This study reports a novel light-driven methodology for the sustainable synthesis of Pd-based nanocatalysts. The approach features operational simplicity, short reaction times, and environmental friendliness. The visible light-induced reduction of Pd2+ precursors, allowed for the efficient production of both colloidal and silica-supported palladium nanoparticles (Pd-NPs), stabilized with either polyvinylpyrrolidone (PVP) or carboxymethylcellulose (CMC). The method was successfully implemented in batch and continuous-flow systems, demonstrating excellent scalability and control over the nanoparticle size (
