Abstract: By varying the hydrolysis and hydrothermal processing parameters in preparing TiO2 nanoparticles different sizes of TiO2 nanoparticles are obtained.(1) At higher autoclaving temperature,lower pH and longer autoclaving period,larger sizes of TiO2 nanoparticles are prepared.(2) The nanoporous electrodes made from sintering smaller TiO2 nanoparticles show relatively poor IPCE and low absorption in UVVis spectrum,(3) Higher IPCE can be achieved with TiO2 nanoporous electrodes made from sintering larger TiO2 nanoparticles.These electrodes are suitable for studying behavior of the photoelectrochemistry of dye sensitized nanoporous electrodes.
