| Summary: | 碩士 === 國立東華大學 === 光電工程學系 === 107 === Synthesis of zinc oxide heterostructure by the low cost process was proposed in this investigation for photoelectochemical applications. Synthesis of defects-rich zinc oxide was achieved by hydrothermal method of low temperature at 65℃. The photocurrent of defects-rich zinc oxide shows 0.76 mA/cm2 at the potential of 1 V.
The bismuth ions were reduced to bismuth metal particles on the surface of zinc oxide with a particle size of 5 ~ 10 nm for photoelectrochemical (PEC) hydrogen generation and surface enhanced Raman scattering (SERS). The photocurrent has 0.66 mA/cm2 at the potential of 0.3V. In terms of surface-enhanced Raman scattering, the enhancement factor was 7.5×105 for proline as target material.
Synthesis of ZnO/In2O3/CuO core-shell nanowires by the low cost process was proposed in this investigation for photoelectrochemical hydrogen generation. The photocurrent has 70% enhancement of the photocurrent in comparison to the pristine ZnO and the CuO/In2O3/ZnO core-shell photoelectrode produces 3 µmol of hydrogen per hour.
This work demonstrated that zinc oxide heterostructure is an effective electrochemical electrode meterial structure in photoelectrochemical.
