Abstract
In this work, anodic aluminum oxide (AAO) over Al mesh was fabricated as a support for monolithic catalyst for ozone decomposition. AAO with the pore sizes of about 9–38 nm could be obtained by increasing the voltage from 20 to 40 V. A mechanism was proposed to address the formation of AAO over Al mesh. Different with the case over Al plate, the key of the formation of porous AAO over Al mesh is to seal the edges of the Al mesh immersed in the electrolyte to keep the conductivity of the interlaced Al wires. Mn–Co nanospheres with the size of about 80 nm were decorated on AAO through a simple dip-coating process. The obtained material then was used as monolithic catalyst for ozone decomposition. It was found out that the developed material showed much better activity than Mn–Co composite decorated on Al mesh only, which is possibly due to the combination of the adsorption ability of AAO and the catalytic property of Mn–Co composite.
