摘　　要：本文研究了糠醛在不同电压下,吸附在铜电极表面的SERS光谱.同时糠醛分子是以化学吸附的方式吸附在铜金属表面上的,而且我们用DFT理论对糠醛分子在铜电极上的SERS光谱进行了指认.实验结果表明,糠醛在铜电极表面的吸附方式随电极电压的改变而变化.we have studied SERS spectra of furfural molecule absorded on the surface of copper electrode under different voltages. Simultaneously, the chemical chelation Was used to explain the interaction mechanism between furfural molecules and copper electrode. Moreover,the SERS spectrum of FurfurM was calculated with density functional theory（DFT）. The experimental results showed that the absorded manners of furfural molecule varied with change of the electrode voltage.
