Fuel cells represent the most suitable energy conversion, capable of.addressing energy crises and environmental pollution. Recently, as one of.nonprecious metal catalysts (NPMCs), the MC@N-C (M = Fe, Co, Ni, Mo, W).catalysts, especially for Fe3C encased in carbon layer (denoted as Fe3C@N-C).have emerged as promising replacements for costly Pt-based catalysts for.oxygen reduction reaction (ORR). This review highlights the synthetic strategies.undertaken such as hard template, soft template, and template-free.methods for deriving enhancements in electrocatalytic activity and durability..It also provides a comparison on the synthetic methods and catalytic.performance and points out issues in the ORR measurements and activity.comparison. In addition, understanding of the proposed active sites and corresponding.mechanisms for ORR are covered. The recent advances shed light.on contributions of morphology, hierarchical pore structures, density and dispersion.of active sites, and synergistic effects of multiple active sites, which.endow Fe3C@N-C electrocatalysts with enhanced ORR performance. These.interesting effects are attained as a result of increased exposure and accessibility.of the active sites to O2 molecules, faster charge and mass transfer, and.finally, protection of active sites by carbon shells. Finally, the challenges and.perspectives to further improve performance of Fe3C@N-C are discussed.
