Belt-like VO₂(B) single crystals unlock high-sensitivity gas detection at room temperature

An international research team has successfully synthesized oriented belt-shaped vanadium dioxide (VO2(B)) single crystals via a hydrothermal reduction method, using one-dimensional vanadium pentoxide (V2O5) nanofibers as the starting material. This work, published in the journal ACS Sensors, provides a new material platform and design guidelines for the development of next-generation low-power gas sensors capable of operating at room temperature.
