“…55 The electrodeposition of Mo in NaCl-KCl-MoCl 3 melt was studied by pulse electrolysis at 1053 K. When the average current density was controlled between 2-6 A cm −2 , it is found that the current density would directly affect the grain size and the coating roughness. 56 As shown in Fig. 7, with the increase of current density, its shape gradually becomes spherical.…”

High temperature molten salt electrochemistry (MSE) plays a crucial role in the fields of metallurgy, materials, chemical industry and many other important areas. However, the traditional constant potential or constant current electrolysis has low current efficiency and poor product performance, so researchers often use pulse-electrolysis strategy to address this challenge. In this review, we present a discussion on the application of pulse technology in high temperature MSE. Then, we clarify the influence of key factors in the pulse electrolysis process and the internal mechanism of the influence is analyzed. Finally, we conclude with a perspective on the challenges and development directions of pulse electrolysis in high temperature MSE.

“…Investigation in surface structure changes has primarily focused on the reconstruction of surface nanostructures, including alterations in crystal surfaces, defects, and roughness. Electrodeposition studies have demonstrated that specific pulse parameters, such as cathode current, average cathode current density, and the ratio of relaxation time to pulse time (T r /T c ) enabled continuous depositions of Molybdenum (Mo) with a preferred grain orientation (110), as depicted in Figure 5e-h [105]. Engelbrecht et al observed that a positive up-potential resulted in a rise in grain reorganization.…”

Pulsed electrolysis endowed merits of high current density, low energy consumption, and simple operation; thus, a booming in their publication numbers has been witnessed in recent years. In this review, we aim to summarize the state-of-the-art pulsed current/potential strategy to enhance electrochemical reactions, such as oxygen reduction reactions (ORR), CO2 reduction (CO2RR), CO reduction (COR), etc. It begins with historic analysis of pulsed electrolysis via a bibliometric method, aiming at providing a progress over the course of around 40 years in a quantitative way. Then, the definition along with its influence of electronic effect, double layer effect and mass transport have been reviewed based on a mechanism point of view for the first time. To sum up the review, several current challenges and future prospects of pulsed electrolysis have provided for the future smart design of electrochemical process.
