The rational design and construction of hierarchically porous nanostructure for oxygen reduction reaction (ORR) electrocatalysts is crucial to facilitate the exposure of accessible active sites and promote the mass/electron transfer under the gas-solid-liquid triple-phase condition. Herein, an ingenious method through the pyrolysis of creative polyvinylimidazole coordination with Zn/Fe salt precursors is developed to fabricate hierarchically porous Fe-N-doped carbon framework as efficient ORR electrocatalyst. The volatilization of Zn species combined with the nanoscale Kirkendall effect of Fe dopants during the pyrolysis build the hierarchical micro-, meso-, and macroporous nanostructure with a high specific surface area (1,586 m^(2)·g^(−1)), which provide sufficient exposed active sites and multiscale mass/charge transport channels. The optimized electrocatalyst exhibits superior ORR activity and robust stability in both alkaline and acidic electrolytes. The Zn-air battery fabricated by such attractive electrocatalyst as air cathode displays a higher peak power density than that of Pt/C-based Zn-air battery, suggesting the great potential of this electrocatalyst for Zn-air batteries.

Semihydrogenation plays a key role in industrial hydrorefining of light alkenes, with a market above 400 billion by 2027. The high cost of commercial palladium-based catalysts strongly calls for innovation but with great challenges. Herein, copper nanoparticles decorated with a minimized ppm of Pd are developed through a chemical plating process to integrate the catalytic advantages of copper and palladium for achieving maximized catalysis in the semihydrogenation of a fatal impurity of butadiene in alkene feedstocks. The developed Pd–Cu catalyst (i.e., 114 ppm of Pd in Pd0.0033Cu1/TiO2) exhibits an unprecedented catalytic performance superior to commercial Pd/Al2O3, with 100% butene selectivity above 90% of butadiene conversion over 130 h on stream at 90 °C. Further exploration reveals that the atomically dispersed Pd on Cu nanoparticles, obtained at ultralow ppm levels of Pd loading, induces a hidden but critical H2trap, which concentrates H2on the Pd site for further H2dissociation that offers intermediate hydrogen atoms to the tandem butadiene semihydrogenation over the third layer of Cu atoms neighboring Pd through hydrogen spillover. Moreover, a threshold on Pd density was identified at Pd/Cu surficial atomic ratio of 1/138 (i.e., Pd0.0033Cu1/TiO2) for maximizing butadiene semihydrogenation performance, based on an extreme collaboration between Pd for H2dissociation and Cu for butadiene hydrogenation. This work provides important guidance for developing noble metal-saving catalysts in industrial applications.

Stress corrosion behavior and mechanism of Ti6321 alloy with different microstructures in simulated deep-sea environment

SSRN 2024年

作者： Zhang, Huixia Zhang, Fan Hao, Fuyao Sui, Yongqiang Li, Wenju Li, Xiangbo Hou, Jian Guo, Weimin State Key Laboratory for Marine Corrosion and Protection Qingdao Luoyang Ship Material Research Institute Qingdao China State Key Laboratory of Advanced Technology For Materials Synthesis and Processing Wuhan University of Technology Wuhan430070 China

The stress corrosion cracking (SCC) behaviors of Ti-6Al-3Nb-2Zr-1Mo (Ti6321, in wt.%) alloy samples with equiaxed microstructure (EM), bimodal microstructure (BM) and Widmanstätten microstructure (WM) in simulated 3000m deep sea environment were investigated using electrochemical tests, electron backscattered diffraction (EBSD), and so on. The results revealed that WM exhibits the best SCC resistance, which is attributed to its best self-healing ability, and is beneficial for the re-passivation of fresh metal at the crack tip. Besides, there is no obvious micro-texture region in WM, and α phase colonies hinder the dislocation movement, resulting in the lowest crack growth rate. © 2024, The Authors. All rights reserved.
