Layered double hydroxides (LDHs) are getting considerable attention as electrode modifiers in electrochemical sensing applications. They are unique materials because of their two-dimensional structures, highly tunable interior architecture, excellent ion exchange capabilities, reasonable interlayer spaces, and high porosities. They are easy to synthesize from commonly available inorganic precursors. In electrochemical sensing, they provide a stable environment for immobilization of the enzymes or other sensing materials. LDHs have been used both in pure form or in combination with other materials to address certain issues in electrochemical sensing. LDHs modified electrodes may also improve sensitivity and selectivity toward the detection of certain target analytes by pre-concentrating/accumulating target species. In this review, we provide an overview of recent advancements in LDH based electrochemical sensors for environmental analysis.

作为电化学传感应用中的电极改性剂，层状双氢氧化物（LDH）受到了广泛的关注。它们具有二维结构，高度可调的内部结构，出色的离子交换能力，合理的夹层空间和高孔隙率，因此是独特的材料。它们很容易从常用的无机前体中合成。在电化学传感中，它们为固定化酶或其他传感材料提供了稳定的环境。LDH已以纯净形式或与其他材料组合使用，以解决电化学传感中的某些问题。LDHs修饰电极还可以通过预浓缩/积累目标物质来提高对某些目标分析物检测的灵敏度和选择性。在这篇评论中
