The book Porous Materials for Carbon Dioxide Capture is aimed at providing researchers with the most pertinent and up-to-date advances related to the fields of porous materials design and fabrication and subsequent evaluation in innovative cyclic CO2 adsorption processes, with special emphasis on uncovering the relationships between structural characteristics and CO2 capture performance. The book is divided into seven chapters that provide a resume of the current state of knowledge of porous CO2 capture materials, which include ionic liquid-derived carbonaceous adsorbents, porous carbons, metal-organic frameworks, porous aromatic frameworks, microporous organic polymers, sorption techniques such as cyclic calcination and carbonation reactions, and membrane separations. 

The same Lewis acid-catalyzed reaction of the cyanosilylation of aromatic aldehydes was investigated by Long et al. [85]. The catalytic activity of the sodalite-type compound Mn3[Mn Cl3(btt)g(CH30H),Q] (BTT is l,3,5-benzene-tris(tetrazol-5-yl)) was studied. This material is a 3D porous structure with a pore diameter of 1 nm. It was assumed that each of the two types of Mn(II) sites exhibits catalytic activity. The distinctive features of this catalyst are the high conversions in the case of small substrates and a good substrate size selectivity, properties that are consistent with the occurrence of the catalytic process in the channels. The surface of the framework bears open Mtf+ ions, which act as Lewis acid sites.
