Summary: The electrochemical water splitting technology is crucial for achieving global carbon neutrality. High-performance electrocatalysts that can operate at high current densities are essential for the industrial implementation of this technology. Recent advancements in this field have led to the development of various catalysts designed specifically for high current densities (> 200 mA cm(-2)). This article discusses these recent advances and summarizes the key factors that influence the catalytic performance in high current density electrocatalysis, including catalyst dimensionality, surface chemistry, electron transport path, morphology, and catalyst-electrolyte interaction. It highlights the importance of a multiscale design strategy that considers these factors comprehensively for developing high current density electrocatalysts. The article also provides insights into the future directions of this emerging field.

Summary: The production of green hydrogen through water electrolysis is crucial for achieving carbon neutrality worldwide. Acidic water electrolysis has gained significant attention due to its higher current density operation and energy conversion efficiency compared to alkaline water electrolysis. However, the four-electron-transfer oxygen evolution reaction (OER) limits the overall efficiency of water electrolysis devices. Recent studies have focused on improving the intrinsic activity, high current density operation, and long-term stability of acidic OER catalysts through strategies such as surface chemistry engineering and constructing porous structures.

Summary: This study successfully fabricates metal oxy(hydroxide) nanosheet structures and demonstrates their outstanding electrocatalytic performance for the oxygen evolution reaction (OER) in saline water. The different structures of NiOOH and NiOOH@FeOOH (NiOOH grown on FeOOH) are formed through electrochemical activation, and the underlayer of FeOOH plays a critical role in enhancing the OER activity of NiOOH. An unconventional dual-sites mechanism (UDSM) is proposed to explain the OER process on NiOOH@FeOOH.

Summary: As an important carbon-neutral energy carrier, green hydrogen produced through water electrolysis using renewable electricity has gained global attention. Polymer electrolyte water electrolyzers (PEWEs) have the potential to play a key role in the green hydrogen market due to their superior performance. However, the slow progress in the development of the membrane electrode assembly (MEA), an essential component of PEWE, hinders the advancement of PEWEs. This review discusses recent progress in MEA materials and design strategies, focusing on cost, activity, and stability of catalysts, distribution and thickness of ionomers, and ion transport efficiency of ion exchange membranes (IEMs). The effects of all components and interlayer interfaces on ions, electrons, and mass transfer in MEA, and consequently, the performance of PEWEs are analyzed. Perspectives on MEA development through optimization of catalyst activity and IEM stability, interface contact between adjacent components, and performance evaluation methods are proposed.
