Abstract ：
Water electrolysis hydrogen production technology directly generates high-purity hydrogen through electrochemical water splitting, serving as a key technology for achieving zero-carbon emission hydrogen production. Alkaline water electrolysis demonstrates marked advantages in efficiency and rapidly developing anode catalysts in an alkaline medium. Nevertheless, the sluggish kinetics of the hydrogen evolution reaction (HER) at the cathode in an alkaline environment constitute a fundamental bottleneck that restricts the extensive application of this technology. Platinum, serving as the benchmark catalyst for the HER, is limited in its large-scale development due to its scarcity and high cost. In comparison, carbon-supported platinum-based catalysts exhibit exceptional HER catalytic activity and stability, driven by their unique electronic architecture and the synergistic effect with the support. In this review, we comprehensively examine the latest progress of carbon-supported platinum-based materials for the alkaline HER, summarize the factors contributing to the slow kinetics of the HER in an alkaline environment, and then focus on the strategies for modifying the carbon substrate and synthesizing carbon-supported platinum-based nanomaterials. Finally, the review critically evaluates existing challenges and proposes targeted research directions to advance Pt-based electrocatalysts for practical alkaline hydrogen evolution systems.

Abstract ：
The rational preparation of efficient and durable electrocatalysts is the key to advancing the development of water electrolysis technology. Noble metal-based materials, such as Pt, Ru, and Ir, have excellent catalytic performance and stability. However, their high cost and low abundance require researchers to explore effective strategies to improve their utilization efficiency. Electrospinning is a facile synthetic method to prepare one-dimensional nanofibers with the desired composition and structure, especially carbon-supported metal-based electrocatalysts with a large specific surface area and high conductivity, through post-processing strategies. This review introduces the recent progress in electrospinning to prepare noble metal-based catalysts for water electrolysis. Specifically, we summarize various strategies for incorporating noble metals into electrospinning nanofibers, as well as their electrocatalytic performance towards hydrogen evolution, oxygen evolution, and overall water splitting. Finally, we propose the opportunities and challenges faced by electrospinning technology in the creation of water electrolysis catalysts, as well as the prospects for future development.

Abstract ：
Single-atom alloys (SAAs) are promising catalysts due to their unique electronic/geometric structures and high atomic efficiency, yet precise control of guest metal atoms and host nanoparticle dispersion remains challenging. This study develops a facile ion exchange-pyrolysis strategy to synthesize ultrafine NiRu SAA nanoparticles confined in porous carbon (NiRu/C) nanosheet arrays. Advanced characterization confirms isolated Ru atoms anchored on Ni nanoparticles with electron transfer from Ni to Ru, achieving uniform dispersion in ultrathin carbon. Theoretical analysis indicates that Ru single atoms optimize reactant adsorption and reduce energy barriers for rate-determining steps, enhancing both hydrogen and oxygen evolution. As bifunctional electrodes in anion-exchange membrane water electrolyzers, NiRu/C demonstrates a low voltage of 1.75 V at 1 A cm-2 at 60 degrees C with 350 h stability, showcasing SAAs' potential for efficient green hydrogen production.
