Description
Technical field
The present invention relates to nickel manganese double-metal hydroxide technical field, more particularly to a kind of nickel manganese double-metal hydroxide,
Photochemical catalyst and electrode material.
Background technology
Layered double-hydroxide (layered Double Hydroxide, abbreviation LDHs) is also known as Layered compound or class water
Talc compound, (Hydrotalcite, molecular formula is Mg to the neatly stone ore that its crystal structure exists with nature6Al2(OH)16CO3 4H2O) structure is similar.Lasting is studied to it since layered double-hydroxide self-discovery, it is in catalytic chemistry, ion
The aspects such as exchanger, adsorbent, electrochemistry, photochemistry, are widely used.Layered double-hydroxide contains abundant lamella,
Can be used as the electrode material of ultracapacitor, it can simultaneously utilize two kinds of energy storage mechnisms of electric double layer capacitance and pseudo capacitance,
On the one hand by provide bigger serface improve electric double layer capacitance, on the other hand using transition metal on laminate oxidation also
Original reaction provides pseudo capacitance higher.And, the unique space structure of layered double hydroxide makes it have alkali
Property, interlayer anion interchangeability, heat endurance.Due to these characteristics, layered double hydroxide is increasingly becoming more satisfactory
Electrode material for super capacitor.
Meanwhile, LDHs is also rising as the research of photochemical catalyst, because the laminate ion of layered double-hydroxide has
There is substitutability, by such as Zn of the ion with photocatalytic activity2+Or Ti2+Metal cation in being constituted as LDHs, can make
The standby material with photocatalytic activity.
The current double-hydroxide species for preparing is rich and varied, including NiMn-LDH, NiAl-LDH, CoMn-LDH, CoAl-
LDH, NiCo-LDH etc..NiMn-LDH can make full use of two kinds of cooperative effects of metal in these double-hydroxides, can
Ensure more abundant, quick ionic adsorption with desorption and cyclical stability.But nickel manganese double hydroxide nano piece is in circulation
During structure swelling and the caused capacity attenuation that caves in limit its further development in practice, therefore improve
The chemical property of nickel manganese double-hydroxide turns into the focus of people's research.
The content of the invention
In view of this, it is an object of the invention to provide a kind of nickel manganese double-metal hydroxide composite, the present invention is carried
The nickel manganese double-metal hydroxide composite of confession has preferable chemical property and photocatalysis performance simultaneously.
The invention provides a kind of nickel manganese double-metal hydroxide composite, including：
Bismuthyl carbonate；
It is supported on the nickel manganese double-metal hydroxide on the bismuthyl carbonate surface.
Preferably, the nickel manganese double-metal hydroxide is：
Ni1-xMnx(OH)2·mH2O
Wherein, 0 ＜ x ＜ 1, m are 1~10.
Preferably, the mass ratio of the bismuthyl carbonate and nickel manganese double-metal hydroxide is (1~4)：(1~2).
The invention provides a kind of preparation side of the nickel manganese double-metal hydroxide composite described in above-mentioned technical proposal
Method, including：
Bismuthyl carbonate and alkaline matter is soluble in water, obtain dispersion liquid；
The dispersion liquid, nickel salt and manganese salt are reacted, nickel manganese double-metal hydroxide composite is obtained.
Preferably, the alkaline matter is selected from NH4NO3、C6H12N4、C6H5Na3O7, Na (OH), in K (OH) and urea one
Plant or several.
Preferably, the nickel salt is selected from one or more in nickel nitrate, nickel sulfate, nickelous carbonate and nickel chloride.
Preferably, the manganese salt is selected from one or more in manganese nitrate, manganese sulfate, manganese carbonate and manganese chloride.
Preferably, the temperature of the reaction is 70~100 DEG C.
The invention provides a kind of photochemical catalyst, including nickel manganese double-metal hydroxide described in above-mentioned technical proposal is combined
Material.
The invention provides a kind of electrode material, including nickel manganese double-metal hydroxide described in above-mentioned technical proposal is combined
Material.
Compared with prior art, the nickel manganese double-metal hydroxide composite of present invention offer is to carry with bismuthyl carbonate
Body, bismuthyl carbonate area load has nickel manganese double-metal hydroxide, and bismuthyl carbonate grows as nickel manganese double-metal hydroxide
Matrix, can guide and control its appearance structure；And bismuthyl carbonate can with the tight connection of nickel manganese double-metal hydroxide
More fully, quickly for redox reaction provides ion channel；Make jointly in nickel manganese double-metal hydroxide and bismuthyl carbonate
Under, the composite for enabling to is while have preferable chemical property and photocatalysis performance.
In the present invention, above-mentioned nickel manganese double-metal hydroxide composite structure stabilization, size are controllable, chemical property
Superior, with specific capacitance and energy density higher, and electrochemical cycle stability is preferably, after circulation, composite structure
Keep complete.Meanwhile, this nickel manganese double-metal hydroxide composite also has good photocatalysis performance.Therefore, this hair
The nickel manganese double-metal hydroxide composite of bright offer can be used as electrode material and photocatalyst applications.
