“…Similarly, morphological changes have been reported for the manganese oxide prepared by acetate, chloride and sulfate precursors. [22] Next, the generated materials were further characterized using XRD and BET methods. Figure 2a presents the X-ray diffraction (XRD) patterns of the nickel cobalt oxides obtained from various precursors.…”

“…[21] Shaikh et al have studied the different precursor's effects on the electrochemical properties of manganese oxide thin films prepared by successive ionic layer adsorption. [22] Recently, mixed transition metal oxides (MTMO) received an increase interest due to their electrochemical and electrocatalytic properties, leading to their use in various applications, including supercapacitors, metal air batteries and fuel cells. [23,24,25,26] Within this materials class, spinel nickel cobaltite oxide (Ni x Co 3À x O 4 ) has been reported as a promising materials.…”

The Effect of Heteroatom Doping on Nickel Cobalt Oxide Electrocatalysts for Oxygen Evolution and Reduction Reactions

The synthesis of nickel cobalt oxide materials and their electrocatalytic performance toward the oxygen reduction and evolution reactions are reported. Nickel cobalt oxides were synthesized in a sol‐gel process with different precursors, namely nitrate, sulfate, and chloride. Structural analyses show that the structures have mesoporous morphologies and indicate the formation of nickel cobalt oxide spinel structures with a size ranging from 35 to 65 nm. Furthermore, the physicochemical properties differ depending on the nature of the selected precursors, including the materials’ morphology and the chemical composition. Electrocatalytic investigations demonstrate that the catalytic activity toward the oxygen reduction reaction (ORR) could be modulated between two‐ and four‐electron pathways, depending on the precursors used. The Cl−NiCoO sample displays a selective two‐electron reduction of O2, with H2O2 production higher than 90 %. The sample prepared using sulfate displays the highest performance toward the oxygen evolution reaction (OER), with a low overpotential value (0.34 V) to drive a current density of 10 mA.cm−1. Overall, these results confirm that the chemical composition of the precursor used during the nanomaterials synthesis can be used to tune the electrocatalytic performances toward ORR and OER.

“…A study involving the acetate, chloride and sulfate of Mn was recently conducted to deposit Mn 3 O 4 films by successive immersions of stainless-steel substrates in 0.1 m Mn precursor solutions followed by 1 m NaOH solution for 20 s each with intermediate rinses in distilled water for 10 s, for a total deposition of 150 cycles. [203] Again, distinctive differences due to the type of precursor used could be identified: the lowest crystallite size was detected for Mn(CH 3 COO) 2 (15 nm) , followed by MnSO 4 (27 nm), and MnCl 2 (34 nm) . SEM micrographs of fabricated films are presented in Figure 8f-h, exhibiting a compact grain structure for the film prepared by Mn(CH 3 COO) 2 and a greater porosity in the film fabricated by MnCl 2 .…”

“…These films were used for energy storage applications, with slightly better performance in terms of charge storage performance for films prepared using MnCl 2 and MnSO 4 compared to those prepared from Mn(CH 3 COO) 2 . [203] In both cases of ZnO and Mn 3 O 4, chloride precursor seems to give rise to larger crystallites suggesting a key role of the counterion participating in the oxide formation.…”

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.
