    摘要:
    我们报告了单金属的Co 2+ / Co 3+层状双氢氧化物的制备,其间嵌入有乳酸根阴离子(LCoH-乳酸),并在水中自发分层,形成了氢氧化钴纳米片。这些氢氧化物纳米片形成稳定的水分散体。通过原子力显微镜和小角度X射线散射实验,纳米片的厚度估计为约1nm,并且对应于单个氢氧化物层。一些Co 2+阳离子被氧气氧化,导致混合的Co 2+ 0.76 Co 3+ 0.24层组成。在水蒸发后,纳米片重新堆叠以形成具有类似于原始材料的层状结构的透明自立膜。纳米片并排堆叠的表面覆盖表示二维团聚,表明这些分散体可用于制备纳米单片的大单层。通过旋涂制备的层是稳定的,并且在碱性电解质中具有可逆和可再现的氧化还原特性。在对其电化学性能的评估中,氢氧化钴纳米片在高达200 mV s -1的重复电势循环过程中表现出耐久性和快速的电荷转移动力学。通过本方法制备的纳米片显示出有望用于能量存储应用的纳米复合材料。
