This invention discloses a method for preparing tin dioxide hydrated colloidal precursors via dual-anode synchronous electrolysis, belonging to the field of electrochemical preparation technology of inorganic functional materials. The method includes the following steps: a) preparing an electrolyte containing 0.01 M hydrochloric acid and adjusting the initial pH value; b) using a high-purity tin plate as anode 1 and a titanium-based size-stabilized electrode as anode 2; using the titanium-based size-stabilized electrode as a common cathode; c) applying a DC voltage for constant-voltage synchronous electrolysis; anode 1 dissolves to generate stannous ions, anode 2 electrolyzes chloride ions to generate hypochlorous acid, and the hypochlorous acid instantly oxidizes the stannous ions to tetravalent tin ions in the bulk solution far from the cathode, forming a translucent tin dioxide hydrated colloidal precursor in situ in an acidic medium; d) drying the resulting colloid under reduced pressure and then calcining it at 200–250℃ to obtain high-purity nano-tin dioxide. This invention achieves integrated "dissolution-oxidation-gelation" through dual-anode synergy, avoiding the loss of hypochlorous acid during cathode reduction.
