Size Dependent Electrocatalysis of Gold Nanoparticles

摘要: Gold is a rather inert metal. Many chemical and electrochemical heterogeneous reactions are not catalyzed efficiently on gold. However, number of reactions, especially gas phase have shown significant reaction rates at nanosized gold particles. In electrochemistry, there strong need for highly efficient electrocatalysts to accelerate therefore increase the energy efficiency these reactions. This important conversion storage sensor applications. Since beginning 21st century, research application nanoparticles in electrocatalysis has intensified. Significant efforts devoted understand impact size shape their structural, electronic other physical properties how influence Very versatile synthesis techniques been developed that permit control both particles with narrow particle distribution. article focuses size-dependent nanoparticles. Different preparation methods shortly summarized. The oxygen reduction acidic alkaline medium discussed detail. Other glucose oxidation reaction, briefly mentioned.
