“…The increased ion diffusion on a cathode at the lower duty cycle with the longer anodic reaction time can induce the frequent adsorption of ionic species. Therefore, the decrease in the duty cycle of the pulse-reverse Ni-P electrodeposition can lead to the increase in the nucleation rate and the inhibition of the grain growth ( Chandrasekar and Pushpavanam, 2008 ; Wahyudi et al, 2019 ). The average grain size of Ni-P electrodeposits decreased from 401 nm for the duty cycle of 100% to 263 nm for the duty cycle of 50%.…”

Nickel phosphide (Ni-P) films as a catalytic cathode for the hydrogen evolution reaction (HER) of a water splitting were fabricated by a pulse-reverse electrodeposition technique. The electrochemical behaviors for the electrodeposition of Ni-P were investigated by the characterization of peaks in a cyclic voltammogram. The composition of the electrodeposited Ni-P alloys was controlled by adjusting duty cycles of the pulse-reverse electrodeposition. The HER electrocatalytic properties of the Ni-P electrodeposits with an amorphous phase as a function of phosphorous contents existing in Ni-P were electrochemically characterized by the analysis of overpotentials, Tafel slopes, and electrochemical impedance spectrometry. Additionally, the elemental Ni-embedded crystalline Ni3P was prepared by an annealing process with the amorphous Ni69P31 electrodeposit with high contents of phosphorus. The crystalline structure with Ni inclusions in the matrix of Ni3P was formed by the precipitation of excess Ni. The electrocatalytic properties of crystalline Ni3P with elemental Ni inclusions were also investigated by electrochemical characterization.

“…3,12 The micro structure of both dendritic and cauliflowerlike particles was similar and consisted of agglomerates of approximately spherical grains. Copper as powder can be obtained by all available electrolysis techniques including both the constant 3,[12][13][14][15][16][17][18][19] and pulse reverse 3,15,[21][22][23] regimes of electrolysis. The main parameters determining the particle size and distribution are: the type and composition of electrolyte, temperature, the type of working electrode, circulation rate, a design of experiments, etc.…”

Copper electrodeposition in a form of powder was examined using the pulsating overpotential (PO) regime from the sulfate electrolyte without or with an addition of various concentrations of chloride ions. Morphological and structural characteristics of the produced particles were analyzed by the scanning electron microscope (SEM) and the X-ray diffraction (XRD) method. The final morphology of Cu powders was determined with two parallel processes: a) suppression of hydrogen evolution reaction due to pause duration considerably longer than the deposition time, and b) catalytic effect of added chlorides. Depending on the amplitude of overpotential applied, addition of chlorides into the solution led to either an appearing of dendrites or to formation of very branchy dendrites, what confirms a catalytic effect of these ions on the process of Cu electrolysis. The novel forms of copper dendrites, such as the needle-like and the 2D (two dimensional), were identified in this investigation, and the catalytic effect of chlorides on copper electrodeposition has been just discussed by morphological analysis of these dendritic forms. The XRD analysis of the copper dendrites obtained with an addition of chlorides showed predominantly oriented the Cu crystallites in (111) plane.https://mc04.manuscriptcentral.com/jes-ecs

Micro‐supercapacitors emerge as an important electrical energy storage technology expected to play a critical role in the large‐scale deployment of autonomous microdevices for health, sensing, monitoring, and other IoT applications. Electrochemical double‐layer capacitive storage requires a combination of high surface area and high electronic conductivity, with these being attained only in porous or nanostructured carbons, and recently found also in conducting metal–organic frameworks (MOFs). However, techniques for conformal deposition at micro‐ and nanoscale of these materials are complex, costly, and hard to upscale. Herein, the study reports direct, one step non‐sacrificial anodic electrochemical deposition of Ni3(2,3,6,7,10,11‐hexaiminotriphenylene)2 – Ni3(HITP)2, a porous and electrically conducting MOF. Employing this strategy enables the growth of Ni3(HITP)2 films on a variety of 2D substrates as well as on 3D nanostructured substrates to form Ni3(HITP)2 nanotubes and Pt@ Ni3(HITP)2 core–shell nanowires. Based on the optimal electrodeposition protocols, Ni3(HITP)2 films interdigitated micro‐supercapacitors are fabricated and tested as a proof of concept.
