Abstract：Electrochemical energy technologies have been hailed as viable alternatives to fossilfuel-based technol-ogies in providing necessary energy for a wide 

range of practical applications. One major challenge is the development of effective catalysts to enhance the electron-transfer kinetics involved and hence the 

overall performance. There are several critical reactions, such as oxygen reduction reaction in fuel cells and met-al-air batteries, hydrogen evolution reaction 

and oxygen evolution reaction in water splitting,etc.,where the catalysts of choice are conventionally based on precious metals, such as Pt, Ir and Ru. It is 

therefore of both fundamental and technological significance to develop electrocatalysts based on low-cost,earth-abundant materials that can rival the traditional benchmarks. In this presentation, we will highlight results from several recent studies where we demonstrate that metal/carbon nanocomposites, in particular, 

carbon-supported single metal atom composites, can serve as effective electrocatalysts towards thevarious reactions, with a performance competitive or superior to those of the commercial benchmarks. The mechanistic origin is unraveled by a deliberate integration of theory and experiment.
