Abstract

We report a facile approach to prepare a cobalt hybrid/graphene (Co/G) nanocomposite via a general one-pot hydrothermal synthesis. NaBH4 is used as the reducing agent. Co/G nanocomposite possesses narrow size-distribution and good dispersion, providing tremendous potential for energy and environment applications. As a proof of concept, we demonstrate the use of the Co/G nanocomposite in a lithium-ion battery and an adsorbent for Congo red (CR), respectively. More importantly, more than 97% of capacity retention (605 mAh g−1) is retained after 50 cycles, indicative of high charge/discharge reversibility of the Co/G nanocomposite electrode. Furthermore the CR removal ability of the Co/G nanocomposite can reach 934.9 mg g−1.
