This talk covers the fundamentals of bulk porous materials that are constructed from metal-oxides and organic molecules as well as from pure organic molecules. This field is so far developed that companies such as BASF® are producing these materials at the industrial level. In this activity we will learn how the design of the pores can help to trap and store the most gas. This is important because clean energy gases such as H₂ and CH₄ can be stored more efficiently. Also harmful gases such as NH₃ and CO₂ can be separated from contaminated mixtures. [RREP sponsors: Tenaris, Ternium, Techint]
