Ultrafast construction of 3D ultrathin NiCo-LDH@Cu heteronanosheet array by plasma magnetron sputtering for non-enzymatic glucose sensing in beverage and human serum

NiCo‐LDH coupled with 2D ZIF‐derived Co nitrogen doped carbon nanosheet arrays as a self‐supporting electrocatalyst for detection of formaldehyde

“…TEM image (Figure 1c) further demonstrates the core‐shell nanostructure of Co−N/C@NiCo‐LDH NSAs/CC. HRTEM image (Figure 1d) reveals lattice stripes of 0.23 nm, depicted as NiCo‐LDH (015) planes [26] . This 3D heterostructure can ensure a maximum surface area and expose more active sites, thus significantly increasing its electrocatalytic activity.…”

[26] This 3D heterostructure can ensure a maximum surface area and expose more active sites, thus significantly increasing its electrocatalytic activity. In addition, the energy diffraction spectrum (EDS) mapping (Figure 1e-1i) reveals a homogeneous dispersion of Ni, Co, O, C and N elements on CoÀ N/C@NiCo-LDH NSAs/CC.…”

In situ preparation of hierarchical CuO@NiCo LDH core–shell nanosheet arrays on Cu foam for highly sensitive electrochemical glucose sensing

“…6 In contrast, electrochemical non-enzymatic methods have been widely studied and developed due to their low cost, high sensitivity, rapid response and portability. [7][8][9] Recently, as a typical two-dimensional material, LDHs have been extensively studied by researchers because of their tunable electronic structure and elemental composition. 10 Especially, NiCo-LDH has become a hot spot in the field of electrocatalytic materials because of its abundant oxidation state and rapid electrolyte diffusion reaction.…”
