| 摘 要： | 用伏安法初步研究了激光照射下金电极／溶液界面的电子转移行为。对Ｆｅ＾３＋／Ｆｅ＾２＋，激光照射引起氧化还原峰增高并向阳极方向移动，氧化还原电位负向变化，激光功率对电流－电位曲线的平移幅度具有明显影响。激光照射对抗坏血酸的电子转移作用更显著，电流峰高增加了２．０２倍，过电位减少了０．２５Ｖ。激光能量对电极表面的作用及界面溶液层的影响加速了电子转移并提高了电极反应的灵敏度。

| Abstract: | The preliminary investigation of electron transfer behaviour of Au electrode/solution interface was made on CW laser irradiation by voltammetry.Redox peaks rise and move to the anode direction for Fe 3 /Fe 2 on laser irradiation,redox potentials changed more negative,Laser power has an obvious influence on translation range of current potential curves.The effect of laser irradiation is more remarkble for electron transfer of ascorbic acid,current peak increase by 3.02 times,overpotential decrease 0.25V.Acceleration of electrons transfer and a rise in sensitivity of electrode reaction result from the effect of laser energy to electrode surface and interface solution layer. |
