Nanotechnology is the manipulation or self-assembly of individual atoms, molecules, or molecular clusters into structures to create materials and devices with new or vastly different properties.
Nanotechnology can work from the top down (which means reducing the size of the smallest structures to the nanoscale e.g. photonics applications in nanoelectronics and nanoengineering) or the bottom up (which involves manipulating individual atoms and molecules into nanostructures and more closely resembles chemistry or biology).

In order to examine the structures and composition of the precipitate phases, transition electron microscopy (TEM) and atom probe field ion microscopy (APFIM) are typically used.
TEM provides the morphology, crystal structure and the orientation relationship of precipitates, whilst APFIM gives information on solute clustering and phase chemistry [3].

The TiO2 diffractogram (∆ symbol) presents the most intense peak at 2θ = 25.55° assigned to the (101) plane, characteristic of the anatase phase with tetragonal crystalline structure of TiO2 [JCPDS card 84– 1285].
Each spot in the zig-zag pattern corresponds to a single column of atoms in these materials, allowing the structure to be exactly determined.

Natural zeolites are materials which, due to the peculiarities of their crystal structure and high adsorption and ion exchange properties, have wide prospects for use in technologies of adsorption purification of aquatic environments.
Among the large number of natural sorbents, natural zeolites attract considerable attention due to the peculiarities of their crystal structure and high adsorption and ion exchange properties [7].

Adsorption is a kind of physical chemistry phenomenon and has the great ability to make adsorbent adsorb adsorbate through the effects of molecular van der Waals force, electrostatic force, hydrogen bonding and chemical bonds. between the adsorbent and adsorbate [1].
Catalyst carrier have the following several effects: (1) to increase effective surface area and provide appropriate pore structure; (2)to improve mechanical strength of catalyst, including abrasion resistance, hardness, compressive strength and excellent resistance to impact, etc; (3)to improve the thermal stability of catalyst; (4) to provide the activity center catalysis reaction; (5)to form new compounds with active components; (6)to increase the toxicity resistance of catalyst and reduce the sensitivity to the poison; (7) to save the active components dosage and reduce the cost [2].

Synthesis and Characterization of Tri-n-octylamine- intercalated α-zirconium Phosphate Ruoyu Chen a ,Wei Yao b, Hongning Wang c, Jianwu Wang d Jing Zhonge School of Chemistry and Chemical Engineering, Changzhou University, Changzhou, 213164, China achry@cczu.edu.cn,byaowei85@yeah.net, chnwang@jpu.edu.cn, dwangjianwu0017@163.com,ezjwyz@cczu.edu.cn Keywords: α-zirconium phosphate, Tri-n-octylamine, (C4H9)4NOH, Intercalation composite.
Introduction Α-zirconium bis (monohydrogenphosphate) monohydrate, α-Zr(HPO4)2×H2O (abbreviated as α-ZrP), is known as an inorganic ion exchanger with a layered structure [1].
However, TOA has a large molecular space with dendritic structure, so it is too difficult for TOA to be directly intercalated into the galleries of α-ZrP due to its limited spacing.
But excessive (C4H9)4NOH would destroy the layered structure ofα-ZrP and it was unfavorable to the further intercalation of TOA.
