A magnetic metal–organic framework-based catalyst CoFe<sub>2</sub>O<sub>4</sub>@SiO<sub>2</sub>@IRMOF-3 was prepared and identified as an efficient for the synthesis of a variety functionalized dihydro-2-oxopyrroles by one-pot, four-component reaction dialkyl acetylenedicarboxylate, aryl amine, formaldehyde, optionally second amine or diamine at room temperature. The magnetically separated recovered without significant loss its catalytic efficiency, even after eight cycles.
In industrial pollutants, phenol is a kind of degradation-resistant hazardous compound. It generated during processes in factories and treatment at sewage plants. this study, we analyse the photocatalytic activity TiO2 rGO as composite for degradation phenol. Hybridised titanium dioxide/reduced graphene oxide (TiO2/rGO) nanocomposites were synthesised by simple hydrothermal method using flake graphite tetrabutyl titanate raw materials. Scanning electron microscopy (SEM), transmission (TEM),...
The source region of the Yangtze River (SRYR) is located in Qinghai-Tibet Plateau, where climatic conditions and alpine-cold natural are harsh. Field investigations hydrochemical characteristics larva juvenile fish rivers SRYR were carried out July 2018 with aim obtaining further information on unique ecological environment status this plateau area. results present research indicated that majority river water quality parameters range class I to II, according classification environmental...
Biological denitrification is still the most important pathway to purifying nitrate-containing wastewater. In this study, pyrite (FeS2 ) and polycaprolactone (PCL) were used as electron donors construct sole or combined systems, that is, pyrite-based autotrophic (PAD) system, PCL-supported heterotrophic (PHD) split-mixotrophic system (combined PAD + PHD), all of which operated under five different hydraulic retention times (HRTs) for 150 days. The results showed removal rates (RE) nitrate...
Many studies have investigated the influence of hydropower stations on macroinvertebrate communities, but few clarified different types stations. A total 133 samples obtained from seven rivers, which 45 are located, with rivers distributed across four provinces (Yunnan, Jiangxi, Fujian, and Hubei) were to study small communities. Samples collected during 2011–2012. Results showed that 126 taxa macroinvertebrates collected, 68.3% insects. The average density biomass 966 ± 112 ind/m2 17.31...
Solid waste red mud was modified by HCl leaching. The structure property and composition of were investigated X-ray diffraction (XRD), fluorescence spectroscopy (XRF), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET). Under UV irradiation, methyl orange (MO) aqueous solution photodegraded mud. obtained results showed that the specific surface area 317.14 m 2 /g, which about 40 times higher than normal After irradiation for 50 min, removal percentage MO reached 94.2%. study...
This work evaluated the effects of inherent alkali and alkaline earth metals on nitrogen transformation during steam gasification Shengli lignite at temperature 873–1173 K in a fluidized-bed/fixed-bed quartz reactor. The results indicated that metal Na Ca, Mg coal have different to NH3, HCN char-N gasification. Specifically lignite, not only catalyze conversions but also promote secondary reactions nascent as well generation NH3 from generated HCN, meanwhile they inhibited conversion char-N....
This article studied pyrolysis characteristics and kinetics of upgraded Yi’an gas coal by low temperature in N2 atmosphere. The quality before after modification was examined thermogravimetric analysis. the becomes violent middle range is calculated to be a third-order reaction. After upgrading, total weight losses caking properties different temperatures increase 250°C best upgrading temperature.
Titanium dioxide (TiO2) nanoparticle in the diameter of 30-50nm this study was prepared by sol-gel method. X-ray diffraction (XRD) and scanning electron microscope (SEM) were employed to investigate characteristics TiO2 nanoparticle. The effect amount distilled water absolute ethyl alcohol, calcination temperature on photocatalytic activity explored degradation phenol. results showed that optimal alcohol 5mL, 90mL 575°C, respectively. Moreover, test, pH value phenol solution discussed. 75mg...
Chinese long flame coal named Naomaohu was pyrolyzed at 600 °C under hydrogen pressures of 0.1–3.0 MPa. The resultant chars were gasified 900 carbon dioxide to illustrate the correlations between structure and reactivity chars. For comparison, experiments same conditions in nitrogen atmosphere also conducted. char yield decreased markedly with increasing pressure, whereas stayed constant regardless being certainly larger than that hydropyrolysis. analyzed by Raman spectroscopy X-ray...
Urban lakes located in densely populated regions are highly vulnerable freshwater ecosystems compared to rural areas due intense anthropogenic activities. However, the impacts of intrinsic lake morphometry on water quality urban remain unclear. In present study, 14 and underlying factors associated with such were explored Wuhan City, China. Of these surveyed lakes, 92.9% eutrophic or hypereutrophic; phytoplankton biomass ranged between 3.2 62.0 mg/L was positively correlated drainage ratio...
Tin thin films were coated on copper substrates using chemical method. specimens under continuously applied compressive and tensile stresses oxidised at 100°C for 8 days. Protrusion whisker growth behaviour of tin was characterised by scanning electron microscope, X-ray diffractometer transmission microscope. The results show that stress would enhance the while reduce growth. A SnO 2 layer formed during oxidation intermetallics Cu 3 Sn 6 5 between substrate, which built up residual in layer....
