Ultrathin single‐crystalline V 2 O 5 · 0.76H 2 O nanosheets with a thickness of 1.5–2.6 nm are prepared on the basis of molecular‐level ‘oriented attachment’ through special sol–gel chemistry. The initial formation of 3–7 nm nanodiscs by confining the condensation reactions within the ab plane is critical to form nanosheets. As a proof‐of‐concept, these nanosheets exhibit good properties for hydrogen sensors and supercapacitors.
