High-performance ceria via supramolecular metal–organic gel precursors for visible-light-driven hydrogen evolution from aqueous glucose

Abstract

A supramolecular cerium-based metal–organic gel (MOG) was used as a soft precursor to prepare a defect-rich CeO₂ photocatalyst. The resulting material exhibited enhanced visible-light-driven hydrogen evolution from glucose, outperforming conventionally synthesized ceria. Spectroscopic analysis revealed higher oxygen vacancy content and improved charge separation, highlighting the potential of MOG-derived photocatalysts.
