Embodiment 1
[0016] Embodiment 1: The preparation method of the zigzag chain thiometal cluster functional material with visible light catalytic performance of the present invention comprises the following steps:
[0017] The first step is to add tungstic acid into the ammonia solution and stir to obtain the ammonia solution of tungstic acid;
[0018] In the second step, hydrogen sulfide is introduced into the aqueous solution of ammonium tungstate prepared in the first step to react, and the compound tetrathioammonium tungstate is obtained through suction filtration and drying;
[0019] In the third step, 0.1 mmol of ammonium tetrathiotungstate was added to 0.4 mmol of cuprous cyanide in 3 ml of N,N'-dimethylformamide solution, and stirred for 20 minutes to obtain a red clear solution;
[0020] In the fourth step, measure 1 milliliter of pyridine and add it to the solution prepared in the third step and stir for 30 minutes to obtain a dark red solution containing a zigzag chain-like thiome...
