Sodium dodecyl sulfate intercalated two-dimensional nickel-cobalt layered double hydroxides to synthesize multifunctional nanomaterials for supercapacitors and electrocatalytic hydrogen evolution

Mengyang Zhang et al.

Summary: The controllable adjustment of layered double hydroxide layer spacing has enabled its use as an electrode material for energy storage and electrochemical hydrogen evolution. However, lower conductivity and agglomeration have limited its large-scale application. In this study, sodium dodecyl sulfate (SDS) intercalation modification was used to construct LDH derivatives with vertically grown CoNi-SDS-LDH nanosheets on a nickel foam surface, resulting in a layered structure supported by nanowires which improved ion transport efficiency and reduced agglomeration. The electrode material demonstrated good electrochemical performance, with a cycling stability of 91% after 10,000 cycles and 98.1% performance retention after 10 hours of hydrogen evolution test. This anionic modification offers the potential for large-scale applications of LDH in flexible supercapacitors and electrocatalytic hydrogen evolution.
