Efficient　removal　of　organic　pollutants　from　wastewater　has　become　a　hot　research　topic　due　to　its　ecological　and　environmental　importance.　Traditional　water　treatment　methods　such　as　adsorption,　coagulation,　and　membrane　separation　suffer　from　high　operating　costs,　and　even　generate　secondary　pollutants.　Photocatalysis　on　semiconductor　catalysts　(TiO2,　ZnO,　Fe2O3,　CdS,　GaP,　and　ZnS)　has　demonstrated　efficiency　in　degrading　a　wide　range　of　organic　pollutants　into　biodegradable　or　less　toxic　organic　compounds,　as　well　as　inorganic　CO2,　H2O,　NO3-,　PO43-,　and　halide　ions.　However,　the　difficult　post-separation,　easy　agglomeration,　and　low　solar　energy　conversion　efficiency　of　these　inorganic　catalysts　limit　their　large　scale　applications.　Exploitation　of　new　catalysts　has　been　attracting　great　attention　in　the　related　research　communities.　In　the　past　two　decades,　a　class　of　newly-developed　inorganic-organic　hybrid　porous　materials,　namely　metal-organic　frameworks　(MOFs)　has　generated　rapid　development　due　to　their　versatile　applications　such　as　in　catalysis　and　separation.　Recent　research　has　showed　that　these　materials,　acting　as　catalysts,　are　quite　effective　in　the　photocatalytic　degradation　of　organic　pollutants.　This　review　highlights　research　progress　in　the　application　of　MOFs　in　this　area.　The　reported　examples　are　collected　and　analyzed;　and　the　reaction　mechanism,　the　influence　of　various　factors　on　the　catalytic　performance,　the　involved　challenges,　and　the　prospect　are　discussed　and　estimated.　It　is　clear　that　MOFs　have　a　bright　future　in　photocatalysis　for　pollutant　degradation.
