Advances of Metal‐Organic Frameworks in Energy and Environmental Applications

Nowadays, energy shortage and environmental pollution issues are increasingly severe and urgent to be solved. The effective storage and use of environmentally friendly fuels and removal of harmful gases from the environment are great challenges and of great importance both for the environment protection and for human health. Porous metal‐organic frameworks (MOFs) are highly ordered crystalline materials formed by the self‐assembly process of metal ions and organic ligands. Their good features such as ultrahigh porosity, large surface area, structural diversity and functionalities make them promising candidates for applications in energy and environmental fields. MOF thin films and MOF composites have also been investigated to further enhance the properties and introduce new functionalities. This review provides an overview of the synthesis methods of pristine MOFs, MOF thin films and MOF composites, and significant advances of MOFs in energy and environment applications such as energy storage (H2, CH4), CO2 capture and separation, adsorption removal and sensing of harmful gases in the environment. Metal‐organic frameworks (MOFs) have aroused great attention over decades owing to their features such as ultrahigh porosity, large surface area, structural diversity and functionalities which make them promising candidates for diversified applications. This microreview focuses the emphasize on their applications in energy and environmental fields such as energy storage (H2 and CH4), CO2 capture and separation, adsorption removal and sensing of harmful gases in the environment, and also depicts some challenges and perspectives.
