Abstract:

It is a current research focus for bottom-up designing high performance nono-gold catalyst. This paper introduces the advanced synthesis routes on the basis of citric acidmercaptan and dendrimer methodsthese controlled synthesis would clarify nano-structure and beneficial for supporting. Progress of chemical and electrochemical catalysis with nano-gold are analyzedand it is realized that the exploration on the quantum double-layer and molecular-like effects in electro-catalysis would likely make breakthrough in the fields of fuel cell and biosensor.

摘要:

由基础出发设计高性能金纳米催化剂是当前的研究热点,本文介绍了以柠檬酸法、硫醇法、树形大分子为基础的前沿合成路线,其可控性合成可促进纳米结构清晰并利于载体担载;进而分析了金纳米在化学及电化学催化上的进展,认为电催化中量子双电层效应、类分子效应的探索有望在燃料电池、生物传感器应用方面取得突破。
