Enhanced High-Rate Capability of the C-N-Doped TiO2 as Anode Material for Lithium-Ion Battery

An Investigation of Interfacial and Photoelectrochemical Performance of Thermally Prepared C,N‐codoped TiO2 Photoanodes for Water Splitting

“…Lowering of the band gap values for the C,N‐codoped TiO 2 sample could be attributed to doping of non‐metals. The narrower band gap of TiO 2 could be found via the interstitial nitrogen doping which is consistent with N (1 s) spectrum of XPS analysis. The strong visible light absorption of the C,N‐codoped TiO 2 is mainly attributed to the hybridized 2 p states of N and C atoms .…”

High-rate lithium storage of anatase TiO2 crystals doped with both nitrogen and sulfur

“…So far, several anion dopants including C, N/C, and F have been introduced into TiO 2 with the main purpose of lowering electron transport resistance. [16][17][18] It is established that the effects of anion doping on modification of the electronic structure and thus electron transport are sensitive to the spatial distribution of dopants in doped substrates. 19,20 The homogeneous distribution of dopants throughout the whole particle rather than only in the surface layer is indispensable for fully modifying the electronic structure of the doped TiO 2 .…”

High rate capability of TiO2/nitrogen-doped graphene nanocomposite as an anode material for lithium–ion batteries

“…It is usually considered that the semicircle in the high frequency range is related to the charge transfer resistance [35,41]. The Nyquist plots show that the diameter of the semicircle for the TiO 2 /nitrogendoped graphene nanocomposite in the high-medium frequency region is smaller than those of the TiO 2 /graphene nanocomposite and the bare TiO 2 nanoparticles (Fig.…”
