The activation and conversion of small molecules (H2, O2, H2O, CO2, N2, CH3OH, and C2H5OH) in energy‐related systems has attracted researchers’ attentions around the world. The conversion of these molecules plays a key role in renewable energy storage and conversion systems, and for that, the electrocatalysis and photocatalysis processes are considered as clean and efficient strategies. Numerous materials are designed to promote the conversion process to satisfy the different requirements for efficiency and selectivity. Due to the flexible switching between Ce3+ and Ce4+ with rich oxygen defects, CeO2‐based materials display excellent performance in all the related reaction processes. Herein, the CeO2‐based electro(photo)catalysts according to different reactions are summarized. Specifically, the influence of material compositions, morphologies, and structures on catalytic performance is discussed, and the significant role of CeO2 is emphasized. Finally, several approaches are advocated to promote the development of CeO2‐based electro(photo)catalysis and accelerate their industrial application.

“…The hybrid SnO 2 @PtRhNi/C catalysts exhibited excellent mass activity and specific activity that were 6-fold and 10-fold higher than the commercial Pt/C catalyst, respectively (Figure 4j). The CeO 2 addition also proved effective in enhancing the catalytic activity of Pt-based catalysts in EOR due to its interaction with Pt and the ability in oxygen storage [72,73]. Xu et al adopted a simple electro-deposition method to prepare CeO 2 -modified Pt/Ni catalysts which exhibited advanced catalytic performance for EOR in alkaline media [60].…”

Direct ethanol fuel cells (DEFCs) have emerged as promising and advanced power systems that can considerably reduce fossil fuel dependence, and thus have attracted worldwide attention. DEFCs have many apparent merits over the analogous devices fed with hydrogen or methanol. As the key constituents, the catalysts for both cathodes and anodes usually face some problems (such as high cost, low conversion efficiency, and inferior durability) that hinder the commercialization of DEFCs. This review mainly focuses on the most recent advances in nanostructured catalysts for anode materials in DEFCS. First, we summarize the effective strategies used to achieve highly active Pt- and Pd-based catalysts for ethanol electro-oxidation, including composition control, microstructure design, and the optimization of support materials. Second, a few non-precious catalysts based on transition metals (such as Fe, Co, and Ni) are introduced. Finally, we outline the concerns and future development of anode catalysts for DEFCs. This review provides a comprehensive understanding of anode catalysts for ethanol oxidation in DEFCs.
