摘要：
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 (similar to 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.
