Abstract:We present a groundbreaking technique for controllably synthesizing nanosized semiconductive two‐dimensional (2D) (Cu–S)n metal–organic framework (MOF)/graphene nanocomposites for electrochemical sensing of neurotransmitter 2‐phenethylamine (PEA). The (Cu–S)n MOF size is controlled by graphene oxide proportions, enhancing electrocatalytic activity. The modified electrode exhibits a surface area increase from 0.0639 to 0.1906 cm2 and impressive limit of detection (0.0156 and 0.004 μM) within linear ranges of 15… Show more
