Carbon aerogels are a fascinating three-dimensional (3D) monolithic porous material with remarkable physicochemical properties, including low density, large surface area, abundant pore structure, high electrical conductivity, chemical stability, environmental compatibility, adjustable surface chemistry, as well as controllable structural features. These properties endow carbon aerogels with excellent adsorption and catalytic performance. Therefore, they are widely applied in environmental chemistry for removing pollutants like oils, toxic organic solvents, dyes, heavy metal ions in aquatic environments, and vol- [a] Minireview Carbon aerogels show wonderful adsorption and catalytic performance because of the microscopic properties of carbon nanomaterials and the macroscopic structure of the gel.

“…The stochastic nature of the gelling process generates open voids of random shape and size with distribution modes usually located in the mesopore range (2–50 nm). Larger pores facilitate migration and diffusion of chemical species and allow even the passage of macromolecules . The augmentation of MOF channel sizes to the mesoporous range still poses a great challenge.…”

Metal‐organic gels (MOGs) appear as a blooming alternative to well‐known metal‐organic frameworks (MOFs). Porosity of MOGs has a microstructural origin and not strictly crystalline like in MOFs; therefore, gelation may provide porosity to any metal‐organic system, including those with interesting properties but without a porous crystalline structure. The easy and straightforward shaping of MOGs contrasts with the need of binders for MOFs. In this contribution, a series of MOGs based on the assembly of 1D‐coordination polymer nanofibers of formula [M(DTA)]n (MII: Ni, Cu, Pd; DTA: dithiooxamidato) are reported, in which properties such as porosity, chemical inertness, mechanical robustness, and stimuli‐responsive electrical conductivity are brought together. The strength of the MS bond confers an unusual chemical resistance, withstanding exposure to acids, alkalis, and mild oxidizing/reducing chemicals. Supercritical drying of MOGs provides ultralight metal‐organic aerogels (MOAs) with densities as low as 0.03 g cm−3 and plastic/brittle behavior depending on the nanofiber aspect ratio. Conductivity measurements reveal a semiconducting behavior (10−12 to 10−7 S cm−1 at 298 K) that can be improved by doping (10−5 S cm−1). Moreover, it must be stressed that conductivity of MOAs reversibly increases (up to 10−5 S cm−1) under the presence of acetic acid.

“…[1][2][3] Porous carbons have already been extensively applied in the elds of separation, purication, catalysts and catalyst supports, supercapacitors, electrochemical electrodes, sensors and thermal insulation. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Porous carbons can be prepared in the form of bers, membranes, capsules, powders and monoliths. 4 Among these porous carbons with different shapes, porous carbon monoliths are of vital importance because they have promising applications in elds involving catalyst carriers, thermal and acoustic insulation, adsorption of volatile organic pollutants in the air, hydrogen storage, and sewage disposal, where porous carbon monoliths are functionally advantageous.…”
