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 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.
