Copper‐based materials derived from metal‐organic frameworks for electrochemical sensing of hydrazine

An effective and rapid method for the detection of hydrazine hydrate is urgently needed as a result its high toxicity extensive use. Here, copper nanoparticles supported on carbon (written as: Cu NP/C) oxide polycrystalline solids CuO PS), synthesized by calcining same metal–organic framework at temperature, were respectively used electrode materials electrochemical sensing hydrazine. The results show that prepared NP/C exhibits better performance with sensitivity 0.1726 mA (mmol/L)−1, wider linear range 0.1–2.4 mM lower limit 0.0014 mmol·L−1, compared to obtained PS. This can be reasonably explained valence state interaction supports in NP/C. Furthermore, good selectivity anti-interference ability from are also acquired
