“…The TiO 2 nanoarray structure used directly as an electrode material had an area capacitance (1 mV s −1 /911 μF cm −2 ) several orders magnitudes larger when compared to the capacitance of nanoparticles (1 mV s −1 /180 μF cm −2 ) [ 211 ]. Additionally, the performance of the supercapacitor was proportional to the aspect ratio of the nanotubes [ 212 ].…”

Because of their extensive specific surface area, excellent charge transfer rate, superior chemical stability, low cost, and Earth abundance, nanostructured titanium dioxide (TiO2) arrays have been thoroughly explored during the past few decades. The synthesis methods for TiO2 nanoarrays, which mainly include hydrothermal/solvothermal processes, vapor-based approaches, templated growth, and top-down fabrication techniques, are summarized, and the mechanisms are also discussed. In order to improve their electrochemical performance, several attempts have been conducted to produce TiO2 nanoarrays with morphologies and sizes that show tremendous promise for energy storage. This paper provides an overview of current developments in the research of TiO2 nanostructured arrays. Initially, the morphological engineering of TiO2 materials is discussed, with an emphasis on the various synthetic techniques and associated chemical and physical characteristics. We then give a brief overview of the most recent uses of TiO2 nanoarrays in the manufacture of batteries and supercapacitors. This paper also highlights the emerging tendencies and difficulties of TiO2 nanoarrays in different applications.

“…The areal capacitance of Fe2O3/VGN can be improved further by controlling the aspect ratio of nanorices and annealing temperature. [48,49] The presence of well-defined redox peaks in CV is a clear indication of the pseudocapacitive charge storage mechanism. However, to quantify its contribution, we have estimated the b-value and is found to be 0.59 as shown in Fig.…”

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.
