“…As is well known, owing to the low initial Coulombic efficiency and capacity of carbon materials, exploring carbon-free electrode materials has been deemed as a hotspot worth studying. Therefore, significant progress has been made in the system of NiO@metallic oxide, including Fe 2 O 3 54 , TiO 2 , , Co 3 O 4 , − MnCo 2 O 4 59 , NiCo 2 O 4 , , NiFe 2 O 4 62 , and ZnCo 2 O 4 63 . TiO 2 , as a “zero-strain” material, acted as a template for the growth of NiO, resulting in the regular distribution of NiO. , As shown in Figure f, Zhang et al reported that hierarchical nonwoven fabric NiO/TiO 2 films act as an anode material for lithium-ion batteries.…”

Captured by the high energy density and eco-friendly properties, secondary energy-storage systems have attracted a great deal of attention. For meeting with the demand of advanced systems with both cycling stability and high capacity, a series of tailoring methods have been used. Electrode materials, as the main components of a full cell, play importance roles in capacity contribution. Thus, exploring suitable materials has been deemed to be vital for the development of energy-storage systems. Recently, compared to the traditional carbon-based materials, the considerable electrochemical properties of metal-based samples have been observed. Alternatively, nickel-based materials displayed resource abundance, environmental-friendliness, and high theoretical specific capacity, while the rich exploring activities have been scarily summarized. In this review, the energy-storage performances of nickel-based materials, such as NiO, NiSe/NiSe2, NiS/NiS2/Ni3S2, Ni2P, Ni3N, and Ni(OH)2, are summarized in detail. For some materials with innovative structures, their merits and characteristics were discussed elaborately through four points: (1) the controlling of nanostructures, (2) the complexing of carbon materials, (3) the doping of heteroatoms, and (4) the designing of heterostructures. Significantly, the challenges and prospects of nickel-based materials for secondary battery systems are discussed. This work is expected to offer significant summarization and prospects about physical–chemical designing for nickel-based samples.

“…However, NiO-NTA demonstrated the best rate capability (257,240,216,192,162, and 130 mAh•g −1 ). Chen et al [46] synthesized a TiO 2 -NiO nanoparticle precursor via the sol-gel method, and then obtained TiO 2 -NiO nanoparticles by the calcining treatment at 300 • C for 2 h. The initial capacity of the TiO 2 electrodes was improved from 170 mAh•g −1 to 300 mAh•g −1 at 20 mA•g −1 by introducing NiO into TiO 2 .…”

Titanium dioxide (TiO2), as a potential anode material applied for lithium-ion batteries (LIBs), is constrained due to its poor theoretical specific capacity (335 mAh·g−1) and low conductivity (10−7-10−9 S·cm−1). When compared to TiO2, NiO with a higher theoretical specific capacity (718 mAh·g−1) is regarded as an alternative dopant for improving the specific capacity of TiO2. The present investigations usually assemble TiO2 and NiO with a simple bilayer structure and without NiO that is immersed into the inner of TiO2, which cannot fully take advantage of NiO. Therefore, a new strategy was put forward to utilize the synergistic effect of TiO2 and NiO, namely doping NiO into the inner of TiO2. NiO-TiO2 was fabricated into the nanofibers with a higher specific surface area to further improve their electrochemical performance due to the transportation path being greatly shortened. NiO-TiO2 nanofibers are expected to replace of the commercialized anode material (graphite). In this work, a facile one-step electrospinning method, followed by annealing, was applied to synthesize the Ni-doped TiO2 nanofibers. The Ni doping content was proven to be a crucial factor affecting phase constituents, which further determined the electrochemical performance. When the Ni doping content was less than 3 wt.%, the contents of anatase and NiO were both increased, while the rutile content was decreased in the nanofibers. When the Ni doping content exceeded 3 wt.%, the opposite changes were observed. Hence, the optimum Ni doping content was determined as 3 wt.%, at which the highest weight fractions of anatase and NiO were obtained. Correspondingly, the obtained electronic conductivity of 4.92 × 10−5 S⋅cm−1 was also the highest, which was approximately 1.7 times that of pristine TiO2. The optimal electrochemical performance was also obtained. The initial discharge and charge specific capacity was 576 and 264 mAh·g−1 at a current density of 100 mA·g−1. The capacity retention reached 48% after 100 cycles, and the coulombic efficiency was about 100%. The average discharge specific capacity was 48 mAh·g−1 at a current density of 1000 mA·g−1. Approximately 65.8% of the initial discharge specific capacity was retained when the current density was recovered to 40 mA·g−1. These excellent electrochemical results revealed that Ni-doped TiO2 nanofibers could be considered to be promising anode materials for LIBs.

“…This involves combining the TiO 2 with another material that has a narrow band gap [10]. As a result, several TiO 2 -based heterostructures have been designed in different forms such as: semiconductor n/semiconductor n: TiO 2 -SnO 2 [11], TiO 2 -WO 3 [12], TiO 2 -ZnO [13], SiO 2 -TiO 2 [14] semiconductor n/semiconductor p: TiO 2 -Fe 2 O 3 [15], TiO 2 -Cu 2 O [16], TiO 2 -NiO [17] and noble metal/semiconductor n: Au-TiO 2 [18] , Ag-TiO 2 [19], Pt-TiO 2 [20] Particularly, the metal/semiconductor n combination is widely investigated in various applications; the noble metals impart to the heterostructure a good electrocatalytic performance and super capacitive properties [21,22]. Among the numerous materials that could be combined with TiO 2 and serve to improve its catalytic performances, RuO 2 has raised much interest owing to its chemical and high thermal stability, low resistivity, high resistance to chemical corrosion, and its excellent diffusion properties make it an interesting material in numerous applications [23,24].…”

Polyaniline-Grafted RuO2-TiO2 Heterostructure for the Catalysed Degradation of Methyl Orange in Darkness

Massive industrial and agricultural developments have led to adverse effects of environmental pollution resisting conventional treatment processes. The issue can be addressed via heterogeneous photocatalysis as witnessed recently. Herein, we have developed novel metal/semi-conductor/polymer nanocomposite for the catalyzed degradation and mineralization of model organic dye pollutants in darkness. RuO2-TiO2 mixed oxide nanoparticles (NPs) were modified with diphenyl amino (DPA) groups from the 4-diphenylamine diazonium salt precursor. The latter was reduced with ascorbic acid to provide radicals that modified the NPs and further served for in situ synthesis of polyaniline (PANI) that resulted in RuO2/TiO2-DPA-PANI nanocomposite catalyst. Excellent adhesion of PANI to RuO2/TiO2-DPA was noted but not in the case of the bare mixed oxide. This stresses the central role of diazonium compounds to tether PANI to the underlying mixed oxide. RuO2-TiO2/DPA/PANI nanocomposite revealed superior catalytic properties in the degradation of Methyl Orange (MO) compared to RuO2-TiO2/PANI and RuO2-TiO2. Interestingly, it is active even in the darkness due to high PANI mass loading. In addition, PANI constitutes a protective layer of RuO2-TiO2 NPs that permitted us to reuse the RuO2-TiO2/DPA/PANI nanocomposite nine times, whereas RuO2-TiO2/PANI and RuO2-TiO2 were reused seven and five times only, respectively. The electronic displacements at the interface of the heterojunction metal/semi-conductor under visible light and the synergistic effects between PANI and RuO2 result in the separation of electron-hole pairs and a reduction of its recombination rate as well as a significant catalytic activity of RuO2-TiO2/DPA/PANI under simulated sunlight and in the dark, respectively.
