English
This review surveys plasma-assisted surface modification of carbon materials for electrocatalytic energy conversion and storage. It covers plasma generation, reactive species, surface-interaction mechanisms, and key parameters (gas, power, pressure, time) driving heteroatom doping, defect engineering, and functionalization, then assesses effects on ORR, OER, and HER performance. Advantages, scalability limits, reproducibility challenges, and future directions such as operando diagnostics and single-atom catalysts are discussed.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
水素製造・燃料電池の電極触媒コスト低減は、日本の水素社会戦略やGX推進における技術的基盤となる。ただし本稿は材料科学のレビューであり、SSBJ・有報・投資家対応など開示実務との直接の接点は乏しい。
In the global GX context
Electrocatalyst cost and performance underpin green hydrogen and fuel-cell deployment, which are central to global transition pathways and industrial decarbonization. However, as a materials-science review it does not engage TCFD/ISSB/CSRD disclosure frameworks, so its relevance is technological rather than disclosure-oriented.

📄 Abstract（原文）
Carbon-based materials are widely employed in electrocatalytic energy conversion and storage technologies owing to their high electrical conductivity, chemical stability, tunable structure, and low cost. However, the limited intrinsic activity and surface inertness of pristine carbon materials often necessitate surface modification to generate catalytically active sites and improve interactions with reactants and electrolytes. Among the available approaches, plasma functionalization has emerged as a versatile, rapid, solvent-free, and potentially resource-efficient technique that enables systematic tuning of surface chemistry while often limiting modification primarily to the near-surface region. This review discusses the fundamentals of plasma-assisted surface modification of carbon materials, including plasma generation, reactive species, plasma-surface interaction mechanisms, and the influence of key processing parameters such as gas composition, power, pressure, and treatment time. Particular attention is devoted to plasma-induced heteroatom doping, defect engineering, surface functionalization, and the dynamic structural evolution of carbon frameworks during treatment. The impact of these modifications on the physicochemical properties and electrocatalytic performance of carbon materials is critically examined with respect to representative reactions, including the oxygen reduction, oxygen evolution, and hydrogen evolution reactions. The advantages, limitations, and scalability of plasma technologies are also discussed, along with current challenges in process control and reproducibility. Finally, future opportunities involving operando diagnostics, single-atom catalysts, advanced porous carbon architectures, and industrial-scale plasma processing are highlighted. Plasma processing offers a versatile route to carbon surface and catalyst-interface engineering, although standardized reporting and quantitative plasma-structure-performance relationships are still required for rational process design and scale-up.
