Abstract: Porous metal oxide catalytic materials with planar morphologies which are derived from metal-organic framework (MOF) materials via thermal decomposition, oxidation pretreatment and pyrolysis processes. The porous metal oxides are mainly transition metal oxides, derived from MOFs containing the corresponding transition metal ions, such as Cu, Zn, Y, La, Ce, Ti, Zr, V, Cr, Mn, Fe, Co, and Ni ions. The transformation conditions from MOF materials to metal oxides, such as temperature, atmosphere and duration, are well defined to obtain metal oxides with controlled morphologies. Furthermore, the present subject matter relates to a low-temperature catalytic decomposition of volatile organic compounds (VOCs) with a wide concentration range on two-dimensional metal oxides.
