Study on the Preparation of Ag And PbS Doping TiO2 Nanotube Arrays and its Photocatalytic Properties
Anodic oxidation process for producing TiO2 nanotubes, in the rational allocation of the electrolytic solution 3 hours, calcination temperature was gradually heated up to 450 degrees for a total of more than three hours.Na2S and PbCl2 then prepared solution of 100ml stand by TiO2 nanotube alternately number of shocks in the two different solutions so that its surface doping different amounts of PbS, then the prepared five kinds of styles into methyl orange solution the photocatalytic degradation experiments, each time interval of 30 minutes, 5 sets of data measured to calculate the degradation rate one of the highest group, indicating that the concentration decreases in the rate of the best solution, in this sample of methylene blue, rhodamine B in photocatalytic degradation experiment.On the experimental basis and then made the first top five degradation of the sample, prepared NaBH4 solution and AgNO3 solution of 100ml stand, the next step was similar to the front of the shock by alternating different frequency such that different amounts of silver doped sample surface, Similar experiments photocatalytic degradation of methyl orange, methylene blue, rhodamine B, the calculated degradation rate of the highest quintile, this photocatalytic TiO2 nanotube array comparative data in each group that is able to draw a total of Ag and PbS doped Best performance properties.Finally, the two groups prepared PbS doped nanotubes and doped PbS and Ag 2 groups of nanotubes spare inspection
