摘要：

This study looks at the formation of g-C3N4@CuNi nanoparticles with good electrocatalytic properties. UV-DRS, FT-IR, XRD, SEM, EDX, XPS, BET, and HR-TEM techniques were used to characterise the produced g-C3N4@CuNi nanoparticles. The energy gap values like 3.4 eV, 3.2 eV, and 2.7 eV for g-C3N4, CuNi bimetallic, and gC3N4@CuNi NPs, respectively. Electroanalysis on core-shell nanoparticles demonstrated dopamine's electrocatalytic activity. The sensor has a detection limit (S/N = 3) of 0.001 M, a sensitivity of 198.12 mu A mM-1 cm-2 and a high recovery in real sample analysis, indicating its practical viability. A novel electrochemical sensor could be created by combining g-C3N4 and CuNi bimetallic NPs.
