Ultrahigh selectivity and response to sub-ppm-level of <italic>p</italic>-xylene was achieved using CoCr<sub>2</sub>O<sub>4</sub>–Cr<sub>2</sub>O<sub>3</sub> spheres. The unique catalytic effect and nanoscale heterojunction of CoCr<sub>2</sub>O<sub>4</sub> and Cr<sub>2</sub>O<sub>3</sub> provide a strategy to design high performance volatile organic compounds sensors for monitoring air quality.
