Abstract

Developing effective, stable, and economical nanomaterials is critical for the further implementation of fuel cells, water electrolysis, metal-air batteries, and other clean energy storage and conversion devices [1,2]. To realize controllable design and synthesis of the required functional nanomaterials, the most efficient way is to reveal their growth mechanisms through monitoring the phase transition, morphological and compositional evolution, etc. during their (electro)chemical synthesis. In this regard, transmission electron microscopy (TEM) and its associated in-situ techniques offer the feasibility of revealing the reaction kinetics at the nanoscale, even at the atomic level, as they can directly disclose the microstructure, composition, and structural changes of various nanomaterials under different external fields [3,4]. In this talk, I will introduce some of our recent in situ TEM studies of functional nanomaterials under external fields such as heat, electricity, cooling, etc.
