Gelatin-modified Mxene carbon aerogels for ammonium-perchlorate-catalyzed thermal decomposition

The assembly of 2D Ti₃C₂T nanosheets into 3D structures with orderable structure has great importance for their use as catalyst carriers. However, Ti₃C₂T nanosheets are prone to accumulate in aqueous solutions owing to the strong van der Waals forces between Ti₃C₂T nanosheet layers, degrading their chemical properties. Carbon aerogel (Ti₃C₂T/G/Co) with a 3D porous structure and cobalt as the active site was prepared by a simple co-assembly-freeze-drying-high-temperature carbonization method for application in catalysis of ammonium perchlorate.
