Embodiment 1
[0026] 1) Weigh 2mmol of cadmium chloride and 4mmol of sodium diethyldithiocarbamate into a 100mL beaker, add 50mL of deionized water, and stir at a speed of 500r / min for 60min to obtain a suspension A.
[0027] 2) The suspension A was separated by centrifugation at a centrifugal speed of 7000r / min, and the separated solid matter was dried in an oven at 60°C to obtain the precursor B.
[0028] 3) Take 1.124g of precursor B, add 40mL of ethylenediamine, stir at a speed of 400r / min for 60min to form a uniform and stable solution, transfer to a 50mL hydrothermal reaction kettle, keep at 180°C for 24h, cool to room temperature, and obtain a suspension Turbid liquid C.
[0029] 4) Separating the cadmium sulfide in the suspension C by suction filtration, washing with water and alcohol for several times, drying the separated solid matter in an oven at 60° C. to obtain cadmium sulfide nanowires.
[0030] 5) Weigh 100 mg of cadmium sulfide nanowires, add 40 ml of deionized water, and ...
