A facile bottom‐up synthesis approach is developed to prepare porous metal‐oxide ultrathin sheets, e.g., SnO 2 , Fe 2 O 3 , and SnO 2 ‐Fe 2 O 3 , with thicknesses of ∼5 nm. Graphene sheets are used as the sacrificing template. Such a process can be extended to the synthesis of multiphased porous metal‐oxide thin sheets. These porous thin sheets show interesting applications as gas sensors, effective platforms for matrix‐assisted laser desorption/ionization–time‐of‐flight mass spectrometry, and supercapacitors.
