The study effectively highlights the importance of stabilizers in enhancing the performance of Pd–Ni-rGO electrocatalysts. However, one observation stands out: the significant conductivity difference between H–Pd–Ni-rGO and CH–Pd–Ni-rGO. Could the authors provide additional insights into why the combination of CTAB and HMTA results in such low conductivity, despite both agents having stabilizing effects individually?
Moreover, the reported improvements in performance are attributed to HMTA’s role in stabilizing the nanoparticles. Have the authors considered using advanced characterization techniques, such as XPS or HR-TEM, to confirm whether HMTA influences the metal-support interactions or nanoparticle dispersion more effectively than CTAB?
