abstract The world energy demands have been increasing in the last decades driven by strong economic growth and expanding populations. Alternative energy resources have been proposed to satisfy part of the energy needs. Biogas is an alternative energy source produced through the anaerobic digestion process of organic matter. Conventional and commercial processes used to purify biogas are presented and compared. Furthermore, the drawbacks associated with commercial technologies are exhibited, and the need to course in new directions is demonstrated. Alternative chemical adsorption technologies are displayed, and in addition, the challenge to turn the organic–inorganic hybrid materials selective for CO2/CH4 separation is introduced. The influence of the nature of the interfaces of different types of materials on CO2/CH4 separation is discussed, combining chemical, textural, and physical characterization and also experimental and computational adsorption studies. Comparative tables summarizing the adsorbents performances are presented. Special emphasis is given to materials reported in the last decade belonging to the families of (i) modified carbons, (ii) metal–organic frameworks, (iii) modified silicas, and (iv) periodic mesoporous organosilicas.
