For reaching above-mentioned purpose, the technical solution used in the present invention is:
A kind of self assembly near-spherical Sm2O3The preparation method of/CuO nano-complex, comprises the following steps:
1) first, by analytical pure SmCl3·6H2It is 0.5～2mol/L solution A that O is dissolved in solvent prepared concentration under magnetic stirring；By CuCl2·2H2O dissolves under magnetic stirring and forms the solution B that concentration is 0.5～2mol/L in solvent；
2) secondly, by two parts of solution of A, B according to 1:(0.5～2) volume ratio mix and regulate pH to the 5～8 formation reaction precursor liquid of mixed solution；
3) then, pouring in water heating kettle by reaction precursor liquid, compactedness is 55%～75%, puts in microwave hydrothermal reaction after envelope still, reacts 0.5～2h at 100～200 DEG C, and reaction naturally cools to room temperature after terminating；
4) last, product is washed, calcines, obtain self assembly near-spherical Sm2O3/ CuO nano-complex.
Step 1) in the solvent of solution A and solution B be deionized water.
Step 2) in use mass percent be 5%～10% ammonia spirit regulation mixed solution pH value.
Step 4) described in wash, calcine particularly as follows: successively with distilled water and dehydrated alcohol centrifuge washing 4～be placed on Muffle furnace for 6 times and calcine 2～5h at 500～800 DEG C.
The model of microwave hydrothermal reaction is MDS-10 type.
Relative to prior art, the method have the advantages that
React in the liquid phase due to the present invention and prepare self assembly near-spherical Sm through Technology for Heating Processing2O3The nano combined powder of/CuO, process equipment is simple, low cost, and manufacturing cycle is shorter, and Product size is uniform, good dispersion.
The present invention prepares a kind of self assembly near-spherical Sm2O3/ CuO nano-complex, reaction medium is aqueous solution, and safety is high, and reaction raw materials is easy to get, and feasibility is strong, and process equipment is simple.The stirring utilizing microwave can realize on molecular level as heating tool, has firing rate fast, homogeneous heating, without thermograde, without hysteresis effect, Product size is evenly distributed, good dispersion, and the product purity prepared through Technology for Heating Processing again after microwave hydrothermal is high, good crystallinity.
Sm2O3As a kind of wide bandgap semiconductor, in terms of light degradation Organic substance, there is preferable Research Prospects, but because of forbidden band wider (Eg=4.4eV), relatively low to the responsiveness of visible spectrum.But the recombination probability of its photo-generate electron-hole pair is greatly reduced, can carry out compound with the part that compensates its defect with low-gap semiconductor.As low-gap semiconductor, at the bottom of the conduction band of CuO, compare H+/H2Just, energy gap is 1.7eV to oxidation-reduction potential, and the response to visible spectrum is stronger.After both are combined by the present invention, CuO can effectively absorb visible ray as light-absorption layer so that photo-generate electron-hole is to efficiently separating, and protects CuO not by photoetch, thus improves photocatalysis efficiency.
