand the growth processes of these materials and structure at various stages. To understand the reactivity under dynamic conditions, it is necessary to employ techniques that provide sufficient time resolution to determine the structure under operating conditions. X-ray techniques in particular using Synchrotron Radiation offers many such possibilities. A detailed discussion of how the combination of X-ray techniques provide detailed information of size, shape, short, medium and long range structures of nano structured materials by taking examples from metal nano particles and crystalline zeolite systems. Advantages and disadvantages of these techniques will be discussed in detail.
