Highly selective photoelectrochemical CO₂ reduction by crystal phase-modulated nanocrystals without parasitic absorption.

ABSTRACT: Photoelectrochemical (PEC) carbon dioxide (CO₂) reduction (CO₂R) holds the potential to reduce the costs of solar fuel production by integrating CO₂ utilization and light harvesting within one integrated device. However, the CO₂R selectivity on the photocathode is limited by the lack of catalytic active sites and competition with the hydrogen evolution reaction. On the other hand, serious parasitic light absorption occurs on the front-side-illuminated photocathode due to the poor light transmittance of CO₂R cocatalyst films, resulting in extremely low photocurrent density at the CO₂R equilibrium potential. This paper describes the design and fabrication of a photocathode consisting of crystal phase-modulated Ag nanocrystal c
