<p>Herein, for the first time, a gold digital video disc (GDVD) platform was modified layer by layer with the graphitic carbon nitride (g-C₃N₄) nanosheets and gold-platinum nanoparticles (Au–PtNPs), and it was used as an efficient nanocatalyst for the electrocatalytic oxidation of the methanol molecules. The graphitic carbon nitride nanosheets were synthesized through the pyrolysis method, and they were employed as a substrate for the distribution of the Au–PtNPs. The change in the electrochemical behavior of the GDVD surface was investigated in each modification step. The electrocatalytic oxidation of the methanol molecules at the surface of different modified GDVDs was evaluated using cyclic voltammetry (CV) and chronoamperometry techniques. The experimental results indicated that the Au–Pt/g-C₃N₄/GDVD has a higher electrocatalytic activity for the oxidation of methanol under the optimized experimental conditions in comparison with the other studied GDVDs. The kinetic study of the electro-oxidation of methanol was also investigated, and the exchange current density (<i>J</i>₀) values revealed a better kinetic in the presence of graphitic carbon nitride and Au–PtNPs.</p> Graphical Abstract <p></p>
