The　utilization　of　solar　energy　for　CO2　conversion　to　produce　valuable　chemicals　or　fuels　is　extremely　appealing　since　it　can　simultaneously　reduce　the　greenhouse　effect　and　relieve　the　energy　shortage　pressure.　In　addition　to　the　commonly　used　semiconductor-based　photocatalysts,　metal-organic　frameworks　(MOFs),　a　class　of　micro-mesoporous　hybrid　materials,　are　recently　emerging　as　new　types　of　photoactive　materials　for　CO2　reduction　due　to　their　excellent　adsorption　capability　toward　CO2　and　unique　structural　characteristics.　In　this　review,　we　summarized　the　recent　applications　of　MOFs　for　photocatalytic　CO2　reduction,　in　which　MOFs　either　act　directly　as　the　photocatalysts　for　CO2　reduction　or　as　components　in　a　hybrid　photocatalytic　system　to　promote　CO2　reduction.　This　review　starts　with　a　brief　introduction　of　the　background　of　photocatalytic　CO2　reduction,　followed　by　a　summarization　of　CO2　reduction　catalyzed　by　photoactive　ligands　and　metal　nodes　in　MOFs,　respectively.　Thereafter,　the　construction　of　hybrid　photocatalytic　systems　in　which　MOFs　play　a　role　in　promoting　photocatalytic　CO2　reduction　is　described.　Finally,　the　limitations,　challenges　and　future　prospects　of　the　application　of　MOFs　to　CO2　reduction　are　addressed.　We　hope　that　this　review　not　only　can　serve　as　a　starting　point　to　get　into　this　largely　unexplored　field　but　can　also　stimulate　intensive　research　on　the　rational　design　and　development　of　more　creative　MOF　systems　for　light　induced　CO2　conversion,　which　is　a　green　and　sustainable　strategy　for　CO2　utilization.　©　2017　The　Royal　Society　of　Chemistry.
