您好，谢谢您抽出宝贵的时间替我回复，也找到了类似的相关的合成的其他方法，如：11-Molybdo-l-vanadophosphoric Acid.—Na2HP04, 7.1 g, was dissolved in 100 ml of water and mixed with 6.1 g of sodium metavanadate that had been dissolved by boiling in 100 ml of water. The mixture was cooled and acidified to a red color with 5 ml of concentrated sulfuric acid. To this mixture was added a solution of 133 g of Na2Mo04-2H20 dissolved in 200 ml of water. Finally, 85 ml of concentrated sulfuric acid was added slowly with vigorous stirring of the solution. With this addition the dark red color changed to a lighter red. The heteropoly acid was then extracted with 400 ml of ethyl ether after the water solution was cooled. In this extraction, the heteropoly etherate was present as a middle layer; the bottom layer (water) was yellow and probably contained vanadyl species. After separation, a stream of air was passed through the heteropoly etherate layer to free it of ether. The orange solid that remained was dissolved in 50 ml of water, concentrated to the first appearance of crystals in a vacuum desiccator over concentrated sulfuric acid, and then allowed to crystallize further. The orange crystals that formed were filtered, washed with water, and air dried. The yield was 28 g. The crystalline acid effloresces slowly at room temperature; thus the amount of water of crystallization varied slightly from sample to sample. Reference： Molybdovanadophosphoric Acids and Their Salts. I. Investigation of Methods of Preparation and Characterization.(1968),这种方法我个人觉得也不简单，还需要调节PH ，更加的麻烦，请问您一般用什么方法合成呢？
