Plasma modulated MOF-derived TiO2/C for enhanced lithium storage

A Novel Hybrid Point Defect of Oxygen Vacancy and Phosphorus Doping in TiO2 Anode for High-Performance Sodium Ion Capacitor

“…The TiO 2 /C was firstly obtained using a Ti-MOF precursor according to references [ 17 , 33 ] through pyrolysis at 600 °C under Ar for 2 h with a heating rate of 2 °C min −1 . Then, the oxygen vacancies (OVs) containing TiO 2 /C samples were obtained in Ar/H 2 gas at 500 °C for 1, 2, 3, 4, and 5 h, and named as TiO 2 /C-O1, TiO 2 /C-O2, TiO 2 /C-O3, TiO 2 /C-O4, and TiO 2 /C-O5, respectively.…”

“…Point defects engineering (vacancies and heteroatoms doping) in compounds is a popular way to modulate their electronic structure and chemical properties due to the lattice distortion and electron redistribution [16]. For instance, the introduction of oxygen vacancies (OVs) into TiO 2 can reduce the energy band gap and increase the density of states (DOS), thereby enhancing their electrical conductivity and kinetic [17][18][19]. In addition, surface functionalization of TiO 2 by phosphating can stimulate high chemical reaction activity, improve ion diffusion dynamics and electrical conductivity to achieve fast and efficient charge transfer, resulting in better electrochemical performance [20][21][22].…”

Metal–organic framework based electrode materials for lithium-ion batteries: a review

“… 178 Wang and co-workers prepared a TiO 2 /C composite by two-step calcination of Ti-MIL-125. 179,180 The two-step calcination enables the development of sub-micrometer tablet-type structures of a titania oxide–carbon composite which presented a highly reversible capacity of 1000 mA h g −1 and greater rate capability.…”

A metal–organic framework approach to engineer mesoporous ZnMnO3/C towards enhanced lithium storage

“…A variety of single metal oxides derived from MOF sources, such as TiO 2 /C, a-Fe 2 O 3 and M-Fe 2 O 3 , have been continuously fabricated and investigated for energy storage applications. 18,19 Probably due to the effective combination of structures and functionalities, some kinds of polymetallic MOF-derived TMOs, such as ZnCo 2 O 4 /C, Ni/ CoFe 2 O 4 @C and Zn 0.697 Mn 0.303 Se/C, are generally recognized to enhance the activity of electrochemical reactions. 20,21 Only a few studies focussed on multi-component TMOs, such as NiCo 2 O 4 , CuCo 2 O 4 and Co 2 VO 4 , which have been investigated and used as LIB anodes.…”
