| 1 | Roles of various Ni species on TiO2 in enhancing photocatalytic H2 evolution显示文摘Low-cost nickels can be used as cocatalyst to improve the performance of photocatalysts,which may be promising materials applied in the field of photocatalytic water splitting.In this study,different nickel species Ni,Ni(OH)2,NiO,NiOx,and NiS are used to modified titanium dioxide(P25)to investigate their roles on the photocatalytic hydrogen evolution activities.UV-visible,X-ray diffraction(XRD),Brunner-Emmet-Teller(BET)measurements,transmission electron microscopy(TEM),X-ray photoelectron spectroscopy(XPS)analysis etc.are employed to characterize the physical and chemical properties of catalysts.The results indicate that all the nickel species can improve the photocatalytic hydrogen production activity of P25.The P25 modified with NiOx and NiS has more superior photocatalytic hydrogen evolution activities than those modified with other nickel species.The reason for this is that NiOx and NiS can form p-n junctions with P25 respectively.In addition,NiOx can be selectively deposited on the active sites of P25 via in situ the photodeposition method and NiS is beneficial for H+reacting with photo-excited electrons. | Xiaoping CHEN Jihai XIONG Jinming SHI Song XIA Shuanglin GUI Wenfeng SHANGGUAN | 2019 | Frontiers in Energy2019，13，4： | 2 |
| 2 | Control of Copper Pollution in Pig Waste and Recycling of Copper显示文摘With the rapid development of large-scale pig breeding,the problem of environmental pollution around pig farms has become increasingly serious,of which copper pollution has become particularly prominent. Plants such as Leerisia Orygides L.,Eichhornia crassipes( Mart.) Solms,Commelina communis L.,and Rumex acetosa L. that have strong ability to absorb and transform copper can be used to build constructed wetlands to absorb copper in pig waste,and it can be used as a feed additive to be recycled,which can prevent a larger range of pollution caused by the migration and diffusion of copper. | Ao Ziqiang Bu Meihong Peng Guiqun Jiang Cheng Xiong Jihai Gui Shuanglin | 2018 | Meteorological and Environmental Research2018，9，2： | 1 |
| 3 | Recycling of the Waste from Large-scale Pig Farms显示文摘The management mode, economic benefits and technology integration of large-scale pig breeding are superior to those of traditional pig breeding by scattered peasant households, and it has a significant agglomeration effect. However, the waste from large-scale pig farms are discharged in a concentrated manner, which aggravates environmental pollution and increases treatment difficulty, and improper disposal can lead to serious environmental problems. The main pollutants in the waste from large-scale pig farms are high-concentration organic pollutants, nitrogen and phosphorus. Meanwhile, they are also the main nutrients needed for the growth of plants, animals and microorganisms. By a series of key techniques, the waste from large-scale pig farms can be recycled as fertilizer, feed and energy. | Ao Ziqiang Bu Meihong Jiang Cheng Peng Guiqun Gui Shuanglin Fu Jiaqi | 2019 | Meteorological and Environmental Research2019，10，4： | 0 |
| 4 | Anaerobic co-digestion of thermo-alkaline pretreated microalgae and sewage sludge: Methane potential and microbial community显示文摘To improve methane production from sewage sludge(SS),co-digestion of SS and microalgae(MA)was studied and the application of thermo-alkaline pretreatment to MA was evaluated.The results showed that thermo-alkaline pretreatment at 90℃ for 120 min on MA was the optimum pretreatment condition.Furthermore,when the volatile solids(VS)ratio of SS and MA was 1:2,the methane yield reached maximum(368.94 mL/g VS).Fourier transform infrared(FT-IR)and thermogravimetric analysis confirmed the synergetic effects of thermoalkaline pretreated MA on its co-digestion with SS.The analyses of microbial community indicated that Methanobacterium and Methanosarcina were the dominant methanogens during the co-digestion process.However,the relative abundance of Methanosarcina in thermoalkaline pretreated groups was higher compared to unpretreated groups.The microbial community structure might be affected by thermo-alkaline pretreatment rather than by the MA dosage in the co-digestion. | Jiaqi Fu Bing Yan Shuanglin Gui Yinxuan Fu Song Xia | 2023 | Journal of Environmental Sciences2023，，5： | 0 |
| 5 | Disposal of Rural Domestic Sewage in Ecological Wetland System显示文摘Pollution brought by rural domestic sewage has become increasingly serious, so it is imperative to fi gure out economical and efficient solutions. On the basis of comparison between rural domestic sewage treatment means in China and abroad, actual conditions of countryside, current situation and features of domestic sewage, this paper adopted the compound ecological wetland system consisting of anaerobic and aerobic units, ecological floating bed and artifi cial wetland, so as to remove nitrogen and phosphorus efficiently, achieve the goal of low operation and construction cost and less land use. | AO Ziqiang GUI Shuanglin PENG Guiqun XIA Song XIONG Jihai FU Jiaqi JIANG Cheng | 2015 | Journal of Landscape Research2015，7，6： | 0 |
