Porous TiO2–FeTiO3@Carbon nanocomposites as anode for high-performance lithium-ion batteries

Novel Construction of Heterostructured FeTiO3/Fe2.75Ti0.25O4 Mesoporous Nanodisks with Both High Capacity and Stable Cycling Life for Lithium-Ion Storage

“…Furthermore, the Fe–Ti–O:1 electrode could exhibit a capacity of 478 mA h g –1 at a high rate of 1 A g –1 after 600 cycles, with 94.3% capacity retention. The cycling stability of the designed mesoporous FeTiO 3 /Fe 2.75 Ti 0.25 O 4 composite is also better than that of other MTiO 3 -based composites (Figure b), such as TiO 2 –Fe 2 O 3 @C, FeTiO 3 /Fe/C, TiO 2 –Fe 3 O 4 –FeTiO 3 , NiTiO 3 @G, and CoTiO 3 @G. ,,,− Our Fe–Ti–O:1 electrode exhibits relatively high capacity retention with long cycle life at high current density.…”

“…Transition metal titanates (TMTs) with combined advantages of TiO 2 and transition metal oxides have aroused the attention of researchers nowadays. − Ilmenite (FeTiO 3 ) with a theoretical capacity of 530 mA h g –1 is the most common member of TMTs for energy storage on account of its abundant reserve and ABO 3 -type structure with approximately equal sizes of Ti and Fe ions. , FeTiO 3 nanoflowers, FeTiO 3 /CNTs, FeTiO 3 /Fe/C, and TiO 2 –FeTiO 3 @carbon nanocomposites have been reported for LIBs, delivering over 400 mA h g –1 at low current densities. Unfortunately, the theoretical capacity of FeTiO 3 is not high enough on account of the low content of the Fe ion.…”

“…On the other hand, Fe–Ti–O compounds suffer from the low electronic conductivity and agglomeration during charge/discharge processes, resulting in moderate reaction kinetics and rapid capacity decay especially at high current densities. , To solve these bottlenecks, a nanostructure strategy aiming at shortening the Li + -ion diffusion path and alleviating volume expansion should be carried out. Metal–organic frameworks (MOFs) with chemical adjustability and tunable porosities have been found to be ideal precursors for synthesizing porous metal oxides for energy storage. − In addition, the large surface areas of MOF-derived composites could provide extra capacitive capacities.…”

Highly graphited carbon-coated FeTiO3 nanosheets in situ derived from MXene: an efficient bifunctional catalyst for Zn–air batteries

“…[19][20][21][22] Among the titaniumbased perovskite-type oxides, FeTiO 3 stands out due to its low price, abundant reserve, wide band gap and high activity, [23][24][25] however, it suffers from poor conductivity. 26 To solve this problem, FeTiO 3 is often compounded with highly conductive materials, such as recently reported FeTiO 3 @C nanoparticles, 27 porous TiO 2 -FeTiO 3 @carbon nanocomposites, 28 etc. Although these hybridizing methods can improve the conductivity of FeTiO 3 to some extent, the problems of low graphitization and uneven dispersion of carbon always exist.…”

FeTiO3 Perovskite Nanoparticles for Efficient Electrochemical Water Splitting

“…The recent advancement in ILs is desirable for the synthesis of nanomaterials with unique morphology via the solvothermal method [18]. Iron-based titanium oxides with formulating Z-scheme heterostructures of anodes have received great importance due to their strong electronic, magnetic and catalytic behaviors [19,20]. Moreover, the FeTiO 3 group of the crystalline structure is similar to corundum (Al 2 O 3 ), which has trigonal symmetry and an R3 ilmenite crystal structure.…”
