Abstract

original image

Lichtgetrieben: Wasserlösliche Poly(acrylsäure)-Katalysatoren PAA-g-Fe2S2 mit biomimetischen {Fe2S2}-Zentren wurden hergestellt. Zusammen mit CdSe-Quantenpunkten (CdSe-QDs) und Ascorbinsäure zeigen sie außergewöhnliche Turnoverzahlen (TON) und -frequenzen (TOF) von 27 135 bzw. 3.6 s−1 für die photokatalytische Bildung von H2 in Wasser; dies ist die bisher höchste Effizienz für [FeFe]-Hydrogenasemimetika.
