Buckminsterfullerene (C60) was adsorbed onto single-walled carbon nanotubes (SWCNTs) as an electron-acceptor to in-duce intermolecular charge-transfer with the SWCNTs, leading to a class of new metal-free C60-SWCNT electrocatalysts. For the first time, these newly-developed C60-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 C60 electron-acceptor can provide a general approach to high-performance metal-free, pH-universal carbon-based trifunc-tional metal-free electrocatalysts for water splitting and beyond.

C60 吸附 SWCNT 作为无金属、pH 通用和多功能催化剂，用于氧还原、析氧和析氢

Buckminsterfullerene (C60) 被吸附在单壁碳纳米管 (SWCNTs) 上作为电子受体，以诱导与 SWCNTs 的分子间电荷转移，从而产生一类新的无金属 C60-SWCNT 电催化剂。这些新开发的 C60-SWCNT 首次被证明可以在很宽的 pH 范围内作为氧还原反应 (ORR)、析氧反应 (OER) 和析氢反应 (HER) 的三功能无金属催化剂从酸性到碱性的值具有比商业 Pt 和 RuO2 对应物更高的电催化活性和更好的长期稳定性。因此，C60 电子受体的吸附诱导分子间电荷转移可以提供一种通用的方法来实现高性能无金属，
