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.

Rational design of hierarchically porous Fe-N-doped carbon as efficient electrocatalyst for oxygen reduction reaction and Zn-air batteries

引用

Nano Research 2021年第12期14卷 4768-4775页

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.
