Detailed description of the preferred embodiment
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Example 1

adding the carbon nano tube treated in the steps into a reaction kettle, and then adding Na2MoO4·2H2O, Se powder, NaBH4 and ethanol water solution, wherein the carbon nano tube and Na2MoO4·2H2O, Se powder and NaBH4The concentrations of (A) were 0.5g/L, 0.14mol/L, 0.49mol/L, and 0.17mol/L, respectively. Wherein the ethanol water solution is 40ml (ethanol: water 1: 1); putting into a vacuum drying oven, and keeping the temperature at 220 ℃ for 24 hours; collecting the precipitate, and treating with NaOH solution at 80 deg.C for 2 hr, wherein the concentration of NaOH solution is 10 mol/L; and finally, carrying out centrifugal cleaning and drying to obtain a sample 1.
Transmission and scanning of the composite of carbon nanotubes and molybdenum diselenide as shown in fig. 1 and 2, fig. 1 can see that there are a small number of carbon nanotubes on the flower-like molybdenum diselenide, which is not easily observable under the low power lens due to the low carbon nanotube content and the small size of the carbon nanotubes in the composite. Under the high power lens in fig. 2, the composite material can be clearly seen to be composed of flower-shaped molybdenum diselenide and carbon nanotubes, and the network-shaped carbon nanotubes and the flower-shaped molybdenum diselenide are effectively combined, so that the visible light absorption in photocatalysis is facilitated, the transmission of electrons is facilitated, and the successful synthesis of the composite material of the carbon nanotubes and the molybdenum diselenide is further verified.
Example 2:

As can be seen from the scanned graph of the composite material (fig. 3) of the carbon nanotube and the molybdenum diselenide, when the content of the carbon nanotube is high, the carbon nanotube is uniformly wrapped on the flower-shaped molybdenum diselenide, and the carbon nanotube covered on the surface of the flower-shaped molybdenum diselenide is more favorable for the transmission of electrons, so that the photocatalytic reaction is more efficiently carried out.

Example 4
Pouring carbon nano tubes and concentrated nitric acid into a reaction kettle, wherein the ratio of the carbon nano tubes to the concentrated nitric acid is 20mg to 100 ml; the hydrothermal temperature is 150 ℃, and the heating time is 1 hour; collecting the precipitate after the reaction is finished, adding an acetone solution, and performing ultrasonic treatment for 30 min; then washing with deionized water and alcohol for 3 times; drying; grinding for later use;
adding the carbon nano tube treated in the steps into a reaction kettle, and then adding Na2MoO4·2H2O, Se powder, NaBH4 and ethanol water solution, wherein the carbon nano tube and Na2MoO4·2H2O, Se powder and NaBH4The concentrations of (A) were 0.5g/L, 0.14mol/L, 0.49mol/L, and 0.17mol/L, respectively. Wherein the ethanol water solution is 40ml (ethanol: water 1: 1); putting the mixture into a vacuum drying oven, and keeping the temperature at 240 ℃ for 24 hours; collecting the precipitate, and treating with NaOH solution at 80 deg.C for 2 hr, wherein the concentration of NaOH solution is 10 mol/L; and finally, carrying out centrifugal cleaning and drying to obtain a sample 4.

With pure silver phosphate as a control.
As can be seen from fig. 4, when the LED lamp was turned on, the photocatalytic oxygen generation rate rapidly increased due to the higher oxygen generation activity of the silver phosphate and the flower-like molybdenum diselenide/carbon nanotube composite material in cooperation, and after 10min, the rate of increase was slow and substantially reached a steady state, which also indicates that the silver phosphate and flower-like molybdenum diselenide/carbon nanotube composite material had high stability. And at 45min, the oxygen production rate of the silver phosphate and flower-shaped molybdenum diselenide/carbon nano tube composite material reaches 23 mu mol/L, which is about 3 times of the oxygen production rate of pure silver phosphate, and the high-efficiency oxygen production activity of the silver phosphate and flower-shaped molybdenum diselenide/carbon nano tube composite material is shown.
