“…68 Resulting octahedral Pt 3 Ni/C and Pt 1.5 Ni/C had different particle sizes ranging from about 4 to 8 nm. The different sizes led to the change in the fraction of (111) terraces (panels e and f of Figure 3), attributed to the increase in the ORR activity.…”

“…DFT results suggested that the presence of the oxygen vacancies contributed to accelerating the whole ORR process, which was consistent with the experimental results (panels e and f of Figure ). On the other hand, proton exchange membrane fuel cells (PEMFCs) have been regarded as a green alternative to fossil fuel, and facilitating the ORR kinetics in an acid electrolyte plays a critical role in enhancing the cell performance. , Accordingly, 3d metals have also been applied for acid ORR. For example, Mu et al synthesized Fe 2 P nanoparticles embed in Fe–N–P co-doped carbon nanotubes by the decomposition of a mixture of ZIF-8 and LiFePO 4 , which served as the carbon substrate and Fe and P sources, respectively .…”

The rapidly increasing demand for clean and efficient energy devices is a critical issue for the sustainable development of human society. The green and low-cost aqueous zinc–air batteries (ZABs) with high theoretical energy density are therefore drawing increasing attention. As the key materials in the air cathode, electrocatalysts that catalyze the oxygen evolution/reaction reactions (OER and ORR) significantly determine the performance of ZABs. Therefore, exploring economic and efficient oxygen catalysts is of great importance for the practical application of ZABs. Among the numerous electrocatalysts, the earth-abundant 3d transition-metal-based nanomaterials have been widely explored as a result of their low cost and high activities. This review introduces some typical and recent progresses in 3d metal-based oxygen catalysts (i.e., metals, metal compounds, and carbon-supported hybrids) for ZABs. Especially, the active sites for catalyzing OER/ORR of different catalysts are classified, and the strategies for regulating the catalytic sites and their reaction mechanism are also introduced. In the end, the challenges and perspectives for further developing 3d metal-based oxygen catalysts are briefly discussed. This review aims to provide inspirations for the exploration of low-cost and efficient electrocatalysts as cathodes for ZABs.

Direct glycerol fuel cell (DGFCs) is an interesting type of fuel cell that can produce energy and high-end chemicals using excess and less expensive fuel, glycerol. The commercialization of DGFCs meets with many challenges, especially on its catalyst development. Common catalysts usually tested in DGFCs are platinum-based (Pt) and palladium-based catalyst (Pd). The expensive value of the noble metal such as Pt and Pd becomes a limitation towards the commercialization. This review shows and summarizes numerous improvements achieved on the anode catalyst for GOR to reduce the noble metal dependency while maximizing the activity performance, durability-stability, and GOR yield selectivity on certain valuable chemicals introducing multiple optimized syntheses methods with timesaving and cost-effective benefits. Finally, this review proposes the next direction of catalyst development to be taken in the future based on the recent developments and innovations implemented and tested.

With the deterioration of the ecological environment and the depletion of fossil energy, fuel cells, representing a new generation of clean energy, have received widespread attention. This review summarized recent progress in noble metal-based core–shell catalysts for oxygen reduction reactions (ORRs) in proton exchange membrane fuel cells (PEMFCs). The novel testing methods, performance evaluation parameters and research methods of ORR were briefly introduced. The effects of the preparation method, temperature, kinds of doping elements and the number of shell layers on the ORR performances of noble metal-based core–shell catalysts were highlighted. The difficulties of mass production and the high cost of noble metal-based core–shell nanostructured ORR catalysts were also summarized. Thus, in order to promote the commercialization of noble metal-based core–shell catalysts, research directions and prospects on the further development of high performance ORR catalysts with simple synthesis and low cost are presented.
