Single‐crystal α‐Mn 2 O 3 nanowires were prepared via a “self‐sacrificing template” route, simply by calcining the prepared α‐MnO 2 nanowire precursors at 550 °C for 1.5 h. XRD, TEM, SEM and HRTEM characterizations show that the as‐prepared α‐Mn 2 O 3 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‐Mn 2 O 3 nanowires were studied in the degradation of coking wastewater with H 2 O 2 as the oxidant, and the technological conditions were optimized by single‐factor and orthogonal experiments.
