WebFeb 1, 2024 · The polymer photocatalyst was dispersed in 50 mL reaction solution of Et 3 N/MeOH/H 2 O (1:1:3, v:v:v) by ultrasonicating for 1 h before the photocatalytic measurement. The polymer PF6-SF with alkyl side chains shows poor dispersity in the working solution. WebLinear conjugated polymers have potential as photocatalysts for hydrogen production from water but so far, ... Here, we show that a conjugated polymer photocatalyst for proton reduction can be coupled in a Z-scheme with an inorganic water oxidation photocatalyst to promote overall water splitting without any sacrificial reagents.
