Anisotropy it is nanocrystalline, general its a diameter of 1-200 nm, length is tens microns.Nano wire is spherical nanocrystalline because of shape with its
Looks difference causes the characteristics such as physical property to have larger difference.1D nano structural materials research application in a major issue be as
What effectively prepares 1D nanostructureds by controllable method.Although senior nanometer lithographic techniques, such as electron beam lithography, nearly probe
The technology such as modification and X-ray lithographic can prepare 1D nano structural materials, but these method preparation process are slow and cost is very high,
Cannot be promoted in actual applications.Therefore, at present research focus mostly in by chemical method prepare 1D nano structural materials,
Because such method can realize the control to nanometer dimension, while cost is relatively low, yield is higher.
In numerous 1D nano structural materials, metal nanometer line increasingly causes extensive concern.From German Gleiter in
Since 1984 Fe nanometer particles for preparing 6 nm first, in the world to the research mushroom development of nano metal, and achieve very
Big progress.Wherein, copper nano material increasingly causes the concern of researcher.Silver halide is widely used in manufacturing photo film, glue
Silver chlorates also have very important application in electrochemistry in version and gummed paper, and silver-colored monochlor(in)ate silver reference electrode is difficult polarization, thus
The photosensitivity of more accurate data silver halides can be provided and its application in terms of photocatalysis is instability limit, such as
Fruit can make silver halide stable existence can just be applied to photocatalysis aspect under light illumination and the argent of nanoscale exists
There is stronger absorption in black light area, and by adjusting the size of argent, the environment residing for shape and nano particle can make
There is red shift in its absorption spectrum.In theory, it is possible to use silver nano-grain strengthens absorption of the catalysis material to sunshine.This
Copper is effectively combined with silver chlorate in experiment, the network structure of Cu/AgCl is formed, firstly, since metallic copper and chlorination
The close contact of silver, makes electronic energy produced in system be easier to be delivered in metallic silver particles, has been effectively promoted electronics
Separation with hole and then improve quantum efficiency, it is ensured that the stability of system;Secondly, this novel network structure have compared with
Big specific surface area, can provide more light-catalysed avtive spots, improve catalytic efficiency;Again, the nano-cable knot of Cu@AgCl
Structure has effectively expanded response of the system to visible ray, it is had very strong absorption in whole visible region, substantially increases
To the utilization rate of sunshine.This method has been widened can by metal surface plasmon resonance effect reinforcement catalysis material pair
See the approach of light absorbs, and then improve the performance of catalysis material.
