| 1 | Influence of the structure of TiO_2 , CeO_2 , and CeO_2-TiO_2 supports on the activity of Ru catalysts in the catalytic wet air oxidation of acetic acid显示文摘Ru catalysts, supported on TiO 2 , CeO 2 , and CeO 2 -TiO 2 , were prepared by the impregnation method. The effect of the structure of the supports on the activity of Ru catalysts was investigated in the catalytic wet air oxidation (CWAO) of acetic acid under 230℃ and 5 MPa in a batch reactor. Physical properties including the surface area, crystalline phase, and surface components of the Ru catalysts were characterized by N 2 adsorption, X-ray powder diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). The CeO 2 -based Ru catalysts had good activity, and the prepared RuO 2 /CeO 2 catalyst showed markedly higher activity than the RuO 2 /CeO 2 -TiO 2 catalyst. The surface structure, the high amount of chemisorbed oxygen on the catalyst surface, and the suitable pH pzc value of the supports played an important role in the activity of the Ru catalysts in CWAO of acetic acid. | YANG Shaoxia ZHU Wanpeng WANG Xingang | 2011 | Rare Metals2011，30，5： | 7 |
| 2 | Effects of fulvic acid and humic acid on aluminum speciation in drinking water显示文摘This article focused on the influences of fulvic acid and humic acid on aluminum speciation in drinking water.Factors including the concentration of residual chlorine and pH value had been concerned.Aluminum species investigated in the experiments included inorganic mononuclear,organic mononuclear,mononuclear,polymer,soluble,and suspended forms.It was found that the effects of fulvic acid and humic acid on aluminum speciation depended mainly on their molecular weight.Fulvic acid with molecular weight less than 5000 Dalton had little influence on aluminum speciation;while fulvic acid with molecular weight larger than 5000 Dalton and humic acid would increase the concentration of soluble aluminum significantly even at concentration below 0.5 mg/L(calculated as TOC).Aluminum species,in the present of fulvic acid with molecular weight larger than 5000 Dalton and humic acid,were more stable than that in the present of fluvic acid with molecular mass less than 5000 Dalton,and varied little with reaction time.Within pH range 6.5-7.5,soluble aluminum increased notably in water with organic matter.As the concentration of residual chlorine increased,the effects of fulvic acid and humic acid became weak.The reactions between humic acid,fulvic acid with large molecular weight,and aluminum were considered to be a multi-dentate coordination process.With the consideration of aluminum bioavailability,reducing the concentration of fulvic acid and humic acid and keeping the pH value among 6.5-7.5 were recommended during drinking water treatment. | Wendong Wang Hongwei Yang Xiaochang Wang Jing Jiang Wanpeng Zhu | 2010 | Journal of Environmental Sciences2010，22，2： | 6 |
| 3 | Catalytic wet air oxidation of phenol with functionalized carbon materials as catalysts:Reaction mechanism and pathway显示文摘The development of highly active carbon material catalysts in catalytic wet air oxidation(CWAO)has attracted a great deal of attention. In this study different carbon material catalysts(multi-walled carbon nanotubes,carbon fibers and graphite) were developed to enhance the CWAO of phenol in aqueous solution. The functionalized carbon materials exhibited excellent catalytic activity in the CWAO of phenol. After 60 min reaction,the removal of phenol was nearly100% over the functionalized multi-walled carbon,while it was only 14% over the purified multi-walled carbon under the same reaction conditions. Carboxylic acid groups introduced on the surface of the functionalized carbon materials play an important role in the catalytic activity in CWAO. They can promote the production of free radicals,which act as strong oxidants in CWAO. Based on the analysis of the intermediates produced in the CWAO reactions,a new reaction pathway for the CWAO of phenol was proposed in this study. There are some differences between the proposed reaction pathway and that reported in the literature. First,maleic acid is transformed directly into malonic acid. Second,acetic acid is oxidized into an unknown intermediate,which is then oxidized into CO2 and H2O. Finally,formic acid and oxalic acid can mutually interconvert when conditions are favorable. | Jianbing Wang Wantao Fu Xuwen He Shaoxia Yang Wanpeng Zhu | 2014 | Journal of Environmental Sciences2014，26，8： | 6 |
| 4 | Factors effecting aluminum speciation in drinking waterby laboratory research显示文摘Effects of aluminum on water distribution system and human health mainly attribute to its speciation in drinking water. Laboratory experiments were performed to investigate factors that may influence aluminum speciation in water supply system. The concentration of soluble aluminum and its transformation among other aluminum species were mainly controlled by kinetics processes of related reactions. Total aluminum concentration had a notable effect on the concentrations of mononuclear and soluble aluminum in the first 4 day; then its e?ect became weak. At pH above 7.50, both fluoride and orthophosphate had little effect on aluminum speciation; while, when the solution pH was below 7.50, the concentrations of mononuclear and soluble aluminum were proportional to the concentration of fluoride and inversely proportional to the concentration of orthophosphate. Both mononuclear and polynuclear silicic acids could complex with mononuclear aluminum by forming soluble aluminosilicates. In addition, the adding sequence of orthophosphate and aluminum into drinking water would also affect the distribution of aluminum species in the first 4 day. In order to minimize aluminum bioavailability in drinking water, it was suggested that orthophosphate should be added prior to coagulant process, and that the concentrations of fluoride and silicic acids should be controlled below 2.0 and 25 mg/L, respectively, prior to the treatment. The solution pH in coagulation and filtration processes should be controlled in the range of 6.50-7.50. | WendongWang Hongwei Yang Xiaochang Wang Jing Jiang Wanpeng Zhu | 2010 | Journal of Environmental Sciences2010，22，1： | 4 |

| 6 | Effect of interstitial carbon and nitrogen on corrosion of FeCoCrNi multi-principal element alloys made by selective laser melting显示文摘The corrosion behaviors of selective laser melted(SLMed)FeCoCrNi multi-principal element alloys(MPEAs)with carbon or nitrogen addition in 0.5 M H_(2)SO_(4) solution were investigated.Both C and N ad-dition refined the grains and introduced a heterogeneous structure in SLMed FeCoCrNi MPEA,but they had opposite effects on the corrosion behavior.The doped carbon participated as nano-sized carbides in SLMed MPEA,and localized galvanic corrosion occurred,degrading the corrosion resistance.The doped nitrogen was gathered with chromium and formed CrN chemical clusters in SLMed MPEA,and a protec-tive passive film with a higher Cr_(2)O_(3)/Cr(OH)_(3) ratio formed,which improved corrosion resistance. | Wenyu Chen Rui Zhou Wanpeng Li Yen-Hsiang Chen Tzu-Hsiu Chou Xu Wang Yong Liu Yuntian Zhu J.C.Huang | 2023 | Journal of Materials Science & Technology2023，，17： | 2 |
