The electrochemical reduction of carbon dioxide (CO2) is gaining attention as an effective method for converting CO2 into high-value carbon compounds. This paper reports a facile meth od for synth esizing and characterizing g-C3N4- modified porous Au (pAu) electrodes for electrochemical CO2 reduction using e-beam deposition and anodization techniques. The fabricated pAu@g-C3N4 electrode (@ -0.9 VRHE) demonstrated superior electrochemical performance compared to the pAu electrode. Both electrodes exhibited a Faradaic efficiency (FE) of 100% for CO production. The pAu@g-C3N4 electrode achieved a maximum CO production rate of 9.94 mg/s, which is up to 2.2 times higher than that of the pAu electrode. This study provides an economical and sustainable approach to addressing climate change caused by CO2 emissions and significantly contributes to the development of electrodes for electrochemical CO2 reduction.
