In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.
Example 1:
respectively dissolving 1g, 2g and 3g of urea in deionized water, adding 0.0314g of silver nitrate into the solution under magnetic stirring, stirring for 1h, adding 2g of active carbon, stirring overnight, evaporating water, drying in an oven, and calcining at 550 ℃ under nitrogen protection to obtain nano-particlesCarbon material Ag-CNx/AC(1:2)、Ag-CNx/AC(2:2)、Ag-CNx/AC(3:2)。
Example 2:
dissolving 0.0314g of silver nitrate in deionized water, adding 2g of activated carbon, stirring overnight, evaporating water, drying in an oven, and calcining at 550 ℃ under the protection of nitrogen to obtain the nano carbon material Ag/AC.
Example 3:
dissolving 1g of urea in deionized water, adding 2g of activated carbon under magnetic stirring, stirring overnight, evaporating water, drying in an oven, and calcining at 550 ℃ under the protection of nitrogen to obtain a carbon material CNx/AC。
Example 4:
a multifunctional nano carbon material treated rhodamine B for drinking water purification comprises the following steps:
weighing 50mg of the nano-carbon material prepared in the examples 1-3, adding the nano-carbon material into 100mL of rhodamine B wastewater with the initial concentration of 20 mg/L under the condition of keeping out of the sun, stirring for 2h, carrying out photocatalytic reaction for 3h by using a 300W xenon lamp with a 420nm ultraviolet cut-off filter as a light source after adsorption and desorption balance is achieved, and finishing treatment on the rhodamine B wastewater.
FIG. 1 is a time-reaction efficiency curve diagram of the adsorption and photocatalytic degradation of rhodamine B by the nanocarbon materials obtained in examples 1 to 3 of the present invention. As shown, the degradation rate gradually increased with the increase of the reaction time. Nano carbon material Ag-CNxThe best degradation effect is achieved when the mass ratio of urea to active carbon in the/AC is 2: 2. Low content of CNxThe absorption of visible light and thus the photocatalytic effect is affected. And with CNxThe content increases, and the pores of the AC may be blocked, resulting in a decrease in specific surface area, and thus a decrease in efficiency. Example 2 the Ag/AC effect was not as good as Ag-CNx[ AC (2:2) ] CN obtained in example 3xThe Ag/AC and CN are not as good as the material loaded with silver in degradation effectxWhen the/AC is mixed together, although the adsorption action is strengthened, the increasing range of the degradation rate is reduced in the degradation process.

dissolving 2g of urea in deionized water, adding 0.0314g of silver nitrate into the solution under magnetic stirring, stirring for 1h, respectively adding 2g of sawdust activated carbon, shell activated carbon and coconut shell activated carbon, stirring overnight, then evaporating water, drying in an oven, calcining at 550 ℃ under the protection of nitrogen, and respectively obtaining carbon materials of 3 different carriers, wherein according to the method for treating rhodamine B in example 4, the degradation rates of the three carbon materials are respectively 70.5%, 71.9% and 72.2%, so that the influence of the type of the activated carbon on the material performance is small.
Example 6:
in order to investigate the influence of a carbon nitride precursor on the material performance, the effect of degrading rhodamine B by using a carbon material prepared by using urea, melamine and dicyandiamide as a carbon nitride precursor is respectively researched:
adding 2g of urea, melamine and dicyandiamide into a solvent, adding 0.0314g of silver nitrate into the solution under magnetic stirring, stirring for 1h, adding 2g of activated carbon, stirring overnight, evaporating water, drying in an oven, calcining at 550 ℃ under the protection of nitrogen to obtain carbon materials of 3 different precursors, wherein the degradation rates of the three carbon materials are 72.2%, 61.1% and 57.7% respectively according to the method for treating rhodamine B in example 4. Therefore, the carbon material prepared by using urea as a precursor has the best effect probably because the specific surface area of carbon nitride prepared by using urea is larger.

FIG. 2 is a time-reaction efficiency curve diagram of the adsorption and photo-reduction of hexavalent chromium by the nanocarbon materials obtained in examples 1 to 3 of the present invention. As shown in the figure, the reaction efficiency gradually increased with the increase of the reaction time. The reaction result is consistent with that of rhodamine B, and the nano carbon material Ag-CNxThe best effect is achieved when the mass ratio of urea to activated carbon in the/AC is 2: 2. As can be seen from fig. 2, the adsorption effect in the first stage is strong. Therefore, to further study the adsorption behavior, pseudo-primary and pseudo-secondary models were used to fit the adsorption kinetics data.
As can be seen from the following table, the correlation coefficient of the quasi-secondary kinetics of the adsorption of the hexavalent chromium by the nano-carbon material is higher than that of the quasi-primary kinetics, and the theoretical equilibrium adsorption capacity (q) calculated from the theoretical resulte,cal) And experimental data (q)e,exp) Approximately the same, the adsorption of the nano carbon material to hexavalent chromium follows quasi-second-order kinetics, the main control step of the adsorption rate is a chemical adsorption process, and a large number of active adsorption sites exist on the surface of the nano carbon material.

FIG. 3 shows the nanocarbon materials Ag-CN obtained in examples 1 to 3 of the present inventionx/AC(2:2)、Ag/AC、CNxTime-kill curve for/AC. As shown in the figure, the nano carbon material Ag-CNXThe antibacterial effect of the/AC (2:2) is the best, the sterilization rate reaches 99.98 percent within 3 hours, and the sterilization rate of the Ag/AC and the CNX/AThe sterilization rate of C is 97.87 percent and 99.82 percent respectively. The result shows that Ag not only improves the photocatalytic activity, but also improves the antibacterial efficiency due to the existence of the nano silver.
