Embodiment 1

[0046] About (C 6 h 12 NH 2 ) 2 BiBr 5 The synthesis of raw material adopts water / ethanol (both volume ratio is 1:1) as mixed solvent, with C 6 h 12 NH, Bi 2 o 3 Mix the three initial raw materials with HBr according to the molar ratio of 4:1:10, and the reaction equation is as follows:

[0047] 4C 6 h 12 NH+Bi 2 o 3 +10HBr=2(C 6 h 12 NH 2 ) 2 BiBr 5 +3H 2 o

[0048] Concrete implementation steps: 0.04mol C 6 h 12 NH and 0.01mol Bi 2 o 3 Add to 30ml of water / ethanol mixed solvent, slowly add 0.1mol HBr under the condition of vigorous stirring, and gradually dissolve the precipitate in the solution as the reaction proceeds; continue to add 0.05mol HBr to adjust the pH value of the solution, and then the obtained The solution is subjected to microporous filtration, and the solvent is evaporated to dryness to obtain the raw material.

Embodiment 2

[0050] Different from Example 1, the C 6 h 12 NH 2 Br, BiBr 3 The three initial raw materials of HBr and HBr are mixed and reacted according to the molar ratio of 2:1:5. Regulate the amount of added HBr to control the solution pH value in the reaction process, finally can obtain identical (C 6 h 12 NH 2 ) 2 BiBr 5 compound.

Embodiment 3

[0052] Different from Example 1, the C 6 h 12 NH 2 Cl, BiCl 3 The three initial raw materials of HBr and HBr are mixed and reacted according to the molar ratio of 2:1:6. Regulate the amount of added HBr to control the solution pH value in the reaction process, finally can obtain identical (C 6 h 12 NH 2 ) 2 BiBr 5 compound.
