Two-electron oxygen reduction on fullerene C(60)-carbon nanotubes covalent hybrid as a metal-free electrocatalyst

Nanocarbon materials are considered to be active for electrochemical oxygen reduction reaction (ORR) for hydrogen peroxide (H(2)O(2)) synthesis. In the present work, a new type of fullerene 60 (C(60))-carbon nanotubes (CNTs) hybrid with covalently attached C(60) onto outer surface of CNTs was synthe...

description Nanocarbon materials are considered to be active for electrochemical oxygen reduction reaction (ORR) for hydrogen peroxide (H(2)O(2)) synthesis. In the present work, a new type of fullerene 60 (C(60))-carbon nanotubes (CNTs) hybrid with covalently attached C(60) onto outer surface of CNTs was synthesized. The structure of C(60)-CNT hybrid was confirmed by physical and chemical characterizations and its conformation is proposed featuring the covalent incorporation of CNTs and C(60) derivative. C(60)-CNT hybrid showed high efficiencies on electro-generating H(2)O(2), owing to huge surface area and intermolecular electron-transfer in the hybrid structure. A high H(2)O(2) production rate of 4834.57 mg L(−1) h(−1) (426.58 mmol L(−1)) was achieved at − 0.2 V vs saturated calomel electrode (SCE).
