Embodiment 1
[0019] Add 0.50 g tourmaline powder sample into 40 mL deionized water, stir magnetically for 30 min, and ultrasonically disperse for 30 min, then add 1.25 g copper acetate and stir until completely dissolved to obtain suspension A. Weigh 0.50 g of sodium hydroxide and dissolve it in 20 mL of deionized water to obtain solution B. Under magnetic stirring, solution B was added dropwise to suspension A and stirred continuously for 2 h to obtain suspension C. Finally, the suspension C was put into a 100 mL polytetrafluoroethylene reactor, reacted at 180 °C for 6 h, cooled to room temperature naturally, washed with deionized water, dried at 60 °C, and ground to obtain a zero-dimensional / two-dimensional structure oxidation Copper and tourmaline composite photocatalytic materials, in which the average size of zero-dimensional copper oxide nanoparticles is 10-20 nm, and the average size of two-dimensional copper oxide nanosheets is 200-450 nm.
Embodiment 2
[0021] Add 0.50 g tourmaline powder sample into 40 mL deionized water, stir magnetically for 30 min, and ultrasonically disperse for 30 min, then add 2.50 g copper acetate and stir until completely dissolved to obtain suspension A. Weigh 1.00 g of sodium hydroxide and dissolve it in 20 mL of deionized water to obtain solution B. Under magnetic stirring, solution B was added dropwise to suspension A and stirred continuously for 2 h to obtain suspension C. Finally, the suspension C was put into a 100 mL polytetrafluoroethylene reactor, reacted at 180 °C for 6 h, cooled to room temperature naturally, washed with deionized water, dried at 60 °C, and ground to obtain a zero-dimensional / two-dimensional structure oxidation Copper and tourmaline composite photocatalytic materials, in which the average size of zero-dimensional copper oxide nanoparticles is 15-20 nm, and the average size of two-dimensional copper oxide nanosheets is 250-480 nm.
Embodiment 3
[0023] Add 0.50 g of tourmaline powder sample into 40 mL of deionized water, stir magnetically for 30 min, and ultrasonically disperse for 30 min, then add 2.50 g of copper acetate and stir until completely dissolved to obtain suspension A. Weigh 1.00 g of sodium hydroxide and dissolve it in 20 mL of deionized water to obtain solution B. Under magnetic stirring, solution B was added dropwise to suspension A and stirred continuously for 2 h to obtain suspension C. Finally, the suspension C was put into a 100 mL polytetrafluoroethylene reactor, reacted at 160 °C for 6 h, cooled to room temperature naturally, washed with deionized water, dried at 60 °C, and ground to obtain a zero-dimensional / two-dimensional structure oxidation Copper and tourmaline composite photocatalytic material, in which the average size of zero-dimensional copper oxide nanoparticles is 10-20 nm, and the average size of two-dimensional copper oxide nanosheets is 200-420 nm.
