Enhancing the intrinsic activity and space time yield of Cu based heterogeneous methanol synthesis catalysts through CO2 hydrogenation is one major topics in conversion into value-added liquid fuels chemicals. Here we report inverse ZrO2/Cu with a tunable Zr/Cu ratio have been prepared via an oxalate co-precipitation method, showing excellent performance for to methanol. Under optimal condition, catalyst composed by 10% ZrO2 supported over 90% exhibits highest mass-specific formation rate...
Abstract. Air quality models have not been able to reproduce the magnitude of observed concentrations fine particulate matter (PM2.5) during wintertime Chinese haze events. The discrepancy has at least partly attributed low biases in modeled sulfate production rates, due lack heterogeneous on aerosols models. In this study, we explicitly implement four formation mechanisms into a regional chemical transport model, addition gas-phase and in-cloud production. We compare model results with...
Single-atom catalysts (SACs) have attracted broad interest recently due to their superior catalytic properties. However, a facile fabrication method for the large-scale synthesis of SACs is still in demand. This study reports mechanochemical approach mass production noble metal SACs. The successful formation atomically dispersed palladium species on zinc oxide (Pd1/ZnO) was verified by aberration-corrected high-angle annular dark-field scanning transmission electron microscopy and X-ray...
Organic peroxy radicals (RO 2 ) are key intermediates in the atmospheric degradation of organic matter and fuel combustion, but to date, few direct studies specific RO complex reaction systems exist, leading large gaps our understanding their fate. We show, using direct, speciated measurements a suite gas-phase dimers from O 3 -initiated oxidation α-pinene, that ∼150 gaseous (C 16–20 H 24–34 4–13 primarily formed through cross-reactions, with typical rate constant 0.75–2 × 10 −12 cm molecule...
Acid-driven multiphase chemistry of isoprene epoxydiols (IEPOX), key oxidation products, with inorganic sulfate aerosol yields substantial amounts secondary organic (SOA) through the formation organosulfur compounds. The extent and implications inorganic-to-organic conversion, however, are unknown. In this article, we demonstrate that extensive consumption occurs, which increases IEPOX-to-inorganic concentration ratio (IEPOX/Sulfinorg), as determined by laboratory measurements....
Atmospheric oxidation of natural and anthropogenic volatile organic compounds (VOCs) leads to secondary aerosol (SOA), which constitutes a major often dominant component atmospheric fine particulate matter (PM2.5). Recent work demonstrates that rapid autoxidation peroxy radicals (RO2) formed during VOC results in highly oxygenated molecules (HOM) efficiently form SOA. As NOx emissions decrease, the chemical regime atmosphere changes one RO2 becomes increasingly important, potentially...
Abstract Semi-hydrogenation of acetylene in excess ethylene is a key industrial process for purification. Supported Pd catalysts have attracted most attention due to their superior intrinsic activity but often suffer from low selectivity. single-atom (SACs) are promising significantly improve the selectivity, needs be improved and feasible preparation SACs remains grand challenge. Here, we report simple strategy construct 1 /TiO 2 by selectively encapsulating co-existed small amount...
Abstract The coordination microenvironment of metal active sites in metal–organic frameworks (MOFs) plays a crucial role its performance for electrochemical CO 2 reduction reaction (CO RR). However, it remains challenge to clarify the structure–performance relationship RR catalyzed by MOFs. Herein, series MOFs with different microenvironments Cu(I) (CuCl, CuBr, and CuI) evaluate their performances is synthesized. With increasing radius halogen atom, adsorption capacity increases d‐band...
Abstract 3D flowerlike Pt nanoparticle clusters are electrodeposited onto multiwalled carbon nanotubes (MWCNTs) by using a three‐step protocol, which is all‐electrochemical and involves key, second step of potential pulse sequence. This fractal morphology in marked contrast to the 2D uniform dispersion MWCNTs, achieved when adopts cyclic voltammetry instead potential‐step method. The former found exhibit significantly higher electrocatalytic activity better stability than latter for...
Sulfide oxidation is coupled with electricity generation in a sulfide-fed microbial fuel cell (MFC). This study demonstrated that both electrochemical reactions and catalysis were involved such complex sulfide process the anode of an MFC. The microbe-assisted generated higher persistent current density than via single only. Three valence states S (−II), (0), (+VI) discovered from oxidation, S0, Sx2−, S4O62−, S2O32−, SO42− detected as intermediates. Based on sulfur speciation community...
Heterogeneous reaction of SO2 on mineral dust seems to be an important sink for SO2. However, kinetic data about this authentic are scarce and mainly limited low relative humidity (RH) conditions. In addition, little is known the role hydrogen peroxide (H2O2) in reaction. Here, we investigated uptake kinetics three dusts (i.e., Asian (AMD), Tengger desert (TDD), Arizona test (ATD)) absence presence H2O2 at different RHs using a filter-based flow reactor, applied parameter (effectiveness...
Transition-metal sulfide SnS2 has aroused wide concern due to its high capacity and nanosheet structure, making it an attractive choice as the anode material in sodium-ion batteries. However, large volume expansion poor conductivity of lead inferior cycle stability well rate performance. In this work, FeS2 was situ introduced synchronously grow with on rGO prepare a heterojunction bimetallic SnS2/FeS2/rGO composite. The composition distinctive structure facilitate rapid diffusion Na+ improve...

Abstract. Organosulfates (OSs) are ubiquitous in the atmosphere and serve as important tracers for secondary organic aerosols (SOAs). Despite intense research over years, abundance, origin, formation mechanisms of OSs ambient aerosols, particularly regions with severe anthropogenic pollution, still not well understood. In this study, we collected filter samples fine particulate matter (PM2.5) four seasons both 2015–2016 2018–2019 at an urban site Shanghai, China, comprehensively...
Abstract. Nitrate aerosol plays an increasingly important role in wintertime haze pollution China. Despite intensive research on nitrate chemistry recent years, quantitative constraints the formation mechanisms of Yangtze River Delta (YRD), one most developed and densely populated regions eastern China, remain inadequate. In this study, we identify major pathways their key controlling factors during winter period YRD using 2-year (2018–2019) field observations detailed...
