By controlling the ratio of tri- and bi-valent ions, multi-transition metal based layered double hydroxide (LDH) ultrathin nanosheets are synthesized. They show advanced OER performance with low overpotentials (∼0.2 V) and decreased Tafel slopes with increasing Co incorporation due to the modulated electronic structures of catalytic centers and the increased surface area and electronic conductivity.
