The present invention provides a method for adsorbing carbon dioxide onto porous metal-organic framework materials, a method for cooling porous metal-organic framework materials, a method for obtaining aldehyde using porous metal-organic framework materials and a method for warming porous metal-organic framework materials. In each method, porous metal-organic framework materials are used while an electric field or an electromagnetic field is applied to the porous metal-organic framework materials, or while a magnetic field or an electromagnetic field is applied to the porous metal-organic framework materials. If an electric field is applied, at least one organic compound included in the porous metal-organic framework materials is a polar compound. Instead, if a magnetic field is applied, at least one metal included in the porous metal-organic framework materials has an unpaired electron. |
