Two-dimensional catalytic materials derived from metal-organic frameworks for VOC remediation

A metal oxide catalyst formulation including a porous metal oxide catalyst for oxidizing volatile organic compounds (VOCs) prepared by a method comprising:

• (a) preparing a metal-organic framework (MOF) material;
• and
• (b) decomposing the MOF material by heating the MOF material to a temperature of above 200° C. to below 500° C. to produce a porous metal oxide catalyst useful for removing one or more VOCs from an atmosphere or environment,
• wherein the MOF is prepared from a combination of metal ions, ligands, and one or more selected from the group consisting of solvents, water, and ionic liquids,
• wherein the porous metal oxide catalyst has planar or two-dimensional morphologies, and
• a surface area of 117.3 m2 g−1 and a pore diameter of 8.6 nm, and
• wherein the porous metal oxide catalyst consists of ceria.
