A simple one‐step solvothermal synthetic approach has been applied to the rapid fabrication of VO x nanoscrolls (NScs) from vanadium pentoxide and either dodecylamine or octadecylamine as the structure‐directing agent (SDA). By reaction of the appropriate ratio of SDA to vanadium oxide and solvent at 250 °C, approximately 20 g of NScs per synthesis could be formed within 2 h. Syntheses could be further adjusted so that the average lengths of the NScs could be varied from approximately 383 to 816 nm to 3.3 μm. The effect of synthesis parameters such as temperature, solvothermal reaction duration, and vanadium oxidation state on the formation of NScs was also investigated; detailed studies indicate that the variation between V 4+ and V 5+ appears to play a critical role in the formation of vanadate NScs.
