In this talk, the basic concept and fabrication technology for the nanodevices for artificial photosynthesis were introduced. Based on the solvothermal and hydrothermal synthesis and alignment of the photocatalytic nanocrystals and its assembled nano-sized monolayers of photocatalytic materials, vectorial electron transport from the higher conduction band energy to lower conduction band energy could be accelerated by suppressing the defect and optimizing the electron transport distance and diffusion capacity. The fabrication of the photocatalysts was done to get the largest exposed surface area of the most photoactive facets for nanocrystals of TiO2, Cu2O, α-Fe2O3 and ZnO. Especially, α-Fe2O3 nanocrystal assembled monolayer fabrication for the visible light sensitive layer on FTO and the measurement of the photocurrent density are the basic approach for the artificial photosynthesis through water splitting and CO2 reduction. For the efficient electron transport through the TiO2 nanotubes, SrTiO3, Fe2O3, Cu2O were filled into the pores of the TiO2 nanotubes and photocurrent was measured.
