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.
通过控制三价和二价离子的比例，合成了多过渡金属基层状双氢氧化物（LDH）超薄纳米片。由于催化中心的电子结构得到调制，以及表面积和电子电导率增加，它们表现出先进的析氧反应（OER）性能，过电位低（约0.2 V），并且随着钴掺入量的增加，塔菲尔斜率降低。
