Abstract: |
The invention relates to a Titania crystal adsorption enhancement film electrode and relative production, wherein said film electrode is formed by the conductive substrate and the composite layer formed by the first layer of dense TiO2 film and the second layer of large-hole film layer; the first dense TiO2 film is formed by the titania particles whose diameter is 2-5nm; the second layer is formed by the titania particle whose diameter is 5-60nm and the ball air hole whose diameter is 80-1500nm. Said Titania dense film can effectively baffle the electron combination between the electrolyte and the conductive substrate; the large-hole emission film has hundreds of nanometer air large holes on the film material, with high light diffuse property. |
