Buckminsterfullerene (C-60) was adsorbed onto single-walled carbon nanotubes (SWCNTs) as an electron acceptor to induce intermolecular charge-transfer with the SWCNTs, leading to a class of new metal-free C-60-SWCNT electrocatalysts. For the first time, these newly developed Car SWCNTs were demonstrated to act as trifunctional metal-free catalysts for oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) over a wide range of pH values, from acid to alkaline, with even higher electrocatalytic activities and better long-term stabilities than those of commercial Pt and RuO2 counterparts. Thus, the adsorption-induced intermolecular charge-transfer with the C-60 electron-acceptor can provide a general approach to high-performance, metal-free, pH-universal carbon-based trifunctional metal-free electrocatalysts for water-splitting and beyond.
