In the context of even more growing energy demands, the investigation of alternative environmentally friendly solutions, like fuel cells, is essential. Given their outstanding properties, carbon nanohorns (CNHs) have come forth as promising electrocatalysts within the nanocarbon family. Carbon nanohorns are conical nanostructures made of sp carbon sheets that form aggregated superstructures during their synthesis. They require no metal catalyst during their preparation and they are inexpensively produced in industrial quantities, affording a favorable candidate for electrocatalytic reactions. The aim of this article is to provide a comprehensive overview regarding CNHs in the field of electrocatalysis and especially, in oxygen reduction, methanol oxidation, and hydrogen evolution, as well as oxygen evolution from water splitting, underlining the progress made so far, and pointing out the areas where significant improvement can be achieved.
在能源需求不断增长的背景下，研究替代的环保解决方案，如燃料电池，至关重要。鉴于其优异的性能，碳纳米角（CNHs）已成为纳米碳家族中颇具前景的电催化剂。碳纳米角是由sp碳片制成的锥形纳米结构，在合成过程中形成聚集的超结构。它们在制备过程中不需要金属催化剂，并且可以大量廉价地生产，为电催化反应提供了一个理想的候选材料。本文的目的是全面概述碳纳米角在电催化领域的应用，特别是在氧还原、甲醇氧化、析氢以及水分解析氧方面，强调目前取得的进展，并指出可以实现显著改进的领域。
