The invention discloses nano iridium oxide and a preparation method and application thereof.The preparation method of the nano iridium oxide comprises the following steps that S1, iridium salt is dissolved in water, an alkaline substance is added to adjust the pH value of the solution to 11-12, and an iridium salt solution is obtained; s2, adding a reverse micelle surfactant to obtain a reverse micelle solution A; s3, adding a reverse micelle surfactant into the weak base solution to obtain a reverse micelle solution B; s4, mixing the reverse micelle solution A with the reverse micelle solution B, and dispersing under ultrasonic and monochromatic light irradiation conditions to obtain an iridium oxide colloidal solution; s5, adding an acidic substance, and regulating the pH value of the solution to 7-8; and S6, centrifugally filtering the mixed solution obtained in the step S5, and sequentially carrying out ultrasonic washing, vacuum drying and roasting on the obtained precipitate to obtain the nano iridium o
