英文摘要	Layered titania (L-TiO2) holds great potential for potassium-ion batteries (PIBs) and sodium-ion batteries (SIBs) due to their high specific capacity. Synthesizing L-TiO2 functional materials for high-capacity and long cyclability battery remains challenging due to the unstable and poor conductivity of bare L-TiO2. In nature, plant growth can stabilize land by preventing sands from dispersing following desertification. Inspired by nature's sand-fixation model, Al3+ seeds are in situ grown on layered Ti3C2Tx land. Subsequently, NH2-MIL-101(Al) plants with Al as metal nodes are grown on the Ti3C2Tx land by self-assembly. After annealing and etching processes (similar to desertification), NH2-MIL-101(Al) is transformed into interconnected N/O-doped carbon (MOF-NOC), which not only acts as a plant-like function to prevent the pulverization of L-TiO2 transformed from Ti3C2Tx but also improves the conductivity and stability of MOF-NOC@L-TiO2. Al species are selected as seeds to improve interfacial compatibility and form intimate interface heterojunction. Systematic ex situ analysis discloses that the ions storage mechanism can be endowed by mixed contribution of non-Faradaic and Faradaic capacitance. Consequently, the MOF-NOC@L-TiO2 electrodes exhibit high interfacial capacitive charge storage and outstanding cycling performance. The interface engineering strategy inspired by sand-fixation model provides a reference for designing stable layered composites.
