Description
Technical field
The present invention relates to the method for a kind of deposition-dipping synthesis of nano-zinc oxide/bamboo charcoal catalysis material.
Background technology
Bamboo charcoal has flourishing pore structure, and wide material sources, and is cheap; As a kind of novel absorption material, aspect environmental protection, be widely used as surrounding purifying material with pernicious gas such as formaldehyde in the absorbed air with as material for water treatment; But; Bamboo charcoal absorption pollutant does not destroy pollutant to remove toxin, and this makes the adsorption capacity of bamboo charcoal reduce gradually along with the prolongation of service time, and inevitably will produce secondary pollution.Therefore, bamboo charcoal being carried out modification makes it existing better absorption property and has regenerability to have great importance again.Nano zine oxide is the good photochemical catalyst of a kind of photocatalysis performance, but there is the problem that reclaims difficulty during as photochemical catalyst in the powder nano zine oxide.With nano zine oxide and the organic contamination of load composite degradation, not only can bring into play the catalytic performance of nano zine oxide, also can improve it catalytic efficiency and change the shortcoming that is difficult to recycling when zinc oxide is single to be used.And bamboo charcoal is as a kind of functional novel environment friendly material; The strong adsorptivity of itself has certain function to the aspect such as purifying, antibacterial; Utilize the bamboo charcoal adsorption capacity to prepare the composite of bamboo charcoal and nano zine oxide; The adsorptivity that realizes bamboo charcoal effectively combines with the nano-ZnO property, is used for useless dirty the processing, is expected to become the hot issue of people's research.
Summary of the invention
The object of the invention provides the method for a kind of deposition-dipping synthesis of nano-zinc oxide/bamboo charcoal catalysis material; Be the adsorptivity of comprehensive utilization bamboo charcoal and the photocatalysis of nano zine oxide; Nano zine oxide is carried on the bamboo charcoal, makes both advantages obtain perfect adaptation.
It is raw material that the present invention adopts NaOH, Zinc vitriol; Polyethylene glycol-6000 is done dispersant; Adopt the method for deposition-dipping under the certain reaction temperature and time, to prepare nano zine oxide-bamboo charcoal composite; And be to handle the organic matter research object with the methylene blue, estimate the absorption and the photocatalysis of this composite and fall performance.
Concrete steps are:
(1) the Macrogol 6000 adding with 0.1-0.25g fills in the beaker of 30mL distilled water, and stirring and dissolving evenly back adds ZnSO
47H
2O 0.0043-0.086g, and make its uniform dissolution;
. (2) add the 0.5-1.0g bamboo charcoal in step (1) gained solution, at the uniform velocity stir 4h under the room temperature; Then slowly drip the NaOH solution 20mL of 0.0015mol/L, dropwise under the room temperature of back and continue at the uniform velocity to stir 8h;
(3) step (2) gained mixed solution is transferred in the thermostat water bath under 70-90 ℃, at the uniform velocity stirs at constant temperature and continue reaction 50min down;
(4) take out the beaker room temperature after reaction is accomplished and at the uniform velocity stir down cooling, filtration, washing, oven dry promptly get catalysis material.The ZnO nano particle is spherical in the catalysis material, and average grain diameter is about 40-100nm.
With methylene blue is organic target degradation product, estimates absorption and the photocatalysis performance of nano-ZnO/bamboo charcoal catalysis material under natural daylight, ultraviolet light, dark condition, and compound reaches 77-96% to the percent of decolourization of methylene blue under ultraviolet light.
It is simple, easy to operate that the present invention has a production equipment, control easily, in the compound ZnO particle diameter little, be evenly distributed nano-complex absorption property and photocatalysis performance advantages of higher.
The specific embodiment
Embodiment:
(1) adding of 0.2g Macrogol 6000 is filled in the beaker of 30mL distilled water, stirring and dissolving evenly back adds ZnSO
47H
2O 0.0043g, and make its uniform dissolution;
(2) in step (1) gained solution, add the 0.5g bamboo charcoal, at the uniform velocity stir 4h under the room temperature; Then slowly drip the NaOH solution 20mL of 0.0015mol/L, dropwise under the room temperature of back and continue at the uniform velocity to stir 8h;
(3) step (2) gained solution is transferred in the thermostat water bath under 80 ℃, at the uniform velocity stirs at constant temperature and continue reaction 50min down;
(4) take out the beaker room temperature after reaction is accomplished and at the uniform velocity stir down cooling, filtration, washing, oven dry promptly get catalysis material; The ZnO nano particle is spherical in the catalysis material, and average grain diameter is about 43nm.
This catalysis material percent of decolourization to methylene blue under natural daylight and under the ultraviolet light all improves a lot than bamboo charcoal, and percent of decolourization is the highest under the ultraviolet light, and natural daylight takes second place.1 hour rear decoloring rate of UV-irradiation is that 93%, 4 hour rear decoloring rate is 96%.
