Description
Technical field
The present invention relates to new forms of energy technical field of nanometer material preparation, be specifically related to the method for the Cu-Al reasonable offer nano porous copper of a kind of micro-Ni doped/Ti.
Background technology
In recent years, the rise and development of nanosecond science and technology and nano material makes a class novel metal nano structural material-nano porous metal (hole wall is in nanoscale, and 1 to 100nm) receive increasing concern.Because nano porous metal has even porous structure, so there is the key property such as high-specific surface area, low density, nano porous metal material is applied on a large scale at material neighborhood.
Nano porous metal material can be prepared by different alloy systems.Calendar year 2001, J.Erlebacher, by corrosion Au-Ag reasonable offer nano-porous gold, makes de-alloy (dealloying) legal system obtain extensive concern for metal nano vesicular structure.Subsequently, all occur that lot of documents report is as the preparation of the noble metal nano porous materials such as Au, Ag, Pd, Pt both at home and abroad.These nano-porous materials all kinds of high efficient energy sources store and switch technology as fields such as lithium ion battery, ultracapacitor, Proton Exchange Membrane Fuel Cellss in obtain and study application widely.But higher production cost limits nanoporous precious metal industrial application widely.
Compared with nanoporous precious metal, nano porous copper is a kind of very attractive, cheap nano-porous materials.So far, the correlative study of nano porous copper is mainly passed through Zn-Cu, Mn-Cu, the Binary Alloy Systems such as Zr-Cu, Mg-Cu carry out de-alloy treatment and prepare nano porous copper, but these methods have some shortcoming following: 1. matrix alloy preparation is complicated, 2. price is higher, 3. the pore size of the nano porous copper prepared is uneven, and then causes its chemical property not good, cannot produce a desired effect.
For arriving desired result, carried out various modification experiment to nanoporous copper product, although there is certain effect of optimization, its modified technique is complicated, and cost is higher and be difficult to widespread use.Under the development trend of nanoporous copper product high electrochemical performance, simple preparation technology, low cost, market active demand one has electrochemical performance, preparation technology's simple low cost nanoporous copper product.How to realize premised on high electrochemical performance, obtain that technique is simple, low cost can the nanoporous copper product of widespread use be problem demanding prompt solution in current nano porous copper investigation of materials.
At present, the achievement in research of nanoporous copper product is as follows:
Hebei University of Technology, in CN103343253B patent, discloses a kind of method preparing nano porous copper, and it is simple that this material has technique, the feature that cost is low.But, the starting material that this patent adopts are amorphous ribbon, prepare amorphous ribbon, just require that corresponding mother alloy system has very high amorphous formation ability, this point compare and alloy strip, to original mother alloy choose and follow-up fusing quick-quenching prepare alloy thin band preparation technology require higher.
Xi'an Communications University is in CN104624200A patent, and disclose a kind of preparation method of nanoporous cupric oxide loaded metal catalytic material, the method prepares nanoporous cupric oxide loaded nano-precious metal particles, has good catalytic oxidation performance advantage.But the method for modifying of this patent to nano porous copper is after carrying out de-alloy to the X alloy strip containing precious metal, be placed in the air roasting 1 ~ 3 hour of 300 ~ 900 DEG C.In virgin alloy preparation process, add a small amount of precious metal add preparation cost to a certain extent, and precious metal also has a certain amount of loss in follow-up de-alloy process.High-temperature roasting modifying process subsequently requires higher to processing condition, is unfavorable for practical application.
Above-mentioned patent optimizes modified Nano Porous Cu material by different methods, but still there are following two remarkable shortcomings: the preparation of (1) starting materials requires higher (amorphous ribbon), processing condition are harsh, this greatly limits its application industrially; (2) modification technology complexity (high-temperature roasting) and introduce other subsidiary material (precious metal interpolation) to some extent, improves preparation cost.
To sum up, lack preparation technology and modification technology in the market simple, production cost is low, possesses electrochemical performance nanoporous copper product simultaneously.Therefore, develop a kind of by simple preparation technology and modification technology method obtain high electrochemical performance, lower production cost, widespread use the investigation and application of nanoporous copper product to current nanometer perforated electrodes material there is meaning of crucial importance.
