Abstract:
We report La-modified Co3O4 nanosheet arrays, in which La incorporation regulates the electronic configuration of Co sites, resulting in overpotentials reduced by 60 and 74 mV for OER and HER, respectively, compared to pristine Co3O4, and enabling efficient overall water splitting with a cell voltage of 1.73 V.
