A method for titanium dioxide coating includes following steps. An electrolyte containing Ti3+, an oxidant, and at least one of NO3- and NO2- is provided, wherein the oxidant is configured for substantially oxidizing Ti3+ into Ti4+. A substrate is immersed into the electrolyte and provided with cathodic current to the substrate for reduction of NO3- or NO2- to genenerate hydroxyl ion. A titanium dioxide film is thus formed at the substrate surface. The present invention displays the advantages of adjustable deposition rates due to the controllable structure of Ti4+ intermediates in the deposition solution, thickness, porosity, and morphology control by varying the electroplating parameters, relatively uniform deposits on complex shapes, and low cost of instruments.
