Description
Technical field:
The present invention relates to cuprous oxide field of material technology, specifically a kind of supported porous oxidation of nano porous copper is sub-
Copper nanosheet composite material and preparation method thereof.
Background technique:
Cuprous oxide is a kind of p-type narrow band gap (2.17eV) semiconductor material, active electron-hole pair system, because
This shows good catalytic activity, in terms of show very big application potential.Many institutes
Known, the degradation property of catalyst is often depending on its effective surface area and porosity.Therefore nanosizing and porous, are to mention
The effective ways of high cuprous Photocatalytic Degradation Property.
First technology, publication number CN102965711B " the anodic oxidation two-step method of cuprous nano flaky powder material
Preparation method " is that substrate in copper foil surface grows cuprous oxide nano-sheet powder using copper foil in the patent.Due to copper foil base
Copy for the record or for reproduction body reduces the adequacy of reaction without porous structure, increases the transmission range of reaction solution and internal nanometer sheet.This
Outside, the cuprous nano piece average diameter of preparation is larger, it is easy to fall off from matrix, the machinery for affecting the composite material is complete
Whole property.
First technology, publication number CN106229462A " the three-D nano-porous cuprous nano-chip arrays type lithium of copper/two dimensional oxidation
Ion battery cathode and one one-step preparation method ", in the patent, need by cuprous nano piece obtained under vacuum conditions into
Row is dry to avoid being oxidized, and illustrates unstable using cuprous nano piece made from this method.In addition it is made under vacuum condition
Standby cuprous nano piece increases experimental cost, is unfavorable for marketing.
Summary of the invention:
It is an object of the present invention to easily reunite in use for cuprous nano piece in current techniques, use
Later the deficiencies of being not easily recycled and being easily oxidized provides a kind of supported porous cuprous nano piece composite wood of nano porous copper
Material and preparation method thereof.The material includes noncrystal substrate nano porous copper composite bar and the porous oxidation for being supported on its surface
Cuprous nanometer sheet.Preparation method is first to be heat-treated amorphous bar, removes the residual stress inside amorphous bar.Then
A kind of supported porous cuprous nano piece composite material of nano porous copper is made using de- alloying technology and anode oxidation process
(wherein 80~140 μm of nano porous copper thickness, tough 110~140nm of bandwidth, 40~100nm of aperture size；Nanometer sheet thickness 50
~90nm, nanometer length of a film 30~80nm, wide 5~10nm.It distributed the nano aperture of a large amount of 1~4nm scale in nanometer sheet).
Rodlike composite material prepared by the present invention has bigger specific surface area and more active sites compared to reported at present
Point, and nanometer sheet is not easily to fall off.Use easily recycling later, is recycled recycling.The composite material has in photocatalytic degradation
Machine dye field occupies unique structure and performance advantage.
The technical scheme is that
A kind of supported porous cuprous nano piece composite material of nano porous copper, the composite material are bar, including non-
Brilliant matrix, the nano porous copper being covered on noncrystal substrate and the cuprous nanometer of porous oxidation for being supported on nano porous copper surface
Piece；The noncrystal substrate is CuxZryTizAlwAlloying component, wherein x, y, z, w are atomic percent, 45≤x≤50,20≤
Y≤25,25≤z≤30,5≤w≤10 and x+y+z+w=100；Wherein 80~140 μm of nano porous copper thickness, tough bandwidth 110
~140nm, 40~100nm of aperture size；Nanometer sheet 50~90nm of thickness, nanometer length of a film 30~80nm, wide 5~10nm, nanometer
The nano aperture of on piece is having a size of 1~4nm.
The preparation method of the supported porous cuprous nano piece composite material of the nano porous copper, including walk as follows
It is rapid:
The first step prepares amorphous alloy bar
According to target ingredient weighs pure Cu, pure Zr, pure Ti and pure Al；Melting in vacuum arc melting furnace is put into after cleaning to be made
Cu-Zr-Ti-Al alloy pig, polishing, cleaning are placed in quartz test tube, and quartz test tube is put into vacuum and gets rid of the line of induction in band machine
It is fixed in circle, induction melting is carried out under high-purity argon gas protection, molten metal liquid is blown into copper mold, forms its solidification non-
Peritectic alloy bar；Wherein: melting and get rid of band vacuum degree be 9 × 10-4Pa；Blowing casting pressure is 0.5~2.0MPa；Copper mold bore dia is
1~3mm；Amorphous alloy coupon diameter obtained is 0.9~2.9mm of Ф, and length is 30~70mm；
Amorphous alloy bar is heat-treated by second step
Amorphous alloy bar obtained in the previous step is placed in tube furnace, in the case where logical argon gas, with 2~4 DEG C of min-1
Speed from 25 DEG C of temperature programmings to 150 DEG C, after constant temperature keeps 1~3h, then with 10 DEG C of min-1Speed program be warming up to 200
