摘要： 利用电化学扫描隧道显微镜(ECSTM)在温和的电化学和隧道偏压的条件下诱导电极表面发生特定的局域电化学反应, 在Au(111)单晶电极表面构筑了Pd纳米粒子的阵列. 研究了两种不同的溶液体系(PdCl2和PdSO4)构筑纳米粒子所需设定的不同参数, 同时探讨了选择不同参数的原因.

Abstract: Electrochemical scanning tunnelling microscope (ECSTM) was used to induce local electrodeposition under mild electrochemical and tunnelling bias conditions. The Pd nanocluster arrays were fabricated on Au(111) in PdCl2 and PdSO4 solutions respectively and different parameters for nanostructructuring were explored in the corresponding solutions.

Key words: ECSTM, Pd nanoclusters, Nanostructuring
