This paper focuses on enhancing the performance of electrocatalytic CO reduction reaction (CORR) by improving the dispersion of cobalt phthalocyanine (CoPc), especially for the methanol formation with multi-walled carbon nanotubes (CNTs) as a support. The promising CNTs-supported CoPc hybrid was prepared based on ball milling technique, and the surface morphology was characterized by means of those methods such as scanning electron microscopy (SEM), Fourier transform infrared spectrometer (FT-IR) and X-ray photoelectron spectra (XPS). Then, the synergistic effect of CNTs and ball milling on CORR performance was analyzed by those methods of cyclic voltammetry (CV), linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS), gas chromatography (GC), and proton nuclear magnetic resonance spectroscopy (HNMR).

- * Characterization techniques like SEM, BET, and various thermal analyses were used to show that the adsorbent has a high CO adsorption capacity of 4.2 mmol/g at low temperatures.
- * The study found that the pore structure develops through a series of chemical reactions, particularly during the later stages of activation, indicating that the findings could help design better materials for gas adsorption applications.
