Preparation of Cu2O (Cu)/MWCNTs composite particles and their gas sensor properties ZHANG ZhuanFang1,a, YIN GuangMing1,b, Yang Ying2,c 1Analysis and testing centre, Qiqihar University, Qiqihar, 161006, China 2School of Chemistry and Chemistry Engineering, Qiqihar University, Qiqihar 161000, China azhzhf1234@163.com, bqdyingm@163.com, cyangying0807@126.com Keywords: Cu2O (Cu)/MWCNTs, NOx, gas sensing.
But because of their own chemical properties and structure of CNTs, CNTs for NOx gas sensitivity is still low.
According to the standard card, the diffraction peaks at 26° and 43° correspond to the graphitic structure of the CNTs.
These factors are closely related to the structure of the sensor material [13].
Conclusions In this work, the Cu2O(Cu)/MWCNTs composites show unique structure and exhibit excellent sensing properties with not only high sensitivity but also fast response at room temperature to NOx detection When the concentration of NOx is 700 ppm, the sensitivity and response time are about 20.3 % and 13 s respectively.

The enormous effort to understand the physics involved even in tiny structures follow parallel attempts to exploit to potential beneficial properties.
However, as a handicap, the increased surface area and tailored surface chemistry of metal nanoparticles have long been used to optimize the activity and specificity catalytic uses [2].
This behavior was already proposed for other layered structures after metallic nanoparticles deposition [15].
The diagonal spot disposition and distances among them, is in authentic agreement with (111) orientation for fcc silver crystal structure.

In addition, porous carbons [20-23] (Activated Carbon, Carbon Nanotubes, Graphene, etc.) have their advantages of unique pore structure, high electrical conductivity and high specific surface area.
The structure and morphology of samples were characterized by XRD and SEM.
Rather, their diffraction peaks are much sharper, especially TNRGO/MnO2 sharpest, which indicates all two-component catalysts have perfect structure and high purity.
Secondly, compared with them also have sharper peaks, more perfect structure and higher purity.

Intense research activity started in the late 1980s after the development of the multilayered cell structure by Tang and Vanslyke[2], it can keep the hole and electron limited in the interface between the Hole-transport Layer and Electron-transport Layer, then carrier recombinated and exciton formated.
Actually, we can get the difference contract between the molecular structure.
TM 2 have much larger area of conjugate band, better rigidity plane structure, so that the delocalized electron can be excitated much easy, and fluorescent light could be emission with ease.

It was impossible to completely graphitize in such a low-temperature system, so the macroscopy of the samples show amorphous structure.
Fig. 6 shows a broad peak centered at 2θ angle of 22o, which is typical amorphous solids, and confirms the absence of any ordered crystalline structure.

Crystal structure of LaBa2Cu3S6-y was orthorhombic and refined unit cell parameters were a =10.16(1), b=12.72(2) and c=13.54(0)Å.
The structure and bonding of most binary metal sulfides differs significantly from those of corresponding metal oxides.
Replacement of Cu by Fe also gave a material having similar orthorhombic structure with a semiconductivity.
It is isostructural with Pr2SrS4 which has Th3P4 structure.

Introduction In the ternary Al-Mg-B system, two types of ternary structures, namely AlMgB14 (orthorhombic, space group Imam) and AlMgB22 (orthorhombic, space group P212121) have been reported so far [1, 2].
The crystal structures and unit-cell parameters of the compounds were examined by the X-ray diffraction (XRD).
As seen from Table 1, four types of structures, namely AlB2, � -AlB12, AlMgB14 and AlMgB22 were identified, while crystals of � -AlB12 and MgB2 were not detected by XRD.
This anisotropic nature of hardness seems to be related to the difference in the number of B12 icosahedral units and B-B bonds for linkage of boron atoms in the structures.
