The electrochemical oxygen reduction reaction has received increasing attention as a relatively green, safe and sustainable method for in situ hydrogen peroxide (HO) production. Recently, significant achievements have been made to explore carbon-based (noble metal-free) low-cost and efficient electrocatalysts for HO electroproduction, which could potentially replace the traditional anthraquinone process. However, to realize industrial-scale implementation, a highly active and selective catalytic material is needed. In this review paper, we first expound on the oxygen reduction reaction (ORR) mechanism, which is the origin of in situ HO production. Then, the recent progress in the development of modified carbon-based catalysts is reviewed and classified, corresponding to their physical or chemical modulation. Furthermore, an overview is provided of the available examples from pilot/large-scale applications. Finally, an outlook on the current challenges and future research prospects to transfer the lab-developed catalysts into pilot or industrial-scale reactors is briefly discussed.
电化学氧气还原反应作为一种相对绿色、安全和可持续的原位过氧化氢（HO）生产方法，受到了越来越多的关注。最近，在探索用于 HO 电生产的基于碳（无贵金属）的低成本和高效电催化剂方面取得了重大进展，这可能会取代传统的蒽醌工艺。然而，要实现工业规模的实施，需要一种高活性和选择性的催化材料。在这篇综述论文中，我们首先阐述了氧气还原反应（ORR）机制，这是原位 HO 生产的起源。然后，综述并分类了最近在改性碳基催化剂方面的进展，对应于它们的物理或化学调制。此外，还概述了从小型试验/大型应用中获得的可用实例。最后，简要讨论了将实验室开发的催化剂转化为中试或工业规模反应器所面临的当前挑战和未来研究前景。
