The invention discloses a method for synthesizing regular flower-ball-shaped nanometer sulfur indium magnesium by a one-pot method, and relates to the technical field of inorganic synthesis. The preparation method specifically comprises the following steps: S1, uniformly dispersing a magnesium source, an indium source and polyvinylpyrrolidone in deionized water to obtain a magnesium-indium solution; s2, adding cysteine into the indium-magnesium solution, and stirring to obtain a precursor solution; s3, transferring the precursor solution into a high-pressure reaction kettle, carrying out heating reaction, and carrying out post-treatment to obtain ball-flower-shaped nano indium magnesium sulfide; the nano sulfur indium magnesium prepared by the method has regular flower-ball-shaped morphology, the sphere particle size is as low as 800nm, and the nano sulfur indium magnesium has excellent photocatalytic activity.

The present application relates to the technical field of inorganic synthesis, and provides a preparation method of cis-diiododiammine platinum (II). The present application dissolves potassium chloroplatinite in a polar solvent to obtain a potassium chloroplatinite solution; iodine source and nitrogen source are sequentially added into the potassium chloroplatinite solution to react, so as to obtain the cis-diiododiammine platinum (II). The present application uses potassium chloroplatinite, iodine source and nitrogen source as raw materials, can promote the efficient reaction under mild conditions, and improves the reaction efficiency and product yield. The results of examples show that the reaction time is only 0.5 h when the cis-diiododiammine platinum (II) is prepared by the method of the present application, and the product yield can reach more than 95%. In addition, the process of the present application is simple, the synthesis route is short, the safety is good, the raw materials are cheap and easy to obtain, and the present application is suitable for industrial batch production.
