Hydrogen　peroxide　(H2O2)　is　a　versatile　compound　with　widespread　applications　in　various　industries.　In　addition,　it　has　attracted　interest　as　a　potential　energy　carrier　due　to　its　high　energy　density　and　ability　to　release　oxygen　upon　decomposition.　The　development　of　photocatalytic　technology　has　enabled　sustainable　production　of　H2O2.　Various　structural　materials,　including　organic　molecules,　polymers,　and　metal　coordination　compounds,　have　been　synthesized　for　investigating　photocatalytic　H2O2　production.　Rare　earth　materials,　in　particular,　are　of　interest　due　to　their　adjustable　porosity　and　controllable　metal　active　sites,　making　them　valuable　for　research　in　this　field.　These　materials　have　excellent　photoelectric　properties,　making　them　promise　for　the　photocatalytic　synthesis　of　H2O2.　Despite　limited　reports　on　systematic　reviews　of　photocatalytic　H2O2　production　using　rare　earth　materials,　this　study　introduces　the　principles　and　advancements　in　this　area.　It　reviews　different　methods　of　photocatalytic　synthesis　of　H2O2,　focusing　on　rare　earth　elements.　Through　comprehensive　analysis　and　systematic　studies　in　the　existing　literature,　a　deeper　understanding　of　enhanced　photocatalytic　performance　has　been　achieved.　This　research　not　only　contributes　to　advancing　fundamental　knowledge　but　also　provides　a　solid　foundation　for　practical　applications.　©　2024　Chinese　Society　of　Rare　Earths
