“…To assess the electrochemical performance of the TiO 2 ww/CN electrode, this work and the other partly reported binder-free and free-standing TiO 2 anode materials in LHCs in the recent five years are compared in Table S2. Compared with rGO modified N-doped carbon foam supporting TiO 2 [ 20 ], foam-like 3D mesopore N-doped carbon assembling TiO 2 nanoparticles [ 53 ], thick mesoporous TiO 2 films [ 54 ], and preferentially oriented TiO 2 nanotubes [ 55 ], the TiO 2 ww/CN electrode in this work has better cycling stability and higher reversible capacity. Besides, TiO 2 ww/CN also shows better cycling stability than TiO 2 layer on N-doped carbon foams [ 15 ], and TiO 2 /super-aligned C nanotube [ 56 ].…”

Wearable and portable mobile phones play a critical role in the market, and one of the key technologies is the flexible electrode with high specific capacity and excellent mechanical flexibility. Herein, a wire-in-wire TiO2/C nanofibers (TiO2 ww/CN) film is synthesized via electrospinning with selenium as a structural inducer. The interconnected carbon network and unique wire-in-wire nanostructure cannot only improve electronic conductivity and induce effective charge transports, but also bring a superior mechanic flexibility. Ultimately, TiO2 ww/CN film shows outstanding electrochemical performance as free-standing electrodes in Li/K ion batteries. It shows a discharge capacity as high as 303 mAh g−1 at 5 A g−1 after 6000 cycles in Li half-cells, and the unique structure is well-reserved after long-term cycling. Moreover, even TiO2 has a large diffusion barrier of K+, TiO2 ww/CN film demonstrates excellent performance (259 mAh g−1 at 0.05 A g−1 after 1000 cycles) in K half-cells owing to extraordinary pseudocapacitive contribution. The Li/K full cells consisted of TiO2 ww/CN film anode and LiFePO4/Perylene-3,4,9,10-tetracarboxylic dianhydride cathode possess outstanding cycling stability and demonstrate practical application from lighting at least 19 LEDs. It is, therefore, expected that this material will find broad applications in portable and wearable Li/K-ion batteries.

“…However, after 600 cycles, the discharge capacity remained at 219.1 mA h g À1 . Compared with the recently reported TiO 2 , 9,14,[26][27][28][29] europium-modified TiO 2 showed an excellent long-term cyclability (see Table 2). Due to the introduction of Eu 3+ /Eu 2+ doping in TiO 2 , the high rate discharge capacity and long-term cycling of TiO 2 were improved; thus the lithium storage performance of TiO 2 was improved.…”

“…In composites such as N-doped carbon assembling TiO 2 NPs, 108 N-doped carbon foam@CNT-TiO 2 109 , N-doped TiO 2 /reduced graphene oxide, 110 flower-like TiO 2 -B graphene composites, 111 mesoporous Ge@TiO 2 , 112 Nb-doped TiO 2 -carbon composites, 113 and MoS 2 nanograin-doped TiO 2 nanofibers, 114 TiO 2 acts as an outer buffer wall, alleviating the change in volume, protecting the direct contact in between doped material and electrolyte, and retarding the formation of SEI (solid electrolyte interphase) film during Li storage. Hence, stored lithium exhibits good performance as anode materials in lithium-ion batteries.…”

Nano-biotechnology deals with the role of biological species in the field of nanotechnology and has gained significant attention in the last few decades. Nano-sized materials have superior physical, chemical, optical, electrical and mechanical properties in comparison with the bulk materials. A number of techniques have been employed so far to synthesize nano-structured materials, and among these, bio-inspired methods are found to be economically viable and environmentally sustainable. Titanium dioxide (TiO 2 ) is one of the most abundant and nontoxic transition metal oxides with high thermal stability, good oxidation and corrosion resistance, good hydrophobicity and non-wettability. All these properties along with a wide band gap make TiO 2 an important material for various applications in the fields of solar cells, sensors, batteries, and supercapacitors. In this review work, a comprehensive study has been carried out on the synthesis of TiO 2 nanoparticles (NPs) using different biological extracts and applications of TiO 2 NPs in the design and development of various electronic devices.
