| 1 | Coating of Al_2O_3 on layered Li(Mn_(1/3)Ni_(1/3)Co_(1/3))O_2 using CO_2 as green precipitant and their improved electrochemical performance for lithium ion batteries显示文摘Li(Mn1/3Ni1/3Co1/3)O2 cathode materials were fabricated by a hydroxide precursor method.Al2O3 was coated on the surface of the Li(Mn1/3Ni1/3CO1/3)O2 through a simple and effective one-step electrostatic self-assembly method.In the coating process,a NaHCO3-H2CO3 buffer was formed spontaneously when CO2 was introduced into the NaAlO2 solution.Compared with bare Li(Mn1/3Ni1/3Co1/3)O2, the surface-modified samples exhibited better cycling performance,rate capability and rate capability retention.The Al2O3-coated Li(Mn1/3Ni1/3Co1/3)O2 electrodes delivered a discharge capacity of about 115 mAh·g-1 at 2A·g-1,but only 84 mAh·g-1 for the bare one.The capacity retention of the Al2O3-coated Li(Mn1/3Ni1/3Co1/3)O2 was 90.7%after 50 cycles,about 30%higher than that of the pristine one. | Yingqiang Wu Linhai Zhuo Jun Ming Yancun Yu Fengyu Zhao | 2013 | Journal of Energy Chemistry2013，22，3： | 6 |
| 2 | Surface interaction between Pd and nitrogen derived from hyperbranched polyamide towards highly effective formic acid dehydrogenation显示文摘Hydrogen production from formic acid decomposition(FAD)is a promising means of hydrogen energy storage and utilization in fuel cells.Development of efficient catalysts for dehydrogenation of formic acid is a challenging topic.The surface chemical and electronic structure of the active catalysis components is important in formic acid decomposition at room-temperature.Here,the pyrdinic-nitrogen doped catalysts from hyperbranched polyamide were prepared via in situ polymerization reaction process by using activated carbon as a support.Because of the introduction of the polymer,the particles of the catalysts were stabilized,and the average particle diameter was only 1.64 nm.Under mild conditions,the catalysts activities were evaluated for FAD.The optimized Pd-N30/C catalyst exhibited high performance achieving almost full conversion,with a turnover frequency of 3481 h^-1 at 30℃. | Yancun Yu Xian Wang Changpeng Liu Fateev Vladimir Junjie Ge Wei Xing | 2020 | Journal of Energy Chemistry2020，29，1： | 3 |
