3D-Printed Conductive Polymers as Alternative for Bioelectrochemical Systems Electrodes: Abiotic Study and Biotic Start-Up

Applied Sciences, Journal Year: 2024, Volume and Issue: 14(16), P. 7199 - 7199

Despite over two decades of intense research into bioelectrochemical systems (BESs), their practical implementation remains unrealized, partly due to the low performance bioelectrodes. With introduction additive manufacturing techniques, development a new generation bioelectrodes with custom-shaped geometries using conductive composites has become feasible. This study examines potential composites, Poly-lactic acid (PLA) and thermoplastic polyurethane (TPU), for 3D-printed electrodes. Electrochemical characterization reveals that TPU charge transfer resistance approximately orders magnitude higher than PLA, rendering it unsuitable The presence triangular patterns enhances planar electrodes, optimal results observed PLA-based electrodes surface pattern depths between 0.6 1.4 mm. Additionally, electrodeposition (ED) graphene oxide (GO) further improves across all cases. During subsequent biotic start-up, patterned PLA depth mm exhibit current. However, these degradation after 56 days operation.

Development of efficient, low‐cost, robust, and structure tunability electrocatalysts for hydrogen evolution reaction (HER) is one the main subjects present study in renewable energies. In this work, two new cuprous iodide coordination polymers (Cu‐CPs) containing bisbenzimidazole‐derived ligand, namely, {[Cu 2 (L 1 )(μ ‐I) ]·DMF} n ( ) {[Cu(L 0.5 (μ ‐I)]·DMF} = (2,2′‐(1,3‐propanediyl)‐6,6′‐bis(3‐methylpyridine)bis‐1,3‐benzimidazole); L (2,2′‐(1,4‐butanediyl)‐7,7′‐bis(3‐methylpyridine)bis‐1,3‐benzimidazole); DMF dimethyl formamide), were prepared under solvothermal conditions structurally characterized. Single‐crystal structural analysis showed that although Cu‐CPs have a one‐dimensional (1D) chain backbone structure, environment different. It found different modes ligands lead to environments central ions CPs. Electrocatalytic HER modified electrodes (CP‐ ~ /glassy carbon electrode [GCE]) by coating mixed solution acetylene black, CPs – , Nafion on surface GCE was investigated M H SO 4 electrolyte. The measurements show overpotential η 10 293K CP‐ /GCE positively shifted 113 74 mV compared with bare (blank electrode, −930 mV), Tafel slope bare/GCE 298, 101, 138 dec −1 respectively. results indicate could effectively catalyze accelerate behavior, electrocatalytic activity order being > bare/GCE. higher can be attributed deformability ion CP greater. Furthermore, recognition performance glucose further studied chronoamperometry 0.1 NaOH. sensors detect linear range from μM mM sensitivities 13.736 18.945 μA also revealed long‐term stability good selectivity. These deserve investigation as potential electrocatalyst candidates.
