摘要
Here, we report a novel highly efficient cobalt-based catalyst for the oxygen evolution reaction (OER), which consists of similar to 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 loadingmass. 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 efficientOER electrocatalysts.
