摘要

Successful synthesis of rGO@Gd2TiIn2O7 nanocomposite (rGO@GTINC) as an effective electrocatalytic material for hydrazine detection is reported. The desirable rGO@GTINC was constructed under a simple hydrothermal method using key precursors in stoichiometric proportions. Advanced analytical and spectroscopic procedures were used to ascertain the structural and physico-chemical characteristics of rGO@GTINC. Characterization results provided critical insights into the well-defined crystalline structure and improved size uniformity achieved through the successful incorporation of rGO within the nanocomposite, ensuring stability and structural integrity. For electrochemical analysis, as-synthesized rGO@GTINC was modified onto a glassy carbon electrode (GCE), resulting in the GCE/rGO@GTINC configuration. Investigations confirmed that the integration of rGO@GTINC into the working electrode significantly enhanced the sensing performance. The electrochemical qualities of rGO enhanced the electron transfer rate, resulting in a lower peak potential and an increased oxidation peak current. The constructed rGO@GTINC sensor demonstrated an extensive linear range of hydrazine sensing (1–120 µmol·L) with a low detection limit of 31 nmol·L−1. The constructed rGO@GTINC sensor’s good recovery rate in the real sample analysis ensures accurate detection and quantification of hydrazine in food samples. The prepared sensor showed acceptable reproducibility, stability, and good selectivity toward hydrazine and provided an effective approach to using electrochemical hydrazine sensing in different food beverages and environmental samples.
