“Background Owing to their particular physical and chemical properties, carbon spheres (CSs) have attracted much attention of many researchers in different areas [1]. Because of their porous structure [2], high surface area, high electrical conductivity, thermal stability [3], and excellent chemical stability, CSs have been widely used as anode material for lithium-ion battery [4], cathode materials for field emission [5], catalyst support materials [6], and adsorbents [7].
