Abstract
|
Titanium dioxide (TiO2) has received intense interest from the research community within the past two decades. It is a versatile material that exhibits promising properties for several high-tech applications, e.g., photovoltaics, photocatalysis, photoelectrochemical water splitting, and supercapacitors. Amongst, TiO2 nanotube arrays combined with electrospun nanofibers can be considered to be one of the most attractive electrode materials for electrochemical performance owing to its high theoretical specific capacitance, low cost, natural abundance, and environmental friendliness.
