We fabricated two-dimensional crystalline composite colloidal layers on FTO glass using the suspension of Poly(methyl methacrylate) (PMMA) microspheres and TiO2 nanoparticles. Subsequently, TiO2 inverse opal structure was obtained upon calcination of composite monolayer films, to be utilized for photo-electrode for water splitting. We studied the correlation between thickness of TiO2 inverse opal film and particle size of doped Gold nanoparticles on photocurrent density from water splitting. We could modulate the thickness of TiO2 inverse opal film by changing the rate of spin coating. The size of doped Au particles which can efficiently absorb visible light by surface plasmon resonance effect could be controlled by adjusting the deposition time. Consequently, we could procure more effective results of photocurrent density from water splitting. |
