摘要

In article number 1900111, Linfeng Hu and co‐workers find that layered acid niobium phosphate (2NbOPO4·H3PO4·H2O) can be well crystallized into a two‐dimensional morphology with a typical layered crystal structure in a mild oxalic acid system. Unilamellar nanosheets are manufactured by a liquid‐exfoliation strategy from the bulk 2NbOPO4·H3PO4·H2O. This novel compound exhibits a wide potential window of 0–1.0 V in aqueous electrolyte (vs Ag/AgCl electrode) with a proton‐intercalation mechanism.
