Abstract
A series of interlaced 'tripe-shaped' nanoflake catalysts made of CuMn<sub>2</sub>O<sub>4</sub>were<i>in situ</i>prepared on Ti mesh substrate through the associated methods of plasma electrolyte oxidation and hydrothermal technique. The surface morphology, elemental distribution and chemical state, phase composition and microstructure of CuMn<sub>2</sub>O<sub>4</sub>nanostructures prepared under different conditions were systemically investigated. To evaluate the catalytic activity, the CO oxidation as a probe reaction was used, and the results showed that 12h-Cu1Mn2-300 (hydrothermal reaction at 150 °C for 12 h, Cu/Mn = 1/2 in initial precursor, heat treatment temperature at 300 °C) exhibited the best CO oxidation capability with<i>T</i><sub>100</sub>= 150 °C owe to the formation of uniform CuMn<sub>2</sub>O<sub>4</sub>nanosheet layers<i>in situ</i>grown on flexible Ti mesh and the synergistic effect of Cu and Mn species in spinel CuMn<sub>2</sub>O<sub>4</sub>, which makes it more active towards CO oxidation than pure copper/manganese oxides.
