A hierarchically structured MnO_x-NiCo₂O₄ monolithic catalyst with rich phase interfaces was designed by a simple, eco-friendly and time-saving in-situ electro-deposition method. The abundance of active oxygen species due to this rich phase interfaces contributed to the excellent benzene combustion performance of MnO_x-NiCo₂O₄-2:2 sample, oxidizing about 90% of benzene (T₉₀) at 198 ℃ under 12000 h^-1 gaseous hourly space velocity. This work shed new light on the design of excellent monolithic catalysts, which might pave the way for the industrialization of benzene combustion.
