Layered double hydroxides (LDHs) are a class of anionic clay materials. When calcined at a certain temperature range, LDHs decompose into corresponding mixed metal oxides (Ox), which are regarded as promising electrode materials for capacitive deionization (CDI). We have developed a simple yet efficient strategy for in situ assembly of the MgAl-Ox nanosheets on graphene (G). The as-obtained MgAl-Ox/G nanohybrids with numerous channels for the access of anion exhibited high surface area and high electrical conductivity. When used as the anode of CDI cell, MgAl-Ox/G nanohybrids exhibited excellent cycling stability and high electrosorption capacity due to its the memory effect and oxidation resistant property.

煅烧的MgAl层状双氢氧化物/石墨烯杂化物用于电容去离子

层状双氢氧化物（LDHs）是一类阴离子粘土材料。当在一定温度范围内煅烧时，LDH分解成相应的混合金属氧化物（Ox），被认为是用于电容去离子（CDI）的有希望的电极材料。我们已经开发了一种简单而有效的策略，用于在石墨烯（G）上原位组装MgAl-Ox纳米片。如此获得的具有许多用于阴离子进入的通道的MgAl-Ox / G纳米杂化物表现出高的表面积和高的电导率。当用作CDI电池的阳极时，MgAl-Ox / G纳米杂化物因其记忆效应和抗氧化性能而表现出出色的循环稳定性和高电吸附能力。
