Redox cycles promoting photocatalytic hydrogen evolution of CeO2 nanorods

Oriented hexagonal CeO2 NRs were directly grown on Ti substrates via a simple template-free electrochemical method. These CeO2 NRs with {110} planes as the main exposed surfaces show significant photocatalytic activity for hydrogen evolution with Na2S-Na2SO3 as sacrificial agents due to their specia...

Zusammenfassung:	Oriented hexagonal CeO2 NRs were directly grown on Ti substrates via a simple template-free electrochemical method. These CeO2 NRs with {110} planes as the main exposed surfaces show significant photocatalytic activity for hydrogen evolution with Na2S-Na2SO3 as sacrificial agents due to their special redox capacity.
