1Efficient visible light photo-Fenton-like degradation of organic pollutants using in situ surface-modified BiFeO_3 as a catalyst显示文摘The visible light photo-Fenton-like catalytic performance of BiFeO3 nanoparticles was investigated using Methyl Violet(MV),Rhodamine B(RhB) and phenol as probes.Under optimum conditions,the pseudo first-order rate constant(k) was determined to be 2.21 × 102,5.56 × 102 and 2.01 × 102 min 1 for the degradation of MV(30 μmol/L),RhB(10 μmol/L) and phenol(3 mmol/L),respectively,in the BiFeO3-H2O2-visible light(Vis) system.The introduction of visible light irradiation increased the k values of MV,RhB and phenol degradation 3.47,1.95 and 2.07 times in comparison with those in dark.Generally,the k values in the BiFeO3H2O2-Vis system were accelerated by increasing BiFeO3 load and H2O2 concentration,but decreased with increasing initial pollutant concentration.To further enhance the degradation of pollutants at high concentrations,BiFeO3 was modified with the addition of surface modifiers.The addition of ethylenediamineteraacetic acid(EDTA,0.4 mmol/L) increased the k value of MV degradation(60 μmol/L) from 1.01 × 102 min-1 in the BiFeO 3-H2O2-Vis system to 1.30 min-1 in the EDTA-BiFeO3-H2O2-Vis system by a factor of 128.This suggests that in situ surface modification can enable BiFeO3 nano-particles to be a promising visible light photo-Fenton-like catalyst for the degradation of organic pollutants.Junjian An Lihua Zhu Yingying Zhang Heqing Tang 2013Journal of Environmental Sciences2013,25,6:10

3Water Distribution and Removal along the Flow Channel in Proton Exchange Membrane Fuel Cells显示文摘Distribution expressions of total gas pressure and partial water vapor pressure along the channel direction were established based on lumped model by analyzing pressure loss in the channel and gas diffusion in the layer. The mechanism of droplet formation in the flow channel was also analyzed. Effects of the relative humidity, working temperature and stoichiometry on liquid water formation were discussed in detail. Moreover, the force equilibrium equation of the droplet in the flow channel was deduced, and the critical flow velocity for the water droplet removal was also addressed. The experimental results show that the threshold position of the liquid droplet is far from the inlet with the increase of temperature, and it decreases with the increase of the inlet total pressure. The critical flow velocity decreases with the increase of the radius and the working pressure.丁刚强 TANG Heqing LUO Zhiping 涂正凯 PEI Houchang LIU Zhichun LIU Wei 2013Journal of Wuhan University of Technology(Materials Science)2013,28,2:2

5Efficient degradation of drug ibuprofen through catalytic activation of peroxymonosulfate by Fe_3C embedded on carbon显示文摘Ibuprofen(IBU),a nonsteroidal anti-inflammatory drug,is becoming an important member of pharmaceuticals and personal care products(PPCPs)as emerging pollutants.To degrade IBU,magnetic Fe_3C nanoparticles embedded on N-doped carbon(Fe_3C/NC)were prepared as a catalyst by a sol–gel combustion method.As characterized,the Fe_3C/NC nanoparticles were composed of a NC nano-sheet and capsulated Fe_3C particles on the sheet.The Fe_3C/NC nanoparticles were confirmed an efficient catalyst for peroxymonosulfate(PMS)activation to generate sulfate radicals(SO_4^(·-)),single oxygen(~1O_2)and hydroxyl radicals(·OH)toward the degradation of IBU.The added IBU(10 mg/L)was almost completely removed in 30 min by using 0.1 g/L Fe_3C/NC and 2 g/L PMS.The catalyst was confirmed to have good ability and excellent reusability through leaching measurements and cycle experiments.A catalytic mechanism was proposed for the catalytic activation of PMS on Fe_3C/NC,which involves both Fe_3C reactive sites and N-doped carbon matrix as reactive sites in Fe_3C/NC.Moreover,the degradation pathway of IBU in the Fe_3C/NC-PMS system was proposed according to the detections of degradation intermediates.Guangli Zhang Yaobin Ding Wenshan Nie Heqing Tang 2019Journal of Environmental Sciences2019,31,4:2
