Lattice oxygen in metal oxides plays an important role the reaction of diesel oxidation catalysts, but atomic-level understanding structural evolution during catalytic process remains elusive. Here, we develop a Mn2O3/SmMn2O5 catalyst using non-stoichiometric exsolution method to explore roles lattice NO oxidation. The enhanced covalency Mn–O bond and increased electron density at Mn3+ sites, induced by interface between exsolved Mn2O3 mullite, lead formation highly active adjacent sites....
Reactivity of OH and hydride species in oxide-catalyzed hydrogenation reactions has attracted great interest. Herein, we report a combined situ spectroscopic characterization density functional theory (DFT) calculation study ceria-catalyzed acetylene semihydrogenation reaction. The ceria surface is fully hydroxylated during the adopted reaction condition. C2H2 adsorbs molecularly on stoichiometric CeO2 hydrogenates with groups selectively to produce C2H4. Semihydrogenation C2H4 either or...
The structure sensitivity of CO2 activation in the presence H2 has been identified by ambient-pressure X-ray photoelectron spectroscopy (APXPS) on Ni(111) and Ni(110) surfaces under identical reaction conditions. Based APXPS results computer simulations, we propose that, around room temperature, hydrogen-assisted is major path Ni(111), while redox pathway prevails Ni(110). With increasing two pathways are activated parallel. While surface fully reduced to metallic state at elevated...
Abstract Selective acetylene hydrogenation is a strongly exothermic process, easy to cause coking and metal agglomeration, thus leads deactivation. In this work, Pd/TiO 2 with different oxygen vacancies (V o ) were synthesized by controlling reduction temperature in 300–700°C, which ‐HT300 (HT temperature) possessed the highest V content. It was found highly dispersed Pd nanoparticles adjacent more exhibited enhanced catalytic behavior (near 100% conversion at 55°C 80% selectivity turnover...
Electrode-electrolyte interface plays a crucial role in determining the stability and behavior of electrochemical electrodes. Although X-ray photoelectron spectroscopy has been established as powerful analytical technique for chemistry, necessity ultrahigh vacuum remains significant obstacle to directly detecting dynamic interfacial evolution, particularly aqueous environments. Here, we employ tender-energy ambient pressure (AP-XPS) bridge gap between near-atmospheric pressure, enabling an...
Abstract Catalyzed sodium borohydride (NaBH 4 ) hydrolysis is integral to H 2 ‐supply systems in fuel cells, with Co‐B among the most effective catalysts featured high B─H bond cleavage activity. However, its limited water dissociation capability produces an insufficient proton supply for generation. In this study, Ru element was introduced of deprotonation into system, constructing a dual‐site catalyst NaBH hydrolysis. A series situ characterizations confirmed accelerated kinetics on...
The nitrogen doping (N-doping) treatment for niobium superconducting radio-frequency (SRF) cavities is one of the key enabling technologies that support development more efficient future large accelerators. However, N-doping results have diverged due to a complex chemical profile under nitrogen-doped surface. Particularly, industrial-scale production conditions, it difficult understand underlying mechanism thus hindering performance improvement. Herein, combination spatially resolved and...
Chronic cholecystitis is a common disease that causes inflammation in the gallbladder and usually associated with gallstones. Laparoscopic cholecystectomy has been widely used as minimally invasive surgical technique to treat this condition. However, clinical effect of laparoscopic treatment chronic gallstones needs further investigation. This study aimed investigate treating 90 patients were randomly divided into control research groups. The group underwent traditional open cholecystectomy,...
The surface structure effect on the oxidation of Cu has been investigated by performing ambient-pressure X-ray photoelectron spectroscopy (APXPS) Cu(111) and Cu(110) surfaces under oxygen pressures ranging from 10-8 to 1 mbar temperatures 300 750 K. APXPS results show a subsequential phase transition chemisorbed O/Cu overlayer Cu2 O then CuO both surfaces. For given temperature, pressure needed induce initial formation is about two orders magnitude greater than that Cu(111), which in...
The interplay between order and disorder is crucial across various fields, especially in understanding oscillatory phenomena. Periodic oscillations are frequently observed heterogeneous catalysis, yet their underlying mechanisms need deeper exploration. Here, we investigate how periodic arise during methane oxidation catalysed by palladium nanoparticles (Pd NPs), utilizing a suite of complementary operando techniques spatial scales. We found that reaction intensity collective dynamic modes...
