Summary: The current global demand for green H2 from water necessitates the use of an efficient and robust catalyst to reduce greenhouse gas emissions. Transition metal phosphide (TMP) based catalysts have emerged as viable alternatives to state-of-the-art Pt/C catalysts for the hydrogen evolution reaction (HER). However, further investigation is needed to assess the recent development and progress of TMP-based catalysts for HER, in order to encourage the development of efficient, robust, and durable catalysts. This review provides an overview of the recent research progress on TMPs for electrochemical HER, including nanostructure synthesis, integration with support materials, and hybrid structure synthesis. The review also discusses the fundamental aspects of HER kinetics, the effect of composition and pH on different types of TMPs, and the need for pre and post-analysis to evaluate the true identity of active sites and the durability of TMPs.

Summary: Developing efficient and inexpensive electrocatalysts for the hydrogen evolution reaction (HER) is crucial for the commercial viability of electrochemical clean energy technologies. Transition metal phosphides (TMPs) have been recognized as attractive HER catalytic materials due to their abundant reserves, unique structure, tunable composition, and high electronic conductivity. However, the HER activity of TMPs is still limited by various issues and performance bottlenecks. This review addresses these issues, provides explanations and solutions based on the origins of HER catalytic activity in TMPs, presents strategies to improve HER performance, and proposes critical scientific issues for constructing high-efficiency TMP-based electrocatalysts. Challenges and future directions for this research field, including the HER reaction process, catalytic mechanism research, TMP-based catalyst construction, and application expansion, are also discussed.

Summary: This study investigates the breathing behavior of solid electrolyte interphases (SEIs) induced by discharging/charging on Fe2O3 conversion-type anodes using cryogenic transmission electron microscopy and spectroscopy. The SEI breathing involves swelling and contracting upon lithiation and de-lithiation due to reversible compositional changes. Bare Fe2O3 anodes develop unstable SEI layers with thickness variation and excessive growth. By applying N-doped carbon coating on Fe2O3, a thinner and chemically more stable SEI layer develops, resulting in significantly enhanced cycling stability.
