Specific implementation mode
Presently in connection with specific embodiment, the invention will be further described, following embodiment be intended to illustrate invention rather than
Limitation of the invention further.
Embodiment 1
(1) bacteria cellulose is handled:Bacteria cellulose aquagel by Guilin Qi Hong Science and Technology Ltd.s provide, and to its into
Row reprocessing.Bacteria cellulose aquagel is purified in NaOH aqueous solutions, removes the bacterium in striping and Residual reactants, then
It is washed to pH=7.0 using deionized water.Bacteria cellulose after washing is cut into small pieces and is immersed into liquid nitrogen, it is dry to carry out freezing
It is dry, obtain the bacteria cellulose aeroge with layered structure.;
(2) preparation of CdS nanometer sheets:0.1M sodium citrates, certain density CdCl are added in the ethanol solution of 100ml2,
It is put into 50mg bacteria celluloses.Ultrasonic 10min makes cadmium salt uniform settlement on cellulose, and it is dense that 0.7ml is then added into solution
Ammonium hydroxide, 0.2M thiocarbamides.Solution is sealed in autoclave, and is heated in an oven, obtained sample with ethanol cleans several times, clearly
