Main observation and conclusion Detection of hydrazine originated from electrochemical media has recently gained considerable attention in the sensing field. Herein, to improve electron transfer capacity, a polyoxometalate metal‐organic framework (POMOF, NENU‐3) is in‐situ nucleated onto the carboxyl functionalized reduced graphene oxide (CFG) (NENU‐3/CFG, abbreviation N3/CFG). The N3/CFG supported onto carbon cloth electrodes (CCEs) has been investigated for hydrazine detection. The amperometric results display that the POMOF/CFG to hydrazine has a broad linear range (0.09—362.5 μmol/L) and low detection limit (24 nmol/L). In addition, the POMOF/CFG‐based sensors possess good anti‐interference capability, boosted stability and feasibility. Furthermore, when applied to the detection of practical samples, acceptable relative recoveries of 96.26%—107.30% are obtained.
