Abstract

Electrochemically generated NiOx nanoworms from a neutral bicarbonate system split water into dioxygen and protons with tremendous efficiency and stability. The NiOx electrocatalyst follows a pH-potential dependence, revealing a PCET (proton coupled electron transfer) mechanism of one electron and one proton oxidation. It does not require proton abstracting phosphate or borate buffers for electrogeneration and catalysis, and shows promising activity for anodic oxidation of water in phosphate, borate, and carbonate buffers. © 2014 WILEY-VCH Verlag GmbH & Co.
