| 1 | Hierarchically porous carbon/red phosphorus composite for high-capacity sodium-ion battery anode显示文摘Red phosphorus has received remarkable attention as a promising anode material for sodium ion batteries(NIBs) due to its high theoretical capacity. However, its practical application has been impeded by its intrinsic low electronic conductivity and large volume variations during sodiation/desodiation process. Here, we design a composite to confine nanosized red phosphorus into the hierarchically porous carbon(HPC) walls by a vaporization-condensation strategy. The mass loading of P in the HPC/P composite is optimized to deliver a reversible specific capacity of 2,202 m Ah/gpbased on the mass of red P(836 m Ah/gcompositebased on the total composite mass), a high capacity retention over 77% after100 cycles, and excellent rate performance of 929 m Ah/gpat 2 C. The hierarchical porous carbon serves as the conductive networks, downsize the red phosphorus to nanoscale, and provide free space to accommodate the large volume expansions. The suppressed mechanical failure of the red phosphorus also enhances the stability of solid-electrolyte interface(SEI) layer, which is confirmed by the microscopy and impedance spectroscopy after the cycling tests. Our studies provide a feasible approach for potentially viable high-capacity NIB anode. | Meng Li Na Feng Mengmeng Liu Zifeng Cong Jiangman Sun Chunhua Du Quanbin Liu Xiong Pu Weiguo Hu | 2018 | Science Bulletin2018，63，15： | 5 |
| 2 | Ce(Ⅲ)-modulation over non-enzymatic Pt/CeO_(2)/GO biosensor with outstanding sensitivity and stability for lactic acid detection显示文摘A series of non-enzymatic graphene functionalized biosensors was developed via deposition precipitation method for lactic acid(LA) detection,which we re characterized by transmission electron micro scopy(TEM),Raman spectroscopy,X-ray photoelectron spectroscopy(XPS),gas chromatography-mass spectrometry,liquid chromatography-mass spectro metry,and proton nuclear magnetic re sonance(~1H NMR).The electrochemical performances of the non-enzymatic biosensors were measured by means of the electrochemical impedance spectroscopy(EIS) and cyclic voltammetry(CV) method.The comprehensive analysis of structures shows that Pt,CeO_(2),and GO components interact with each other.During the storing and releasing oxygen,the valence ratio of Ce^(3+)/Ce^(4+) and the number of oxygen vacancies in CeO_(2) change accordingly,which can be conducive to increasing electronic transmission capacity and finally leads to the improvement of electrocatalytic performance.Among them,the Pt/CeO_(2)/GO biosensor containing 0.47 at% platinum exhibits an excellent electrochemical detection performance with high sensitivity of 12.3 μA·L/(mmol·cm^(2)) and a low limit of detection(LOD) of 5.12 μmol/L in a wide linear range from 10 to 900 μmol/L.In addition,the proposed biosensor possesses a promising anti-interference capability,as well as high stability and good reproducibility,which was assessed by testing the cyclic voltammogram in 0.1 mol/L lactic acid one year later.The underlying mechanism was proposed for electrochemical oxidation of LA to carbon dioxide and acetic acid with the synergistic effect among Pt,CeO_(2),and GO.Furthermore,the results of the standard addition method in real samples(human serum and urine samples) reveal that the lactic acid detection of the non-enzymatic Pt/CeO_(2)/GO biosensor is accompanied by high reliability.Thus,it will be a valuable biosensor for in vitro detection of lactic acid level in clinical samples. | Luyao Zhang Fuli Tian Huan Li Jiangman Meng Qi Liu Xiaoqian Guo Yun Qiu Jun Zhang Changyan Li | 2023 | Journal of Rare Earths2023，41，9： | 0 |
