We produced a nano TiO2 coating on SnO2: F (FTO) electrodes in an aqueous solution. Anatase TiO2 crystallized in the transparent solution at 50°C for 10 min. The FTO electrodes with markedly uneven surface were successfully covered by nano TiO2 without annealing. The TiO2 was deposited on the electrodes with no clearance, thus attaining high adhesion strength. The coating showed high transparency, over 75%, in visible-light regions of 400 to 800 nm, which is similar to bare FTO electrodes. The electrodes had a unique surface structure resulting from the combination of uneven FTO surface and microasperity due to the nano TiO2 coating.
