The design and synthesis of highly stable, low‐cost electrocatalysts for the oxygen reduction reaction to supersede noble‐metal catalysts is critical for their application in the field of fuel cells. Herein, we report a facile approach for the synthesis of CeO2 encapsulated by iron, sulfur, and nitrogen‐doped carbon nanoparticles (CeO2@Fe,S,N−C NPs) by pyrolyzing CeO2@polypyrrole, which is obtained in the presence of sodium dodecylbenzene sulfonate as a surfactant and FeCl3 as an oxidant during the polymerization of pyrrole on the CeO2 surface. As Fe and S are effectively doped into the N‐doped carbon derived from polypyrrole, a large number of active sites are created, which greatly enhances the catalytic activity of the sample. The achieved sample displays excellent catalytic activity with an onset and halfwave potential of 0.924 V and 0.835 V, respectively, and a limiting current density of 5.45 mA cm−2 at the potential of 0.4 V vs. RHE. Moreover, it illustrates a high durability and strong methanol tolerance, endowing it with the prospect of applications in energy conversion.

“…Another direction to improve ORR activity is to construct hierarchically porous carbon substrates which are positive to mass transport and active sites exposure. Liu et al [82] prepared hierarchically porous N,Scodoped carbon with FeS NPs, which showed efficient ORR activity outperforming that of Pt/C. However, a recently reported research showed that Fe 1−x S/S impaired the ORR activity [83].…”

It is crucial to develop low-cost and highly efficient catalysts for oxygen reduction reaction (ORR) which is the key process in electrochemical energy conversion and storage devices. Transition metal-based nanoparticles/carbon materials are an important class of non-noble metal catalysts that have attracted considerable research interest. The topic of this review is mainly focused on carbon encapsulated Fe/Cobased nanoparticles catalysts for ORR, and these catalysts are summarized in categories of metals, oxides, carbides, phosphides, sulfides and hybrid nanoparticles. The structures and morphologies of the carbon matrix as well as compositions of nanoparticles have great influence on the catalytic performance. Numerous catalysts display excellent ORR activity and stability in alkaline media but only a few are efficient in acidic media. In addition, challenges and further strategies on the development of this type of carbon encapsulated nanoparticles catalysts are also proposed.
