Developing alternatives to noble-metal-based catalysts toward the oxygen reduction reaction (ORR) process plays a key role in the application of low-temperature fuel cells. Carbon-based, precious-metal-free electrocatalysts are of great interest due to their low cost, abundant sources, active catalytic performance, and long-term stability. They are also supposed to feature intrinsically high activity and highly dense catalytic sites along with their sufficient exposure, high conductivity, and high chemical stability, as well as effective mass transfer pathways. In this Review, we focus on carbon-based, precious-metal-free nanocatalysts with synergistic modulation of active-site species and their exposure, mass transfer, and charge transport during the electrochemical process. With this knowledge, perspectives on synergistic modulation strategies are proposed to push forward the development of Pt-free ORR catalysts and the wide application of fuel cells.

碳基无贵金属电催化剂用于氧气还原反应的协同调节

在氧气还原反应（ORR）过程中开发贵金属催化剂的替代品在低温燃料电池的应用中起着关键作用。碳基无贵金属电催化剂由于其低成本，丰富的来源，有效的催化性能和长期稳定性而备受关注。它们还应具有内在的高活性和高密度的催化位点，以及足够的暴露，高电导率和高化学稳定性以及有效的传质途径。在这篇综述中，我们重点研究具有活性中心物种及其在电化学过程中的暴露，传质和电荷传输的协同调节的基于碳的无贵金属纳米催化剂。有了这些知识，
