The invention discloses a room-temperature ionic liquid based on polyoxometallate and a preparation method of the room-temperature ionic liquid, relates to a room-temperature ionic liquid and a preparation method thereof, and aims to solve the problems that conventional polyoxometallate ionic liquids are small in variety and number and is in a non-liquid state at the room temperature. The room-temperature ionic liquid based on polyoxometallate consists of titan yellow cation, polyoxometallate anion and a solvent, wherein the chemical formula of the titan yellow cation is [C28H19N5O6S4]<2+>; the chemical formula of the polyoxometallate anion is [X2M18O62]<4-> or [XM12O40]<4->. The preparation method comprises the following steps: I, preparing a mixed organic solution containing [X2M18O62]<4-> or [XM12O40]<4-> cation; II, preparing a titan yellow solution; III, mixing; IV, removing impurities, so as to obtain the room-temperature ionic liquid based on polyoxometallate. The invention mainly aims to perpare room-temperature ionic liquids. |
