Persistent CO₂ Reduction Performance of an Ag Nanoparticle Gas Diffusion Electrode in Realistic Dynamic PV-Driven Operation.

ABSTRACT: Progress in the development of CO₂ reduction catalysts has revealed more stable and selective options for solar fuel production. In most cases, the catalysts are tested under steady-state conditions. However, to become a reliable long-term storage solution for renewable energy, particularly photovoltaics (PV), CO₂ electroreduction must tolerate power intermittency. Direct coupling of CO₂ electrolyzers to PV devices enables carbon utilization and efficient energy storage but requires catalysts that maintain consistent performance under dynamic power input. Herein, we select an Ag nanoparticle gas diffusion cathode with stable CO production across a wide current density range. The system, directly coupled to a hardware-emulated Si-PV module operating under a
