The remarkable properties of carbon-based nanomaterials (CNMs) have stimulated a significant increase in studies on different 0D, 1D and 2D nanostructures, which have promising applications in various fields of science and technology. However, the use of graphite as a raw material, which is essential for their production, limits the scalability of these nanostructures. In this context, petroleum coke (PC), a by-product of the coking process in petrochemical industry with a high carbon content (>80 wt%), is emerging as an attractive and low-cost option for the synthesis of carbonaceous nanostructures. This brief review presents recent research related to the use of PC as a precursor for CNMs, such as graphene and its oxidized (GO) and reduced (RGO) variants, among other carbon-based nanostructures. The work highlights the performance of these materials in specific areas of application. In addition, this review describes and analyzes strategies for transforming low-cost, environmentally friendly waste into advanced technological innovations with greater added value, in line with the UN's 2030 Agenda.
碳基纳米材料（CNMs）的卓越性能激发了对不同零维、一维和二维纳米结构研究的显著增加，这些纳米结构在各种科学技术领域都有广阔的应用前景。然而，石墨作为其生产必不可少的原材料，限制了这些纳米结构的可扩展性。在此背景下，石油焦（PC）作为石化行业焦化过程的副产品，碳含量高（>80 wt%），正成为合成碳质纳米结构的一种有吸引力且低成本的选择。本简要综述介绍了近期有关将石油焦用作碳基纳米材料前驱体的研究，例如石墨烯及其氧化（GO）和还原（RGO）变体，以及其他碳基纳米结构。该工作突出了这些材料在特定应用领域的性能。此外，本综述描述并分析了根据联合国2030年议程将低成本、环境友好型废物转化为具有更高附加值的先进技术创新的策略。
