Abstract
Graphene's outstanding electrical,thermal,mechanical,and chemical properties make it a promising material for electronics,energy storage,protective coat-ings,catalysis,and environmental remediation.Neverthe-less,its large-scale use is hindered by high synthesis costs,process complexities,and integration issues.Among the available methods for its production,chemical vapor de-position(CVD)on metals is the most scalable,in which copper is widely used because of its low carbon solubility and excellent monolayer control.However,Cu substrates are costly($8-10/kg),subsequent transfer steps introduce defects,and the obtained graphene is poorly matched to structural components.Iron-based substrates provide an at-tractive alternative,offering much lower material cost,dir-ect compatibility with steel infrastructure,reduced growth temperatures,and intrinsic functionalities such as magnet-ism and catalytic activity that enable new applications.The growth of graphene on pure iron,iron alloys,and iron-Based on nanoparticles is analyzed,focusing on growth mechanisms,substrate engineering,and characterization approaches tailored to specific challenges like carbide formation.Ap-plications including corrosion-resistant coatings,electronics,energy storage,catalysis,water treatment,and electromagnetic shielding are considered.Despite the limitation of high carbon solubility,iron can be exploited for controlled multilayer forma-tion which is useful for barrier and energy applications,while alloying and process control enable the production of tunable mono layer or few-layer films,making iron-based CVD graphene a versatile,cost-effective platform.关键词
