MoS3 loaded TiO2 nanoplates for photocatalytic water and carbon dioxide reduction
2016
Abstract 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. MoS 3 /TiO 2 photocatalysts based on TiO 2 nanoplates have been synthesized via a hydrothermal acidification route for water and carbon dioxide reduction reactions. This facile approach generates well dispersed MoS 3 with low crystallinity on the surface of TiO 2 nanoplates. The as-synthesized MoS 3 /TiO 2 photocatalyst showed considerable activity for both water reduction and carbon dioxide reduction. The thermal treatment effects of TiO 2 , the loading percentage of MoS 3 and the crystalline phase of TiO 2 have been investigated towards the photocatalytic performance. TiO 2 nanoplate synthesized through hydrothermal reaction with the presence of HF acid is an ideal semiconductor material for the loading of MoS 3 for photocatalytic water and carbon dioxide reduction simultaneously in EDTA sacrificial solution.
