• Resumen

  • The aim of this chapter is to provide an overview on synthetic approaches for the preparation of activated carbons with adequate porosity for the storage and separation of small gases of strategic interest (e.g., H2, CO2, and CH4). Nanoporous carbons are versatile materials that can exist in 3D architectures with high specific surface areas and pores of nanometric dimensions, which can be modulated by the choice of the precursor and the synthesis route. Even though numerous works exist on exploring approaches for the preparation of activated carbons with a controlled pore texture, we limit the discussion here to the control of the microporosity in carbons, since they exhibit the best performance in terms of gas storage, separation, and packing densities. We have summarized most relevant methodologies (covering conventional activations methods as well as new approaches) based on a rational material’s design to control the porosity, emphasizing on the preparation of microporous carbons.
