Abstract

The increasing demand for energy, depletion of traditional energy sources, and environmental concerns have generated an energy crisis in recent years. To address this challenge, innovative and low-cost solutions have been sought, such as the use of 3D printing for decentralized hydrogen production. In this paper, we present the production of conductive filaments prepared from polylactic acid (PLA) and Carbon Black (CB), which were used for the 3D printing of electrodes. The produced materials were characterized by scanning electron microscopy, thermal analysis, and electrochemical techniques. The 3D-printed electrodes using the filaments prepared in the laboratory showed better electrochemical performance and hydrogen production compared to the electrodes printed with commercial filament. The PLA@CB72R and CoPi#PLA@CB72R electrodes showed better hydrogen production performance, 10.08 and 10.20 µmol min-1, respectively. This study provides a perspective for the manufacture of 3D printed filaments and electrodes for energy conversion applications, such as hydrogen production (AU)
