Enhanced Gas Adsorption in HKUST-1@Chitosan Aerogels, Cryogels, and Xerogels: An Evaluation Study

Renewable biomass-based aerogels: from structural design to functional regulation

“…For the latter, the multiple exposed hydroxyl groups along the cellulose molecular chain allow the grafting of functional groups like N -(2-aminoethyl)-3-aminopropylmethyldimethoxysilane (APMDS) to capture CO 2 (Table 4). 175–185…”

“…First, increasing the amine content via chemical grafting or physical coating is pursued to elevate the number of CO 2 -binding active sites. 173,179 Second, augmenting the porosity and adjusting the pore structure of the aerogel aims to enhance the ability of the aerogel to accommodate CO 2 . 181,182 In this context, several effective BAs had been developed for CO 2 absorption, including CS–GO composite aerogels, 173 CS-alginate carbon spheres, 178 chitin-derived nitrogen-doped carbon, amine-modified CNF aerogels, 180 composite aerogels of MOF with biomass-based feedstock, 184 and more (Table 4).…”

Green synthesis of MOF-based textile composites for the degradation of a chemical warfare agent simulant

“…Indeed, these functions must interact by metal–chitosan coordination (H 2 N → Zr and HO → Zr), as previously observed with HKUST-1@chitosan aerogels. 9…”

“…Indeed, these functions must interact by metal-chitosan coordination (H 2 N → Zr and HO → Zr), as previously observed with HKUST-1@chitosan aerogels. 9 Finally, the preparation method has been developed without using toxic solvents and heating steps. The principal aim of using these synthetic conditions is to prove the efficiency of a green composite against chemical hazards.…”

Chemical shaping of CPO-27-M (M = Co, Ni) through an in situ crystallization within chitosan hydrogels

“…The initial weight loss up to 120 °C is likely due to the removal of residual solvents such as methanol, water, and DMF. The second weight loss step, starting at 290 °C, is attributed to the beginning of chitosan degradation, 20 and the collapse of the MOF structure as a result of the combustion of the organic linker and the formation of cobalt oxide( ii , iii ). 21 The final weight loss corresponds to the reduction of Co 3 O 4 to CoO at approximately 900 °C.…”
