【摘要】

：

本研究应用简单溶液回流及煅烧处理方法制备出钴掺杂氧化锌纳米颗粒/还原氧化石墨烯(Co-doped ZnO NPs@rGO)复合材料.实验发现,当钴掺杂浓度为0.38时,Co0.38Zn0.62O NPs@rGO复合材料表现出良好的氧气还原电催化性能：起始电位为0.90 V,极限电流密度为3.94 mA cm-2,且反应以四电子氧气还原为主,并具有优于传统商用Pt/C催化剂的电化学稳定性和抗甲醇性.

单层黑磷薄膜材料中声子诱导的量子退相干过程的温度效应

量子相干时间短有利于延长激发态寿命，可以降低非辐射电子-空穴复合，这对提高太阳能电池光电转换效率大有裨益。电子与声子的相互作用破坏电子态间的量子相干性，而温度高低影响了原子核运动的快慢，进而影响电声相互作用强弱和量子退相干过程的快慢。
