Abstract

•α-MnO2 mesoporous interlocked micro-cubes of several interconnected nanocrystals were successfully synthesized.•A cubic structure with the lattice fringe spacing of 0.24 nm for (1 1 0) plane has corroborated α-MnO2 phase.•α-MnO2 sensor has demonstrated 33% response at 100 ppm of NO2 gas, respectively 26 s and 91 s response and recovery time signatures, high selectivity, good sensitivity, and high stability at 150 °C.
