Local Heating Induced Single-Crystalline Phase Control in Electrochemical Synthesis of Nanomaterials

Abstract

Synthesis of electrochemical crystalline nanomaterials have a great advantage. The single crystalline material synthesized by the existing solvothermal synthesis method often has no catalytic activity due to contamination on the surface during the synthesis process. Therefore, in this study, the electrochemical single crystalline nanomaterials induced by heat were clearly synthesized. Since a process of thermal post-treatment of nanomaterials require a high temperature, thermal induced electrochemical synthesis was lowering the thermal energy barrier.In this study, copper, silver, gold, and platinum single crystalline nanoparticles were synthesized and characterized through SEM, TEM, and SAED. In the synthesis process, the growth process according to deposition coulomb was observed. And the catalytic activity of the synthesized single crystalline nanomaterials was measured.
