Electrochemical deposition of electronic rich Pt single atoms and nanocrystals on porous carbon for enhanced electrocatalysis in strong acid

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...

Green self-activation engineering of metal-organic frameworks derived hollow nitrogen-doped carbon spheres towards supercapacitors

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...

Intercalation pseudocapacitance of hollow carbon boxes with multilayered shells for boosting K-ion storage

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...
