Özet

This study investigates integration of green-synthesized nanocatalysts with 3D-printable material and use the resulting structures as electrocatalysts (NiMo@Ag-PLA electrode) in a photovoltaic-supported alkaline electrolysis system. Honeycomb-structured cathodes were created by fused deposition modeling (FDM), green-synthesized NiMo@Ag nanoparticles embedded to improve electrochemical activity. The characterization and surface monitoring were performed using UV-VIS, FTIR, Zeta potential analysis, AFM, XRD, FE-SEM-EDX, TEM and contact angle measurements, that confirmed the formation of core–shell structure with uniform dispersion in PLA matrix. Electrochemical tests revealed that the hydrogen evolution reaction (HER) performance was enhanced by lowering the onset potential to −255 mV vs. Ag/AgCl, increasing the current density by nearly ninefold at −2.0 V vs. Ag/AgCl compared to PLA, and reducing the charge transfer resistance by approximately twenty-fivefold relative to PLA. These findings show the potentiality of combining green-synthesized nanomaterials with 3D printing and solar energy to develop efficient systems for sustainable hydrogen production.
