Description
Technical field
The present invention relates to a kind of catalysis adjuvant, particularly relate to the preparation method of a kind of C nano material.
Background technology
C nano material turns because of the attribute of its uniqueness, Photoinduced Electron as big in two photon absorption cross section, that toxicity is low, good
Shifting ability, causes scientists and studies interest greatly, and C nano material is similar to the hexa-atomic looped network of carbon of graphite and a large amount of non-bonding
Electronics, optional absorption and activate the molecule of some relatively inert.
C nano particle surface has abundant oxy radical, it is easy to surface is modified.It is generally acknowledged the size of carbon nano-particles
The least, its surface area is the biggest, and the biggest light receiving surface of specific surface area is the biggest, and the electron hole pair of formation is the most, shows as light
The while that catalytic efficiency being the highest, specific surface area size is the key factor of reflection substrate adsorbance, and light-catalyzed reaction occurs at catalyst
Surface, target contaminant is attracted to the premise that its surface is photocatalytic degradation.The big then adsorbance of specific surface area is big, and catalysis is lived
Property high.But catalyst such as TiO sometimes2Deng similar hypotoxicity, abundant reserves and good light resistance environment-friendly catalyst
Often there is more Carrier recombination center and little to the absorption region of visible ray so that cause catalysis activity and reduce and meeting
Leading its range of application to be restricted, C nano is to realize effective hands that catalyst is visible light-responded as cocatalyst doping
Section, particularly C nano material, it is possible to promote TiO2The photocatalytic activity of/C composite.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of C nano material, it is possible to promote TiO2/ C composite
Photocatalytic activity.
The present invention is achieved in that taking glucose puts in beaker, is added thereto to sodium hydroxide and then adds
Ionized water stirs 10 min, and wherein glucose and sodium hydroxide mass ratio are 5:1-10:1, sodium hydroxide and deionized water volume
Ratio is 1:150-2:150, in the pyroreaction still of the politef that the mixed liquor of beaker is put into 50 mL, puts in baking oven
160 DEG C, react 4 h, the membrane filtration that reactant liquor uses aperture to be 0.22 μm, remove the insoluble bulky grain in reaction.
The solution have the advantages that: the simple method of the present invention has been prepared and can be used for doping to improve photocatalyst
The C nano material of catalytic performance, it is possible to promote TiO2The photocatalytic activity of/C composite, learns glucose by particle diameter test
Measure that the fewest to record particle diameter the least, and concentration is compared in the material particle size distribution prepared.
