Encapsulation of gases in powder solid matrices and their applications: A review

•We present current status of gas encapsulation in various powder solid matrices.•We describe molecular structure of solid matrices and gas adsorption mechanism.•The gas storage capacity of various solid matrices is compared.•Adsorption isotherm and release property of gases from matrices are described.•We discuss potential applications of resultant complexes in various fields.

Gas encapsulation in solid matrices can be an important means to sequester harmful or greenhouse gases and to store useful gases for their subsequent release for a targeted application. In this review, recent developments, the characteristics and gas adsorption capacity of non-organic and organic solid powder matrices (e.g. activated carbons, carbon nanotubes, zeolites, metal-organic frameworks, and cyclodextrins); and potential applications of their complexes in various fields (energy, environment protection, nano-device production, medicine, and food and agriculture productions) are described.
