Synthesis of three-dimensional mesoporous Cu–Al layered double hydroxide/g-C3N4 nanocomposites on Ni-foam for enhanced supercapacitors with excellent long-term cycling stability

In this study, a novel composite of Cu–Al layered double hydroxide (LDH) nanosheets and g-C₃N₄-covered Ni-foam was fabricated via a simple and facile two-step process.
