Abstract

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.
