Ultra-tiny Co(OH)2 particles supported on graphene oxide for highly efficient electrocatalytic water oxidation

Abstract

Here, we report a novel highly efficient cobalt-based catalyst for the oxygen evolution reaction (OER), which consists of ∼2 nm Co(OH)2 clusters supported on graphene oxide (Co(OH)2/GO). Compared with hydrothermally treated Co3O4/GO (HT-Co3O4/GO) reported in the literature, Co(OH)2/GO shows comparable OER performance but with 42% less cobalt loading mass. The turnover frequency (TOF) of Co(OH)2/GO is 2.8 times as high as that of HT-Co3O4/GO. Our result presents a new opportunity for researchers to design efficient OER electrocatalysts.
