Synthesis of Co-Mn Oxides with Double-Shelled Nanocages for Low-temperature Toluene Combustion

Abstract

In this paper, we report a template-engaged strategy for the synthesis of Co-Mn composition oxides with double-shell box-in-box hollow nanocages (BHNCs) structure. The inner shell of the box is made of Co3O4, while the outer shell Co-Mn composition oxides. The composition of the outer shell was tuned by changing the Mn/Co molar ratio. This facile method can be used to construct box-in-box hollow structures of other transition metal composition oxides such as those of Co-Ni, Co-Cu and Co-Fe. These Co-Mn oxides with BHNCs exhibit toluene conversion over 90% at 250 °C, much higher than those of Co3O4 nanocages (NCs) and the traditional one at the same temperature. Moreover, the former is superior to the latter in terms of resistance towards H2O and CO2. The superior catalytic performances of Co1Mn1 BHNCs is attributed to high mobility of lattice oxygen, low toluene desorption temperature and active Co3+ sites originated in the oxidation of Co2+ by Mn3+.
