Abstract Composite materials integrating precious metals (Au, Ag, Pd, Pt, Ru, Rh, Ir) with CeO 2 , a rare earth metal oxide, are increasingly utilized in photocatalytic CO reduction. notable for its redox characteristics, oxygen storage capacity (OSC), and abundant vacancies (O v ), emerges as key player semiconductor catalyst research. The selection of their application techniques crucial modifying ′s wide bandgap enhancing light absorption, thereby influencing the efficiency. Approaches incorporating onto include single atoms, clusters, nanoparticles. This review provides an in‐depth analysis progress composite photocatalysts comprising It examines diverse modification strategies, such particle size adjustment heterojunction formation. concisely elucidates principles behind converting into high‐value products (hydrocarbons, C1, C2, C2+). Lastly, it addresses challenges future directions metal‐CeO catalysts
