Graphene-based　sheets　which　possess　a　unique　nanostructure　and　properties　have　been　appealing　as　promising　nanoscale　building　blocks　of　film　materials.　Herein,　graphene-based　sheets　have　been　not　only　used　as　support　templates　to　fabricate　graphene-particle　composite　films,　but　also　as　effective　sacrificial　templates　to　prepare　freestanding　particle　films.　Freestanding　metal　oxide　particle　(Fe2O3　and　TiO2)　films　are　obtained　by　synthesis　of　graphene　oxide-particle　precursor　composites,　assembling　these　composite　sheets　into　freestanding　films　by　vacuum　filtration　and　the　subsequent　calcination　in　air.　Moreover,　the　thickness　and　certain　properties　of　these　as-prepared　particle　films　can　be　facilely　controlled　by　adjusting　the　amount　of　the　original　graphene　oxide-particle　composites.
