| 摘要: |
Nanostructured SiC was employed as the catalyst for photocatalytic hydrogen production from water
splitting under visible light irradiation. The SiC materials with different morphologies (whiskery, wormlike
and particulate) were prepared by the carbothermal reduction using different carbon and silica
precursors. The photocatalytic hydrogen evolution was evaluated from pure water without any sacrificial
agent. The results show that the SiC with different morphologies presents different photocatalytic hydrogen
evolution performance. The average hydrogen evolution rates over the particulate and worm-like
SiC are 83.9 L/g h and 82.8 L/g h, respectively, which are much higher than that over the SiC whiskers
(45.7 L/g h). The difference in the photocatalytic performance can be ascribed to the different specific
surface areas and morphologies. |
