Electrodeposition from a lyotropic liquid crystal template medium was used to produce nanostructured platinum microelectrodes with high specific surface area and high mass transport efficiency. Compared to polished and conventional platinized microelectrodes, well-ordered nanostructured platinum microelectrodes exhibited enhanced electrocatalytic properties for oxygen and ascorbic acid, whilst well-ordered nanostructured platinum microelectrodes offered improved electrocatalytic properties for oxygen reduction compared to disordered nanostructured platinum microelectrodes.

在NiE(E=S,Se)纳米粒子辅助下,采用CVD方法,在NiE(E=S,Se)-Zn系统中成功生长出立方闪锌矿结构一维ZnE(E=S,Se)纳米线.生长的ZnSe和ZnS纳米线长度达几十微米,具有接近理想化学计量比的成分和较高的结晶质量.研究表明,ZnE纳米线生长过程中,ZnNi合金充作实际的催化剂,生长遵循氧化还原反应助VLS机理.基于此机理,通过调控NiE纳米粒子的尺寸可以有效控制ZnE纳米线的直径.
