Tuning the interaction between loaded metal oxide and support material is an efficient strategy to boost catalytic purification of ammonia (NH3) as important factor in formation haze. Herein, CuO/CeO2 catalysts based on ceria shape effect (Ce-NR Ce-NC) are prepared tested for selective oxidation (NH3-SCO). The CuO CeO2 with different shapes crucial regulate interface structure content oxygen vacancies. Cu/Ce-NR possesses more Cu+-Ov-Ce3+ interfacial sites vacancies achieves a higher activity...
Tuning the oxygen species activity of transition metal oxide catalysts is essential for harnessing environmental catalytic oxidation reactions, and mobility lattice activation ability gas over CoMn2O4 were well modulated by in situ solvothermal-induced lanthanum doping VOCs oxidation. Lanthanum successfully doped into spinel lattice, toluene rate Co1Mn1.9La0.1 increased 20.74 times compared with that undoped Co1Mn2 catalyst at 220 °C. With doping, content vacancies was remarkably (1.4-fold)...
The in-depth activation mechanism of oxygen species (including lattice and gaseous oxygen) for catalytic oxidation reactions has not been elucidated still remains a question on the experimental level. In this work, dual molecule highly efficient volatile organic compound was observed spinel catalysts through construction vacancy engineering (urea modification). active surface were generated via weakening metal–oxygen bond strength, which could be easily activated to participate in toluene...
Highly dispersed Fe<sub>2</sub>O<sub>3</sub> nanoparticles supported on CNTs showed excellent NO conversion, selectivity and durability towards SO<sub>2</sub>/H<sub>2</sub>O at low temperatures (200–325 °C).
Bifunctional zeolite-Ag catalysts with a tandem process offer versatile pathway for efficient HCHO removal at low temperature. The overall performance of systems is highly sensitive to the tunable nature Ag component. Herein, we report ZSM-5||Ag/γ-Al2O3 catalyst that exhibits superior low-temperature activity compared ZSM-5||Ag/SiO2 catalyst, achieving 100% conversion 55 °C versus 32% latter. This dramatic improvement attributed morphological variations induced by differences in mobility and...
Benzene dye intermediates (BDI) wastewater has caused major environmental concern due to its potential carcinogenic, teratogenic, and mutagenic effects.
We demonstrate a new material by intercalating Mo3 S132- into Mg/Al layered double hydroxide (abbr. S13 -LDH), exhibiting excellent capture capability for toxic Hg2+ and noble metal silver (Ag). The as-prepared -LDH displays ultra-high selectivity of Ag+ , Cu2+ in the presence various competitive ions, with order >Hg2+ >Cu2+ >Pb2+ ≥Co2+ Ni2+ Zn2+ Cd2+ . For extremely fast adsorption rates (≈90 % within 10 min, >99 1 h) are observed. Much high is present especially trace amounts (≈1 ppm),...
In contrast to numerous studies on oxygen species, the interaction of volatile organic compounds (VOCs) with oxides is also critical catalytic reaction but has hardly been considered. Herein, we develop a highly efficient Pt atom doped spinel CoMn2O4 (Pt-CoMn) for oxidation toluene at low temperature, and conversion rate increased by 18.3 times (129.7 versus 7.1 × 10–11 mol/(m2·s)) 160 °C compared that CoMn2O4. Detailed characterizations density functional theory calculations reveal local...
This paper presents a new approach to tune the de/hydriding thermodynamic properties of Mg via forming reversible base solid solutions in Mg–In and Mg–In–Al systems by mechanical milling. The effect solubility In Al on formation solution structure hydrogen storage were investigated. It is found that although solute atoms unavoidably are rejected upon hydriding, hydrogenated products MgH2 intermediate MgIn compound could fully transform back after dehydrogenation. hydriding Mg(In, Al) ternary...
Density functional theory (DFT) calculations combined with microkinetic analysis were performed to study the behavior of ammonia on clean, oxygen- and hydroxyl-predosed Ir(100). It is shown that predosed oxygen or hydroxyl promotes NH3 NH dehydrogenation steps, while NH2 slightly inhibited relative clean In both cases, hydrogen transfer from NHx species O OH favored over thermal decomposition NHx. Furthermore, exhibits higher activity steps than OH, case reversed for NH2. On Ir(100), N +...
Cubic cuprous oxide is applied in the selective catalytic oxidation of ammonia to nitrogen (NH3-SCO) investigate effect structure evolution on performance. Different structures (Cu2O, Cu2O–CuO, and CuO) that formed progressively during reconstruction process with time are discovered by X-ray diffraction (XRD), photoelectron spectroscopy (XPS), other characterization methods. The optimal CuO–Cu2O exhibits best performance, which has T100% = 210 °C above 80% N2 selectivity. Combining...
