| 1 | The Study on Application of Bio-enzyme in Dishwasher Detergents显示文摘Aiming at the kitchen stain and fast growth of dishwasher market in China,the addition of protease and amylase solution in the dishwasher detergents was proposed for the food stains typical in China.A comparison between Chinese commercial dishwasher detergents and an EU mainstream detergent was made.The results indicated that the addition of protease and amylase could significantly increase the washing performance,and thus could help close the washing performance gap between our products and the EU mainstream product. | Gao Nan Liu Yitong Tao Ye Wang Jing Qu Xiaoshuang | 2020 | China Detergent & Cosmetics2020，5，2： | 0 |
| 2 | Surface protection method for the magnetic core using covalent organic framework shells and its application in As(Ⅲ)depth removal from acid wastewater显示文摘Fe_(3)O_(4)-based materials are widely used for magnetic separation from wastewater.However,they often suffer from Fe-leaching behavior under acidic conditions,decreasing their ac-tivity and limiting sustainable practical applications.In this study,covalent organic frame-works(COFs)were used as the shell to protect the Fe_(3)O_(4) core,and the Fe_(3)O_(4)@COF core-shell composites were synthesized for As(Ⅲ)removal from acid wastewater.The imine-linked COFs can in situ grow on the surface of the Fe_(3)O_(4) core layer by layer with[COFs/Fe_(3)O_(4)]mol ratio of up to 2∶1.The Fe-leaching behavior was weakened over a wide pH range of 1-13.Moreover,such composites keep their magnetic characteristic,making them favorable for nanomaterial separation.As(Ⅲ)batch adsorption experiments results indicated that,when COFs are used as the shell for the Fe_(3)O_(4) core,a balance between As(Ⅲ)removal efficiencies and the thickness of the COF shell exists.Higher As(Ⅲ)removal efficiencies are obtained when the[COFs/Fe_(3)O_(4)]mol ratios were<1.5∶1,but thicker COF shells were not beneficial for As(Ⅲ)removal.Such composites also exhibited better As(Ⅲ)removal performances in the pH range of 1-7.Over a wide pH range,the zeta potential of Fe_(3)O_(4)@COF core-shell compos-ites becomes more positive,which benefits the capture of negative arsenic ions.In addition,thinner surface COFs were favorable for mass transfer and facilitating the reaction of Fe and As elements.Our study highlights the promise of using COFs in nanomaterial surface protection and achieving As(Ⅲ)depth removal under acidic conditions. | Wenjun Huang Haomiao Xu Xiaoshuang Liu Longlong Wang Shutang Li Leipeng Ji Zan Qu Naiqiang Yan | 2022 | Journal of Environmental Sciences2022，34，5： | 0 |
| 3 | The promoting effect of interstitial hydrogen on the oxygen reduction performance of PtPd alloy nanotubes for fuel cells显示文摘Highly efficient and stable oxygen reduction reaction(ORR)electrocatalysts are remarkably important but challenging for advancing the large-scale commercialization of practical proton exchange membrane fuel cells(PEMFCs).In this work,we report that the introduction of interstitial hydrogen atoms into PtPd nanotubes can significantly promote ORR performance without scarifying the durability.The enhanced mass activity was 8.8 times higher than that of commercial Pt/C.The accelerated durability test showed negligible activity attenuation after 30,000 cycles.Additionally,H2/O2 fuel cell tests further verified the excellent activity of PtPd-H nanotubes with a maximum power density of 1.32 W·cm^(−2),superior to that of commercial Pt/C(1.16 W·cm^(−2)).Density functional theory calculations demonstrated the incorporation of hydrogen atoms gives rise to the broadening of Pt d-band and the downshift of d-band center,which consequently leads to the weaker intermediates binding and enhanced ORR activity. | Tingting Chao Xuan Luo Mengzhao Zhu Yanmin Hu Yida Zhang Yunteng Qu Hantao Peng Xiaoshuang Shen Xusheng Zheng Liang Zhang Xun Hong | 2023 | Nano Research2023，16，2： | 0 |
