Applications of TiO 2 nanomaterials in photocatalysis, batteries, supercapacitors and solar cells, have seen widespread development in recent decades. Nowadays, black TiO 2 have won attention due to enhancing the solar light absorption by the formation of oxygen vacancies and Ti 3+ defects, to promote the separation of photo-generated charge carriers leading to the improvement of the photocatalytic performance in H 2 production and pollutants degradation. The enhanced photocatalytic activity of black TiO 2 is also due to a lattice disorder on the surface and the presence of oxygen vacancies, Ti 3+ ions, Ti-OH and Ti-H groups. Enhancing the optical absorption characteristics of TiO 2 and change of energy level and band-gap of materials have been successfully demonstrated to improve their photocatalytic activities, especially for black TiO 2 nanoparticles, which promote visible light absorption. The current review focuses on the investigation of the chemical reduction synthetic route for black TiO 2 nanomaterials, and their proposed association with green applications such as photodegradation of organic pollutants and photocatalytic water splitting. The synthesis methods of black TiO 2 involves the changes from Ti 4+ to Ti 3+ state, into different strategies: (1) The use of highly active hydrogen species such as H 2 , H 2 /Ar or H 2 /N 2 gases, and metal hydrides (NaBH 4 , CaH 2 ), (2) the reduction by active metals such as aluminum, magnesium and zinc, and (3) organic molecules such as imidazole and ascorbic acid.

“…Among the alternative anode materials, TiO 2 has been considered as a striking anode candidate for LIBs due to its high structure stability, long cycle life, low cost, and prominent security . However, its intrinsic demerits of relatively low theoretical capacity and poor rate capability have strictly limited its further application for commercialization . Recently, ternary metal oxides have been deemed as potential anode materials, compared with binary compounds, in terms of more abundant redox chemical reactions, higher electrochemical activity, and electronic conductivity .…”

A facile yet efficient two‐step electrospinning calcination strategy is smartly developed to construct 1D hierarchical coral‐like CoTiO3/Co3O4/TiO2 hybrid nanobelts. The 1D coral‐like nanohybrid is homogeneously constructed from well‐dispersed CoTiO3 nanobelts and uniformly distributed secondary crystalline Co3O4/TiO2 nanoparticle building blocks. When evaluated as anodes for lithium‐ion batteries (LIBs), the hybrid CoTiO3/Co3O4/TiO2 nanobelt electrode exhibits a promising reversible capacity of 722.3 mAh g−1 at 100 mA g−1 after 250 cycles and has excellent cyclability with a capacity of 256.7 mAh g−1 after 1000 cycles at a current density of 2000 mA g−1. The imitating 1D coral‐like structural pattern is beneficial to alleviate the nanoparticle agglomeration and increase the contact area with the electrolyte, leading to the short diffusion path and facilitating the rapid transfer of lithium ions. The high‐level secondary nanobuilding blocks offer a large specific surface area, high surface‐to‐bulk ratio, and fast interfacial ion transport. Herein, it strongly sheds light on the elegant design concept of the hybrid for fabricating next‐generation advanced rechargeable LIBs.

Nitrogen-doped TiO2–C composite nanofibers (TiO2/N–C NFs) were manufactured by a convenient and green electrospinning technique in which urea acted as both the nitrogen source and a pore-forming agent. The TiO2/N–C NFs exhibit a large specific surface area (213.04 m2 g−1) and a suitable nitrogen content (5.37 wt%). The large specific surface area can increase the contribution of the extrinsic pseudocapacitance, which greatly enhances the rate capability. Further, the diffusion coefficient of sodium ions (DNa+) could be greatly improved by the incorporation of nitrogen atoms. Thus, the TiO2/N–C NFs display excellent electrochemical properties in Na-ion batteries. A TiO2/N–C NF anode delivers a high reversible discharge capacity of 265.8 mAh g−1 at 0.05 A g−1 and an outstanding long cycling performance even at a high current density (118.1 mAh g−1) with almost no capacity decay at 5 A g−1 over 2000 cycles. Therefore, this work sheds light on the application of TiO2-based materials in sodium-ion batteries.Electronic supplementary materialThe online version of this article (10.1007/s40820-018-0225-1) contains supplementary material, which is available to authorized users.
