Answer to Question #200286 in General Chemistry for rat

Question

Briefly discuss why X-ray diffraction is inadequate for the study of Zeolites and suggest two techniques that would be more informative, rationalising your answer.  

Answer 1

Ans:-Study of zeolites via synchrotron X-ray powder diffraction is an essential tool in understanding their applications in gas storage and separation and catalytic chemistry.

Because X-rays have wavelengths similar to the size of atoms, they are useful to explore within crystals. Thus, since X-rays have a smaller wavelength than visible light, they have higher energy. With their higher energy, X-rays can penetrate matter more easily than can visible light.

Two techniques are

Powder and single crystal diffraction 

Single-crystal X-ray Diffraction is a non-destructive analytical technique which provides detailed information about the internal lattice of crystalline substances, including unit cell dimensions, bond-lengths, bond-angles, and details of site-ordering.

Powder diffraction is a scientific technique using X-ray, neutron, or electron diffraction on powder or microcrystalline samples for structural characterization of materials. An instrument dedicated to performing such powder measurements is called a powder diffractometer.
