【 摘 要 】

tsRoom temperature graphene oxide-assisted assembly of 3D Ti3C2Tx MXene aerogels have been realized by introducing interfacial mediators (amino-propyltriethoxysilane, Mn2+, Fe2+, Zn2+, and Co2+).The methodology not only suppresses the oxidation degradation of Ti3C2Tx, but also generates porous aerogels with a high Ti3C2Tx content (87 wt%) and robustness.As freestanding electrode of the as-prepared Ti3C2Tx-based aerogel with a practical-level mass loading of 12.3 mg cm-2 still delivers an areal capacity of 1.26 mAh cm-2 at a current density of 0.1 A g-1.
