Surface lattice oxygen is crucial to the degradation of volatile organic compounds (VOCs) over transition metal oxides according Mars-van Krevelen mechanism. Herein, λ-MnO2 in situ grown on surface CoMn spinel was prepared by acid etching corresponding catalysts (CoMn-Hx-Ty) for VOC oxidation. Experimental and relevant theoretical exploration revealed that could decrease electron cloud density around O atom weaken adjacent Mn-O bond due fracture Co-O bond, facilitating transfer subsequently...
Selective catalytic oxidation of NH3 is the most promising method for removing low-concentration NH3. However, achieving high activity and N2 selectivity remains a great challenge. A Ag/CeSnOx tandem catalyst with dual active centers was designed synthesized, which couples over-oxidation on noble metal sites NOx reduction support. The exhibited excellent selective (NH3–SCO) performance at 200–400 °C. Based various characterization techniques DFT calculations, it identified that silver...
Understanding the active sites in catalyst is essential for design of efficient redox catalysis. A series La(1–x)AgxCoO3 (x = 0, 2.5, 5.0, and 7.5%) perovskite catalysts were synthesized by sodium EDTA–citric acid complexation. La97.5Ag2.5CoO3 shows best catalytic activity with solubility range at site, T90, T50, T10 values 448, 358, 302 °C, respectively. Moreover, presence 5% steam, these decreased to 404, 320, 276 H2-TPR O2-TPD characterization confirmed that after site was partially...
Sample morphology is known to have a significant influence on catalytic performance due changes in catalysts' crucial properties such as active sites, oxygen vacancies, and species. It worthwhile revealing the differences catalyst reaction mechanisms for modified catalysts with different morphologies. Herein, MnO2 was grown situ platelike CoAlO (denoted CoAlO-P) flowerlike CoAlO-F) high-efficiency oxidation of volatile organic compounds, which MnO2/CoAlO-P exhibited low T90% 175 °C, good...
Surface hydroxyl groups commonly exist on the catalyst and present a significant role in catalytic reaction. Considering lack of systematical researches effect surface group reactant molecule activation, PtOx/TiO2 PtOx–y(OH)y/TiO2 catalysts were constructed studied for comprehensive understanding roles oxidation volatiles organic compounds. The formed by simple treatment with nitric acid presented greatly enhanced activity toluene which turnover frequency was around 14 times as high that...
The catalytic performance of Zn-based/HZSM-5 catalysts prepared by wet impregnation method was investigated for the methane dehydroaromatization (MDA) reaction under conditions atmospheric pressure and supersonic jet expansion (SJE). physical properties were characterized Brunauer–Emmett–Teller (BET), Fourier transform infrared (FT-IR), temperature-programmed reduction H2 (H2-TPR), desorption NH3 (NH3-TPD), X-ray photoelectron spectroscopy (XPS), thermogravimetric differential (TG/DTG),...

The N2 selectivity of selective catalytic oxidation NH3 (NH3-SCO) at high temperatures is a great challenge. CeSnOx catalysts were synthesized by the coprecipitation method and systematically investigated. exhibited excellent compared to CeO2. possible SCO reaction mechanism synergistic effect over for NH3-SCO performance X-ray photoelectron spectroscopy (XPS) temperature-programmed desorption ammonia (NH3-TPD) characterization manifested that concentrations Oads, Ce3+, acid sites increased....
Highly dispersed ruthenium oxide clusters were synthesized on carbon nanotubes (CNTs) to form RuO2·xH2O/CNT catalyst by a homogeneous oxidation precipitation method. Methanol was carried out at low temperatures for the production of diverse oxygenous products, such as methyl formate (MF) and dimethoxymethane (DMM). Unprecedented conversion rate methanol, high up 545 molMeOH (mol Rusurface)−1 h−1, observed 120 °C. The effect structural water in RuO2 domains performances methanol reaction...
