由于碳可以采用三种不同的轨道杂化，各种碳纳米同素异形体的存在在维度上也不同，已经证实了其他结构的预测和预期在未来出现。尽管2D石墨烯、1D碳纳米管或0 D富勒烯、纳米金刚石和碳量子点的许多独特特征和应用已经被大量探索，但任何现有的碳同素异形体都不能提供有竞争力的磁性。对于具有挑战性的应用，碳纳米同素异形体用磁性物质，特别是氧化铁性质的磁性物质官能化，这是由于它们有趣的磁性（超顺磁性和在外部磁场下的强磁响应）、容易获得、生物相容性和低成本。此外，铁氧化物（磁铁矿，磁赤铁矿，赤铁矿）和碳纳米结构的组合带来了增强的电化学性能和（光）催化能力，由于协同和合作效应。这项工作的目的是审查这些先进的应用铁氧化物支持的纳米碳复合材料，其中铁氧化物发挥了不同的作用。详细讨论了碳/氧化铁纳米复合材料的各种结构、合成方法、物理化学性质和应用。特别关注碳纳米管和稀有形式（中孔碳，纳米泡沫）与磁性氧化铁载体的混合物，用于先进的环境技术。综述了石墨烯/氧化铁纳米复合材料在储能、生物医学、环境修复等领域的巨大应用潜力。在各种讨论的医疗应用中，强调零维富勒烯和碳量子点的磁性复合材料是复杂治疗诊断学和双磁荧光成像的有前途的候选者。
Owing to the three different orbital hybridizations carbon can adopt, the existence of various carbon nanoallotropes differing also in dimensionality has been already affirmed with other structures predicted and expected to emerge in the future. Despite numerous unique features and applications of 2D graphene, 1D carbon nanotubes, or 0D fullerenes, nanodiamonds, and carbon quantum dots, which have been already heavily explored, any of the existing carbon allotropes do not offer competitive magnetic properties. For challenging applications, carbon nanoallotropes are functionalized with magnetic species, especially of iron oxide nature, due to their interesting magnetic properties (superparamagnetism and strong magnetic response under external magnetic fields), easy availability, biocompatibility, and low cost. In addition, combination of iron oxides (magnetite, maghemite, hematite) and carbon nanostructures brings enhanced electrochemical performance and (photo)catalytic capability due to synergetic and cooperative effects. This work aims at reviewing these advanced applications of iron-oxide-supported nanocarbon composites where iron oxides play a diverse role. Various architectures of carbon/iron oxide nanocomposites, their synthetic procedures, physicochemical properties, and applications are discussed in details. A special attention is devoted to hybrids of carbon nanotubes and rare forms (mesoporous carbon, nanofoam) with magnetic iron oxide carriers for advanced environmental technologies. The review also covers the huge application potential of graphene/iron oxide nanocomposites in the field of energy storage, biomedicine, and remediation of environment. Among various discussed medical applications, magnetic composites of zero-dimensional fullerenes and carbon dots are emphasized as promising candidates for complex theranostics and dual magneto-fluorescence imaging.
