Electrochemical sensor based on laser scribed graphitic carbon nanosheets loading palladium nanoparticles: Ultrasensitive detection of hydrazine

Abstract

We use a simple and inexpensive technique to fabricate the graphitic carbon nanosheets based on laser graphenization of polyimide (PI) sheets in just a few minutes. Combined with laser graphenization, we prepared laser scribed graphitic carbon nanosheets loading palladium nanoparticles (Pd/LSGCNs), synthesized by laser graphenization obtaining conductive graphene and electrodeposition getting Pd, which could be manufactured quickly and easily. The morphology and microstructure of Pd/LSGCNs were characterized by scanning electron microscopy (SEM), Raman, X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) measurements. Pd/LSGCNs is used for electrochemical sensor. The electrochemical response of Pd/LSGCNs toward hydrazine oxidation was researched by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV), illustrating superior electrocatalytic activity toward hydrazine. The proposed Pd/LSGCNs sensor was used for hydrazine determination with the linear range of 0.12-888.82 μM, good sensitivity and high selectivity, which is a promising candidate for hydrazine sensor in more practical applications due to its excellent catalytic performance and simple and rapid synthesis methods.
