To evaluate these properties, X-Ray diffraction (XRD) spectroscopy were usedto study the elemental component and the crystalline nature of the materials while the optical properties and structure of the samples were evaluated using UV—vis spectroscopy and field emission scanning electron microscopy (FE-SEM).Finding showed that the Cr-doped SnO2 films were tetragonal in shape.

The structure and the morphology of Si-deposited nanocrystalline diamond were thoroughly studied by X-ray diffraction (XRD), high-resolution electron microscopy (HREM) and Fourier transform infrared (FTIR) spectra.
It also shows that primary particles, not aggregates were coated although there was some extra silicon phase locating around the diamond phase because ALD is a surface chemistry method that would not bind the aggregates together.

Specular reflection FTIR and scanning electron microscopy was employed to observe the morphology of the nickel plated films and the Ni/polymer interfacial structures.

The appearance of stronger peak at 2θ=20o of chtiosan was the evidence of its crystal structure.
Comparatively, the peak of SCCHS became weaker, which suggested that the crystal structure was destroyed.
In the C8-SCCHS, this structure was breached completely and the X-radiation approach beeline.
At pH 6.0, the structure was very compact for interaction between -NH2 and –COOH.

It is demonstrated from the experimental results that Cr3+doping in the ZnIn2S4 photocatalyst had significantly influence on the crystal structure, electron-hole recombination and photocatalytic activity.
The change of the band structure results in the responsive range of the spectrum.
Results and Discussion Crystal Structure The phase and crystallographic structure of the porous ZnIn2S4 were determined by XRD.
This growth tendency of lamellar structures could be explained by the layered feature of hexagonal ZnIn2S4.
The results indicated that the ion-doping in the ZnIn2S4 photocatalyst influenced on the crystal structure, micro-morphology, e--h+ recombination and especially photocatalytic activity.

The comparison of XRD patterns of zeolite and CuO/zeolite displayed that CuO was successfully loaded on the zeolite.The SEM morphology of CuO/zeolite revealed that the cotton shape structure with more loose surface of CuO/zeolite was obtained compared with the SEM morphologies of fly ash and synthesized zeolite.
Characterizations The structures of the zeolite and catalyst samples were characterized using X-ray Diffraction (XRD) instrument (BrukerD8, Bruker, Germany).
It can be seen that the cubic crystal structure of the zeolite has been changed to cotton shape structure with more loose surface.
This is because the suitable calcining temperature and calcining time change the surface structure of the CFA based zeolite .During the process of CuO loading. the more loose surface structure of the catalyst is in favor of the adsorption of small dye molecules on the pore surfaces to facilitate the catalytic reaction.
The SEM image shows that the cubic crystal structure of the zeolite has been changed into cotton shape structure with more loose surface.
