“…In previous methods, there have been some serious disadvantages, such as high-temperature annealing (150 °C-900 °C), high deposition pressure (10 −5 -10 −4 Torr), time-consuming nature (2-12 h), and the use of expensive instrumentation and chemicals (8,24,26). However, in this study, we have used a simple two-step anodization technique to obtain the carbon nanopillar array (temperature (60 °C), deposition pressure (10 −6 Torr), and time (2 h).…”

Carbon-based nanostructures have attracted extensive interest in obtaining advanced sensing electronic devices in environmental and biological monitoring applications as an alternative to conventional materials. Herein, the facile preparation, control of the growth, and artificial intelligence–based morphological information of the carbon nanopillar array in the Anodized Aluminum Oxide (AAO) template were investigated. A facile approach for controlling the growth of the nanostructure was proposed as a two-step anodization technique for AAO and Plasma Enhanced Chemical Vapor Deposition (PECVD) for carbon nanopillar array. It involved the competitive carbon deposition between the carbon nanopillars electrodeposited on the AAO template and at the bottom of the pores of AAO under vacuum conditions. The morphology and structure of the prepared carbon nanopillars were reported in detail. Hexagonally straight AAO nanotubes were approximately 65 nm in diameter and 360 nm in length, with 90 nm interpore distances. The AAO nanotube density is approximately 1.75x1014 cm-2. Carbon nanopillars with a width of ~60 nm were used to create a low-dimensional nanostructure. This controllable preparation leads to the facile and impressive preparation of a free-standing carbon nanopillar array, especially for various chemical sensor applications.

“…Due to its simplicity and robustness, hard-template electrodeposition is the most widely applied strategy for electrosynthesizing polymeric, metallic, alloyed, or semiconducting nanowires or nanorods, one that offers controlled properties and the controlled definition of shape 29,[98][99][100][101][102][103][104][105] .…”

Recent progress in the electrochemical deposition of ZnO nanowires: Synthesis approaches and applicationsIn the last decade, nanostructuration is a demanding research topic due to the observation of interesting properties and, in consequence, applications on these nanostructures. This review collects the synthesis and possible applications of ZnO nanowires grown by electrodeposition and electroless methods. Respect to the synthesis of ZnO nanowires, growth mechanism and parameters are analysed depending on the technique used, electrodeposition or electroless. The mechanism growth of the nanowires using templateless and hard-templates is analysed resulting in different architecture of the ZnO nanowires. Moreover, ZnO nanowires and hybrid materials based on ZnO are also considered. Depending on the architecture of ZnO nanowires, the properties and applications are different.This review also studies the properties and applications in which ZnO nanowires can be used and how these applications are different depending on the architecture of the nanostructure. This review gives a complete perspective referent to the synthesis, properties and application of ZnO nanowires grown by electrosynthesis techniques.

“…For the fabrication of the electrodes, the electrochemical technique was chosen because it is flexible and allows the control of the composition of the alloy by tuning the electrodeposition bath composition [ 77 , 78 ]. As reported earlier, CP was chosen as a support for the electrodeposition processes and the deposition parameters were optimized to obtain a deposit that covered only the CP fibers.…”

To realize the benefits of a hydrogen economy, hydrogen must be produced cleanly, efficiently and affordably from renewable resources and, preferentially, close to the end-users. The goal is a sustainable cycle of hydrogen production and use: in the first stage of the cycle, hydrogen is produced from renewable resources and then used to feed a fuel cell. This cycle produces no pollution and no greenhouse gases. In this context, the development of electrolyzers producing high-purity hydrogen with a high efficiency and low cost is of great importance. Electrode materials play a fundamental role in influencing electrolyzer performances; consequently, in recent years considerable efforts have been made to obtain highly efficient and inexpensive catalyst materials. To reach both goals, we have developed electrodes based on Pd–Co alloys to be potentially used in the PEMEL electrolyzer. In fact, the Pd–Co alloy is a valid alternative to Pt for hydrogen evolution. The alloys were electrodeposited using two different types of support: carbon paper, to fabricate a porous structure, and anodic alumina membrane, to obtain regular arrays of nanowires. The goal was to obtain electrodes with very large active surface areas and a small amount of material. The research demonstrates that the electrochemical method is an ideal technique to obtain materials with good performances for the hydrogen evolution reaction. The Pd–Co alloy composition can be controlled by adjusting electrodeposition parameters (bath composition, current density and deposition time). The main results concerning the fabrication process and the characterization are presented and the performance in acid conditions is discussed.
