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