Abstract：

Cerium　metal-organic　frameworks　(Ce-MOFs)　have　attracted　extensive　attention　due　to　their　potential　in　photocatalytic　applications.　However,　Ce-MOFs　constructed　with　organic　carboxylic　acids　as　ligands　typically　exhibit　wide　band　gaps,　which　limit　their　utilization　in　the　visible-light　region.　This　work　proposes　a　strategy　to　design　visible-light-active　Ce-MOFs　by　employing　quinoline　sulfonic　acid　as　a　ligand.　The　synthesized　compound　(1-Ce)　features　a　high　surface　area,　open　Ce　metal　sites,　and　large-sized　1D　channels.　Benefiting　from　ligand-to-metal　charge　transfer,　1-Ce　demonstrates　good　visible　light　absorption.　Additionally,　the　chelating　coordination　of　nitrogen　and　oxygen　atoms　endows　1-Ce　with　excellent　chemical　stability.　Owing　to　its　abundant　metal　sites,　high　porosity,　and　visible　light　responsiveness,　1-Ce　exhibits　outstanding　photocatalytic　activity　for　CO2　reduction　under　visible　light,　achieving　a　CO　production　rate　of　138　μmol·g-1·h-1─surpassing　previously　reported　Ce-MOF　photocatalysts.　©　2025　American　Chemical　Society.
