文摘

An enhanced non-enzymatic electrochemical sensor of nitrite was designed by immobilizing high-quality palladium nanocubes decorated nitrogen-doped graphene (NGE/PdNC)nanocomposites on a GCE. The wide linear range and high sensitivity for nitrite sensing were identified as 5.0×10-7 − 1.51×10-3 mol L-1 and 342.4 μA mM−1  cm−2, respectively. The NGE/PdNC/GCE also showed a high reproducibility, stability and good selectivity.
