Abstract: | Single‐crystal α‐Mn2O3 nanowires were prepared via a “self‐sacrificing template” route, simply by calcining the prepared α‐MnO2 nanowire precursors at 550 °C for 1.5 h. XRD, TEM, SEM and HRTEM characterizations show that the as‐prepared α‐Mn2O3 samples are all phase pure and the nanowires have uniform diameters of approximately 15‐30 nm and lengths up to several micrometers. The catalytic performances of the prepared α‐Mn2O3 nanowires were studied in the degradation of coking wastewater with H2O2 as the oxidant, and the technological conditions were optimized by single‐factor and orthogonal experiments.
