摘要/Abstract

摘要：

分别采用原位复合和简单混合方法制备了碳点/银(CDs/Ag)复合结构. 原位复合的CDs/Ag对光的吸收和对亚甲基蓝的降解都高于简单混合的CDs/Ag. 研究了H₂O₂和碳点荧光强度对CDs/Ag原位复合结构的影响. 结果表明, H₂O₂的加入量会改变CDs/Ag原位复合结构的形貌与光吸收, 从而导致不同的光催化性能; 用强荧光发射的碳点原位制备的CDs/Ag复合结构具有更好的光吸收特性和更高的光催化活性. CDs/Ag原位复合结构具有高催化活性是由于碳点与纳米银间形成了强化学键, 有利于等离子共振效应发生, 从而促使了光的吸收及能量转化效率的提高.

关键词: 碳点, 银纳米结构, 原位复合, 光催化性能

Abstract:

The composites between carbon dots and silver nanostructures(CDs/Ag) were synthesized by in-situ synthesis and simple mixing, respectively. The products obtained by in-situ synthesis exhibit stronger light absorption and higher photocatalytic activity for methylene blue(MB) degradation than those of simple mixing. The effects of H₂O₂ addition and the fluorescence intensity of CDs on photocatalytic activities of the obtained CDs/Ag were analyzed. The experimental results indicate that the amount of H₂O₂ addition can change the morphology and light absorption of CDs/Ag, and then results in different photocatalytic performances. On the other hand, the CDs/Ag obtained from CDs with stronger fluorescence emission shows stronger light absorption and higher photocatalytic activities. The possible mechanism of photocatalytic activities of the in-situ synthesized CDs/Ag could be that strong combination between CDs and Ag nanocrystals induced much stronger surface plasma resonance, thus enhancing light absorption and the light energy conversion efficiency.
