This paper presents the experimental investigation of copper loaded carbon nanotubes (CNTs) electrocatalysts for the\nelectrochemical reduction of carbon dioxide. The electrocatalysts were synthesized by homogeneous deposition precipitation\nmethod (HDP) using urea as precipitating agent. The prepared catalysts were characterized by TEM, SEM, XRD, XPS, BET, and\nFTIR for their morphology and structure. Characterization results confirm the deposition of Cu nanoparticles (3ââ?¬â??60 nm) on\nCNTs. Linear sweep voltammetry (LSV) and chronoamperometry (CA) were used to investigate the activity of the as-prepared\ncatalysts for the electrochemical reduction of carbon dioxide. The electrocatalysts reduced CO2 with high current density in\nthe potential range 0??3V versus SCE (standard calomel electrode). Among all catalysts tested, 20 wt. % copper loaded CNTs\nshowed maximum activity. Gas chromatograph with TCD was used to analyze liquid phase composition. The faradaic efficiency\nfor methanol formation was estimated to be 38.5%.
