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

The assembly of 2D Ti 3 C 2 T x nanosheets into 3D structures with orderable structure has great importance for their use as catalyst carriers. However, Ti 3 C 2 T x nanosheets are prone to accumulate in aqueous solutions owing to the strong van der Waals forces between Ti 3 C 2 T x nanosheet layers, degrading their chemical properties. Carbon aerogel (Ti 3 C 2 T x /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.
