Abstract Developing and designing inexpensive, efficient, and low overpotential electrocatalytic CO2 reduction (ECR) catalysts is crucial for alleviating greenhouse effect and transforming carbon dioxide into treasure. In this study, the nickel phthalocyanine based molecular dispersion catalysts (NiPc/CNT) were fabricated through modification by different long-chain alkoxy groups and immobilized onto multi-walled carbon nanotubes (MWCNTs). The successful synthesis of NiPc/CNT was confirmed through comprehensive structural characterization, including infrared spectroscopy (IR), Raman spectroscopy (Raman), UV-Vis spectroscopy (UV-Vis), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Experimental results demonstrate that the NiPc-6/CNT exhibits high catalytic activity and excellent selectivity for ECR within the potential range of -0.70 V to -0.95 V, and the Faraday efficiency for CO production (FECO) approaches 100%. This study provides a novel molecular design strategy for the development of efficient electrochemical catalysts for ECR.
