The rise of CO₂ in the atmosphere, which results in severe climate change and temperature increase, is known as the major reason for the greenhouse effect. Reducing CO₂ to value-added products is an attractive solution to this severe problem, along with addressing the energy crisis, to which the catalysts being employed are of vital importance. Due to their high porosity and tunable compositions, metal-organic frameworks (MOFs) show great potential in energy conversion systems. By thermal or chemical treatment methods, the MOFs are easily turned into MOF-derived carbon nanomaterials. The much higher level of conductivity enables MOF-derived carbon nanomaterials to be employed in CO₂ conversion processes. The present review, discusses the state of the art of MOF-derived carbon nanomaterials in CO₂ electrochemical, photocatalytic, and thermal reduction applications. The corresponding reaction mechanisms and influence of various factors on catalyst performance are elaborated. Finally, the deficiencies and recommendations are provided for future progress.

大气中CO ₂的升高导致严重的气候变化和气温升高，被认为是造成温室效应的主要原因。将CO ₂还原为增值产品是解决这一严重问题以及解决能源危机的一个有吸引力的解决方案，而所使用的催化剂对于解决能源危机至关重要。由于其高孔隙率和可调节的成分，金属有机框架（MOF）在能量转换系统中显示出巨大的潜力。通过热处理或化学处理方法，MOF很容易转化为MOF衍生的碳纳米材料。更高水平的电导率使得 MOF 衍生的碳纳米材料能够用于 CO ₂转化过程。本综述讨论了 MOF 衍生的碳纳米材料在 CO ₂电化学、光催化和热还原应用中的最新技术。阐述了相应的反应机理以及各种因素对催化剂性能的影响。最后提出了不足之处以及今后改进的建议。
