Here, we present an attractive approach to construct electronic rich Pt single atoms and nanocrystals via simple electrochemical cycling. Hollow carbon nanoballoons decorated with cobalt were used as support, which...
Recently, hollow carbon spheres (HCSs) have drawn intensive attentions towards supercapacitors due to their inherently structural merits. However, the exploration of simple yet efficient activation strategies is always a challenge...
The upsurge of potassium-ion energy storage devices promotes the fast development of K-ion storage electrode materials, but the poor kinetics and low capacity resulted from the large size of K-ions...
