“…Typically, a regular network structure is formed on the top of the TiO 2 nanotube, resulting in its large specific surface area [ 25 ]. The top of the TiO 2 NT array has a double-layer honeycomb structure, which is conducive to photocatalysis and energy storage [ 25 , 26 , 27 ]. Therefore, we use the secondary oxidized TiO 2 nanotube (TiO 2 NT) as a matrix to prepare high-performance catalyst and lithium battery anode.…”

As a multifunctional material, TiO2 shows excellent performance in catalytic degradation and lithium-ion storage. However, high electron-hole pair recombination, poor conductivity, and low theoretical capacity severely limit the practical application of TiO2. Herein, TiO2 nanotube (TiO2 NT) with a novel double-layer honeycomb structure were prepared by two-step electrochemical anodization. Honeycombed TiO2 NT arrays possess clean top surfaces and a long-range ordering, which greatly facilitates the preparation of high-performance binary and ternary materials. A binary TiO2 nanotube@Au nanoparticle (TiO2 NT@Au NP) composite accompanied by appropriately concentrated and uniformly distributed gold particles was prepared in this work. Interestingly, the TiO2 nanotube@Au nanoparticle (TiO2 NT@Au NP) composites not only showed the excellent catalytic degradation effect of methylene blue, but also demonstrated large lithium-ion storage capacity (310.6 μAh cm−2, 1.6 times of pristine TiO2 NT). Based on the realization of the controllable fabrication of binary TiO2 nanotube@MoS2 nanosheet (TiO2 NT@MoS2 NS) composite, ternary TiO2 nanotube@MoS2 nanosheet@Au nanoparticle (TiO2 NT@MoS2 NS@Au NP) composite with abundant defects and highly ordered structure was also innovatively designed and fabricated. As expected, the TiO2 NT@MoS2 NS@Au NP anode exhibits extremely high initial discharge specific capacity (487.4 μAh cm−2, 2.6 times of pristine TiO2 NT) and excellent capacity retention (81.0%).

We report the synthesis of novel titanium dioxide nanotube arrays (TNAs) via an anodization process using five different kinds of titanium foils as working electrodes. This reveals that the morphology of TNAs in impacted by the purity, conductivity, and mechanical properties of the titanium sheets. Under the same electrochemical conditions, when titanium foil with purity of 99.7% was used as the working electrode, the TNAs with maximum aspect ratio was obtained compared to that prepared by low purity metal substrate. We also track and observe the morphology of the secondary oxidized TNAs, and demonstrate the relationship with different purites of Ti foils. The fact that the adhesion of anodic TNAs to Ti substrates closely relates to the residual stress of substrates is also revealed. Specifically, cathodic pulse doping results show that the black appearance of TNAs is strongly dependent on the purity of different Ti foils.

Design of nano-porous materials for electrodes is a promising approach for enhancing the storage capacity of electrochemical energy storage devices. In recent years, titanium dioxide (TiO 2 ) nanotube arrays have emerged as an auspicious candidate in this category because of its high surface area, porosity, mechanical strength and excellent transport properties in addition to its low cost, non-toxic and environmental friendly nature that are best suited for supercapacitor electrodes. The unique properties such as unidirectional electron transport, chemical and mechanical stability makes it an interesting option for researchers. The recent advancement in electrochemical nanofabrication has paved the way for precise control over the tube geometry and improved the ease in co-deposition of composite constituents. Methods such as doping, plasma treatment, preferential crystal axis growth, hydrogenation and nitridation have been used to enhance the electrochemical capacitance of titania nanotubes. This article reviews the strategic emergence of TiO 2 nanotube as competent electrode material for supercapacitors and its future scope.
