Abstract For the large-scale sustainable implementation of polymer electrolyte membrane fuel cells in vehicles, high-performance electrocatalysts with low platinum consumption are desirable for use as cathode material during oxygen reduction reaction cells. Here we report a carbon black-supported cost-effective, efficient and durable single-atom electrocatalyst monoxide/methanol tolerance cathodic reaction. The acidic single-cell such catalyst delivers high performance, power density up to...
In this article, manganese oxide nanorods with different crystalline structures, i.e., β-MnO2, α-Mn2O3, and a composite of Mn3O4 were successfully synthesized via controlling the heat-treatment procedure starting from composite, containing γ-MnOOH Mn(OH)4. The oxygen reduction reaction (ORR) polarization curves measured by rotating disk electrode (RDE) setup show that those MnOx catalysts higher Mn valent states, Mn(OH)4 exhibit better catalytic activity toward ORR than lower valences....
Maximizing the platinum utilization in electrocatalysts toward oxygen reduction reaction (ORR) is very desirable for large-scale sustainable application of Pt energy systems. A cost-effective carbon-supported carbon-defect-anchored single-atom (Pt1 /C) with remarkable ORR performance reported. An acidic H2 /O2 single cell Pt1 /C as cathode delivers a maximum power density 520 mW cm-2 at 80 °C, corresponding to superhigh 0.09 gPt kW-1 . Further physical characterization and functional theory...
A real optimal Fe content: For N and co-doped carbon electrocatalysts for oxygen reduction reactions (ORRs) it is found that there a trace content (Peak II), which has never been observed before. The electrocatalyst shows superior high activity ORR possesses the best price/performance ratio ever. As service to our authors readers, this journal provides supporting information supplied by authors. Such materials are peer reviewed may be re-organized online delivery, but not copy-edited or...
Proton exchange membrane fuel cells (PEMFCs) have been widely acknowledged as a significant advancement in achieving sustainable energy conversion. However, the activation of newly established Pt-ionomer interfaces catalyst layer PEMFCs can be time-consuming and costly process to ensure proper coupling performance. In order gain valuable insights into this crucial process, we conducted comprehensive analysis comparison commonly employed on-line (such current or voltage control activation,...

Exploring highly efficient platinum single-atom (Pt1) catalysts for oxygen reduction reaction (ORR) is desired to greatly reduce the costs of polymer electrolyte membrane (PEM) fuel cells. Herein, based on a nitrogen-doped active carbon (N-doped Black Pearl, NBP), an atomically dispersed Pt-based electrocatalyst first prepared via hydrothermal ethanol method with Pt content about 5 wt % (Pt1/NBP), and it shows high selectivity two-electron pathway. Through further high-temperature pyrolysis,...
Abstract Maximizing the platinum utilization in electrocatalysts toward oxygen reduction reaction (ORR) is very desirable for large‐scale sustainable application of Pt energy systems.

Transport highways in electrode, significantly improve transport liquid/gas, ions, electron anode, resulting a high...
Severe capacity/voltage fading still poses substantial obstacles in the commercial applications of Li-rich layered oxides, which stems from aggregation Li2MnO3-like domains and unstable surface structure. Here, we report highly stabilized Co-free Li1.2Ni0.2Mn0.6O2 with uniformly dispersed a protective rock-salt structure shell by reducing oxygen partial pressure during high-temperature calcination. Experimental characterizations DFT calculations reveal that small-sized suppress peroxidation...
