Web1 de mar. de 2024 · The kinetic coupling of electron transfer and long-lived charge separation (∼ 4896 ps) are systematically investigated by femtosecond time-resolved absorption spectroscopy (fs-TA). The TA signal of the composite is quenched by hole sacrificial agent, assigning to the effective hole extraction for high photocatalytic activity.

WebHere we report exceedingly long-lived (up to a few hours) photoinduced charge separation in an artificial photosynthetic system that does not require a secondary substrate
WebWe find that the charge separation lifetime following ultrafast CT is remarkably long-lived, beyond 1 ns (limited by the scan range of the setup). This observation is in sharp contrast to the short-lived excited-state dynamics (~1 ps) in WS 2 observed by TA, both in this study and in previous works ( 10 , 11 ).
