文摘

Photocatalytic water splitting and carbon dioxide reduction provide us clean and sustainable energy resources. The carbon dioxide reduction is also the redemption of the greenhouse effect. MoS₃/TiO₂ photocatalysts based on TiO₂ nanoplates have been synthesized via a hydrothermal acidification route for water and carbon dioxide reduction reactions. This facile approach generates well dispersed MoS₃ with low crystallinity on the surface of TiO₂ nanoplates. The as-synthesized MoS₃/TiO₂ photocatalyst showed considerable activity for both water reduction and carbon dioxide reduction. The thermal treatment effects of TiO₂, the loading percentage of MoS₃ and the crystalline phase of TiO₂ have been investigated towards the photocatalytic performance. TiO₂ nanoplate synthesized through hydrothermal reaction with the presence of HF acid is an ideal semiconductor material for the loading of MoS₃ for photocatalytic water and carbon dioxide reduction simultaneously in EDTA sacrificial solution.
