We also present high-efficiency artificial photosynthesis electrochemical cell by focusing high efficiency plasmon generation in meta-structure, using the meta-structure of TiO2 photocatalyst. Our propose photoelectrode of combined photocatalyst with meta-structure has Au layer thickness of 50 ~ 100 nm on FTO, and TiO2 layer deposited thickness of 10 ~ 200nm, and Au dot is formed on TiO2 layer. Briefly, TiO2 photocatalyst is located between Au dot and the Au layer, and hydrogen production efficiency is improved by the plasmon resonance energy of meta-structure transfer in the TiO2 photocatalyst. We report improvement of photocatalytic efficiency and dependent of light absorption by the TiO2 thickness and the Au dot size. |
