英文摘要	It is of great significance to explore and develop in-situ preparation strategies to improve the activity and service life of monolithic catalysts. In this work, the strategy of alternating anode and cathode electro-deposition was creatively proposed, a hierarchical monolithic catalyst that three-dimensional nickel foam with an open-pore structure at the bottom, structural flexible MnOx crystal in the middle layer, and vertically oriented small size NiCo2O4 spinel phase at the top was successfully prepared. Consequently, NiCo2O4-MnOx-NF-250 monolithic catalyst exhibits lowest T-90 of 196 degrees C, and T'(90) of 204 degrees C (after ultrasonic exfoliation experiment) at 6000 h(-1) gaseous hourly space velocity (GHSV) for 100 ppm benzene combustion. It has been convinced that a monolithic catalyst with high activity and strong anchoring force was successfully prepared by a simple strategy of alternating anode and cathode electro-deposition, which not only provides a strategy for designing monolithic catalyst but also paves the way for industrial benzene removal.
