“…The main limits associated with this technology are the relatively low current density, low operating pressure, cross-over of gases, and low partial-load range [8][9][10][11][12]. On the other hand, the proton exchange membrane (PEM)electrolyzer is an emerging H 2 production technology.…”

This review describes recent advances in electrochemical water electrolysis and rechargeable beyond Li-ion battery research, two emergent and widely employed technologies playing important roles in clean energy production and storage. The principle components of these electrochemical processes are electrode materials, which are currently facing challenges in performance improvement, thus motivating the development of novel electrode materials. This development requires synergistic interactions between experimentalists and theorists with backgrounds in solid state chemistry, condensed matter physics, and materials science and engineering. In light of a large amount of literature covering the topic, we will focus this review on the seminal electrode materials that have been discovered in the last five years, such as transition metal chalcogenides, carbides, and phosphides, as well as 2D layered materials. Intensive cross-disciplinary research is also dedicated to nanostructuring and hybridization of the emerging electrode materials in order to maximize the efficiency and simultaneously to lower the cost of the processes. As the understanding of the nanoscale-related effects deepens, it opens important pathways to the discovery of further materials and their improvement.

NaBH 4 hydrolysis can generate pure hydrogen on demand at room temperature, but suffers from the difficult regeneration for practical application. In this work, we overview the state-of-the-art progress on the regeneration of NaBH 4 from anhydrous or hydrated NaBO 2 that is a byproduct of NaBH 4 hydrolysis. The anhydrous NaBO 2 can be regenerated effectively by MgH 2 , whereas the production of MgH 2 from Mg requires high temperature to overcome the sluggish hydrogenation kinetics. Compared to that of anhydrous NaBO 2 , using the direct hydrolysis byproduct of hydrated NaBO 2 as the starting material for regeneration exhibits significant advantages, i.e., omission of the high-temperature drying process to produce anhydrous NaBO 2 and the water included can react with chemicals like Mg or Mg 2 Si to provide hydrogen. It is worth emphasizing that NaBH 4 could be regenerated by an energy efficient method and a large-scale regeneration system may become possible in the near future.

Abstract:Water electrolysis for hydrogen production has received increasing attention, especially for accumulating renewable energy. Here, we comprehensively reviewed all water electrolysis research areas through computational analysis, using a citation network to objectively detect emerging technologies and provide interdisciplinary data for forecasting trends. The results show that all research areas increase their publication counts per year, and the following two areas are particularly increasing in terms of number of publications: "microbial electrolysis" and "catalysts in an alkaline water electrolyzer (AWE) and in a polymer electrolyte membrane water electrolyzer (PEME).". Other research areas, such as AWE and PEME systems, solid oxide electrolysis, and the whole renewable energy system, have recently received several review papers, although papers that focus on specific technologies and are cited frequently have not been published within the citation network. This indicates that these areas receive attention, but there are no novel technologies that are the center of the citation network. Emerging technologies detected within these research areas are presented in this review. Furthermore, a comparison with fuel cell research is conducted because water electrolysis is the reverse reaction to fuel cells, and similar technologies are employed in both areas. Technologies that are not transferred between fuel cells and water electrolysis are introduced, and future water electrolysis trends are discussed.
