“…2e) which can determine the optical bandgap in semiconductors, was obtained from the UV-vis spectrum of Cu 2 O. The optical bandgap E g of the Cu 2 O thin films can be calculated with the formula (eqn (3)) below 52 ( αhν ) n = A ( hν − E g )where α is the optical absorption coefficient, which is proportional to the absorbance. hν is the energy of the photon from the UV-vis spectrum.…”

Methods for the fabrication of thin films with well controlled structure and properties are of great importance for the development of functional devices for a large range of applications. SILAR, the acronym for Successive Ionic Layer Adsorption and Reaction, is an evolution and combination of two other deposition methods, the Atomic Layer Deposition and Chemical Bath Deposition. Due to a relative simplicity and low cost, this method has gained increasing interest in the scientific community. There are, however, several aspects related to the influence of the many parameters involved, which deserve further deepening. In this review article, the basis of the method, its application to the fabrication of thin films, the importance of experimental parameters, and some recent advances in the application of oxide films are reviewed. At first the fundamental theoretical bases and experimental concepts of SILAR are discussed. Then, the fabrication of chalcogenides and metal oxides is reviewed, with special emphasis to metal oxides, trying to extract general information on the effect of experimental parameters on structural, morphological and functional properties. Finally, recent advances in the application of oxide films prepared by SILAR are described, focusing on supercapacitors, transparent electrodes, solar cells, and photoelectrochemical devices.

[28] Moreover, research efforts have been made to select the most suitable materials as substrates of electrodes, by considering the physical properties which include conductivity, flexibility, integration with membranes, etc., because these properties can significantly affect the photocatalytic activity of TiO 2 . Several substrates have been investigated as the photocatalyst immobilization such as FTO glass, [29,30] carbon paper, [31] porous alumina ceramic, [32] etc.…”

Photocatalysis and photoelectrocatalysis are highly promising for applications in the energy and environment sectors. Several photocatalytic devices based on TiO2 nanotubes grown on two‐dimensional (2D) substrate (such as titanium foil) have been developed, but there has been little research on three‐dimensional (3D) TiO2 nanotubes which are expected to offer significantly enlarged surface area and much improved photocatalytic efficiency. Here, a method of building 3D TiO2 nanotube arrays (3D‐TNTAs) on titanium mesh by anodization via controlling the reaction time and electrolyte is reported. It is found that the electrochemically active area of such a titanium mesh is almost 4 times larger than that of the traditional titanium foil. Moreover, through making composites of graphene oxide and ZnxCdyS onto 3D TiO2 nanotubes, hierarchical nanotube arrays (ZnxCdyS/GO/3D‐TNTAs) are made by calcination‐deposition of graphene oxide followed by a facile successive ionic layer adsorption reaction (SILAR) treatment with ZnxCdyS. Characterization of the ZnxCdyS/GO/3D‐TNTAs indicates that this hierarchical multi‐layered nanostructure has a much improved photoelectrochemical property due to the enlarged surface area and improved electron–hole separation capability, demonstrating the great potential for applications in photoelectrocatalytic devices for environmental technologies.
