Researchers from the University of Perugia, Università Mediterranea di Reggio Calabria, and ENEA investigated new applications for end-of-life photovoltaic waste. The study focused on recovering silicon from discarded PV panels and using it as a heterogeneous support material. Recovered silicon was combined with palladium nanoparticles to create catalytic systems for Mizoroki–Heck cross-coupling reactions. The catalyst delivered strong activity, low palladium leaching, and repeat-use performance comparable with established Pd catalysts. Researchers prepared 20 products, including methyl (E)-ferulate and intermediates linked to pharmaceutical synthesis. The work addressed projected PV waste growth, which could reach 8 million tons globally by 2030.
