Italian researchers have developed a Pd/Si catalyst for upcycling silicon from end-of-life PV panels, achieving performance comparable to commercial catalysts over six cycles. The system involves palladium nanoparticles supported on recovered silicon, allowing for stable recycling. The method aims to manage the increasing global waste of EoL solar panels and expand the use of silicon in various catalytic processes. The process involves removing the front glass of discarded PV modules, purifying the silicon cells, and preparing the Pd/Si catalyst. The catalyst showed promising results in a benchmark reaction, indicating its potential as a sustainable and efficient catalyst for various applications. Researchers have developed a new recycling process using a Pd/Si catalyst to upcycle silicon from End-of-Life photovoltaic panels for the Mizoroki-Heck cross-coupling reaction. The catalyst was used in five recycling cycles with a 97% isolated yield and an E-factor of 9. The process was successful in synthesizing 22 substrates from various iodoarenes and olefins, including intermediates for important compounds. The study was published in Green Chemistry and involved researchers from Italy's Mediterranea University of Reggio Calabria, University of Perugia, and the Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA).
