摘要: |
beta-SiC nanowires were synthesized by simple carbothermal reduction of a mixture composed of low-cost water glass and starch, and characterized by XRD, SEM, TEM, BET, UV-visible absorption, FT-IR spectrometer and X-ray photoelectron spectrometer. The results show that the beta-SiC nanowires can absorb visible light and exhibit excellent photocatalytic hydrogen evolution performance from pure water under visible light irradiation. The hydrogen evolution rate can reach more than 60 mu L/g.h. siC nanowires by simple modification can greatly enhance the efficiency of H(2) production. Average H2 production rate over the modified SiC is 76.1% higher than that of unmodified SiC. The enhanced H(2) production is mainly due to stronger hydrophilic ability of the modified SiC. In addition, O(2) is detectable in the experiment, indicating that water has been decomposed into H(2) and O(2). |
