| Summary: | 碩士 === 國立成功大學 === 材料科學及工程學系 === 106 === Multi-component photocatalysts based on g-C3N4 was synthesized to enhance the photocatalytic performance of g-C3N4. Exfoliated g-C3N4 was fabricated by heating melamine at 550°C, followed by the use of hydrogen peroxide (H2O2) to exfoliate bulk g-C3N4. Mesoporous TiO2 beads were prepared using a two-step process. α-MoO3 nanobelts were made by the hydrothermal method. Two groups of binary-component photocatalysts of TiO2 mesoporous beads/exfoliated g-C3N4, and α-MoO3 nanobelts/ exfoliated g-C3N4 having various compositions were then made. Based on the performance of these binary-component photocatalysts, α-MoO3 nanobelts/ mesoporousTiO2 beads/exfoliated g-C3N4 ternary composite photocatalysts were synthesized. The photocatalytic performance of all the single-binary and ternary component photocatalysts was evaluated by degrading methyl blue under both UV and visible light irradiations.
