Small-sized Pt–Ni nanoparticles were synthesized into hollow porous carbon spheres (HPCS) under molecule assistance. Pt–Ni nanoparticle/HPCS prepared in presence of 2,2′-Dipyridylamine showed excellent oxygen reduction reaction activity/durability.
An anode of hard carbon spheres with both small size and a porous structure enables superior electrochemical performance of potassium-ion batteries.
Various synthetic techniques are employed to fabricate porous carbon spheres and monoliths for improved performance as Li-ion battery anode materials.
This paper describes the preparation of graphitic porous carbon spheres (GPCS) from spherical resorcinol/formaldehyde resin by Fe-catalysis at 900 °C.
