Industrial-use catalysts usually encounter severe deactivation after long-term operation for catalytic oxidation of chlorinate volatile organic compounds (CVOCs), which becomes a "bottleneck" large-scale application combustion technology. In this work, typical acidic solid-supported MnxCe1-xO2/HZSM-5 were investigated the chlorobenzene (CB). The activation energy (Ea), Brønsted and Lewis acidities, CB adsorption behaviors, stabilities, surficial accumulation (after aging) studied using range...
Manganese-based catalysts have shown excellent low-temperature selective catalytic reduction (SCR) activity for NOx removal. However, they would always produce a high amount of more toxic byproduct, N2O. Ca modification has been reported to be able promote N2 selectivity SCR catalysts, but the mechanism is still not clear. In this study, series Ca-modified Ce0.02Mn0.4/TiO2 were utilized study. terms DRIFT analysis, addition had significantly reduced formation NH on catalyst surface, which...
In this article, the underlying effect of phosphoric acid etching and additional water vapor on chlorine desorption behavior over a model catalyst La3Mn2O7 was explored. Acid treatment led to formation LaPO4 enhanced mobility lattice oxygen evidenced by range characterization (i.e., X-ray diffraction, temperature-programmed analyses, NH3–IR, etc.). The former introduced thermally stable Brönsted acidic sites that dichloromethane (DCM) hydrolysis while latter facilitated accumulated at...
Defect engineering can create various vacancy configurations in catalysts by finely tuning the local electronic and geometric structures of active sites. However, achieving precise control identification these defects remains a significant challenge, origin catalysts, especially clustered or associated ones, largely unknown. Herein, we successfully achieve controllable fabrication quantitative triple O-Ti-O associate (VOVTiVO) nanosized Ni-doped TiO2. Experimental theoretical analyses...
The synergistic control of multipollutants is the frontier environmental catalysis. This research in infancy stage, and many uncertainties still remain. Herein, we investigated reaction characteristics elimination NOx chloroaromatics on a commercial V2O5–WO3/TiO2 catalyst. byproducts were qualitatively quantitatively analyzed, their origins clarified. In particular, polychlorinated dibenzo-p-dioxins (PCDDs) dibenzofurans (PCDFs) from with or without SO2 first explored; this crucial for...
In this paper, we investigated the primary reduction and oxygen replenishing processes over Mn substitutionally doped CeO2(111) surfaces by density functional theory with on-site Coulomb correction (DFT + U). The results indicated that doping could make surface much more reducible adsorbed O2 be effectively activated to form superoxo (O2−) and/or peroxo species (O22−). induced 3d–O 2p gap state instead of Ce 4f acting as an electrons acceptor donor during first vacancy formation...
In this paper, the poisoning effect of alkali and alkaline earth metal on Ce/TiO2 catalysts was investigated for first time a deactivation mechanism proposed. The catalyst observed to be deactivated seriously by loading Na+, K+ or Ca2+ ions. When Na/Ce, K/Ce Ca/Ce molar ratio exceeded 0.25, NO conversion at 380 °C decreased from 78% negligibly low. After subjecting it range analytical techniques, including X-ray diffraction (XRD), photoelectron spectroscopy (XPS), transmission electron...
The development of efficient technologies to prevent the emission hazardous chlorinated organics from industrial sources without forming harmful byproducts, such as dioxins, is a major challenge in environmental chemistry. Herein, we report new hydrolytic destruction route for elimination and demonstrate that phosphoric acid-modified CeO2 (HP-CeO2) can decompose chlorobenzene (CB) polychlorinated congeners under industry-relevant reaction conditions. active site pathway were investigated, it...
Industrial combustion of chloroaromatics is likely to generate unintentional biphenyls (PCBs), polychlorinated dibenzo- p-dioxins (PCDDs), and dibenzofurans (PCDFs). This process involves a surface-mediated reaction can be accelerated in the presence catalyst. In past decade, effect surface nature applied catalysts on conversion PCBs/PCDD/PCDF has been well explored. However, studies how flue gas interferent components affect such remain insufficient. this article, critical component, alkali...
Layered perovskites possess frameworks that can sustain a larger extent of oxygen nonstoichiometry than perovskites, which makes them possibly more suitable for catalytic applications. However, there is little work in literature concerning the behaviors them. In this paper, Lan+1NinO3n+1 layered were selected as potential catalysts oxidation toluene and methane. The activation transmission active species over structure explored by using range analytical techniques, e.g., O2-TPD, XPS, H2-TPR....
Municipal solid waste incineration and the iron steel smelting industry can simultaneously discharge NOx chlorinated organics, particularly polychlorinated dibenzo-p-dioxins dibenzofurans (PCDD/Fs). Synergistic control of these pollutants has been considered among most cost-effective methods. This work combined experimental computational methods to investigate reaction characteristics a catalytically synergistic approach gives first insight into effect arsenic (As) on multipollutant...
