| 1 | 石墨烯纳米片对电极染料敏化太阳电池显示文摘将经球磨处理的鳞片石墨作为前驱体采用氧化还原法制备石墨烯纳米片(GNs),考察晶体结构变化。将GNs作为催化材料应用于染料敏化太阳电池(DSCs),探讨GNs对电极经热处理对器件光电性能的影响。结果表明,采用球磨对鳞片石墨进行预处理,能改进GNs的晶体结构,即厚度减薄、晶面间距d(002)增大。晶体结构改进后的GNs具有更高的催化活性和更强的氧化还原对扩散能力,相应地,DSCs的转换效率得到大幅度的提升。GNs对电极经热处理,能进一步提高对电极的催化活性以及氧化还原对扩散能力,最终促使器件的转换效率从1.17%增加到1.54%,增幅达到31.3%。 | 徐顺建 罗玉峰 钟炜 肖宗湖 罗永平 | 2013 | 光学学报2013，33，10： | 5 |

| 3 | N-doped porous graphene for carbon dioxide separation:a molecular dynamics study显示文摘Using molecular dynamics simulations,it is shown that N-doped porous graphene membrane can efficiently separate CO2from the CO2/CH4mixture.The effects of pore rim modifications,N-doping sites,initial gas pressure,and feed gas compositions on CO2separation performance of N-doped porous graphene membrane are also examined.It is found that gas permeability increases with increasing initial gas pressure or the feed gas percentages.Pore rim modifications with nitrogen atoms(pyridinic N)can significantly improve the selectivity of CO2over CH4owing to the enhanced electrostatic interactions compared to the unmodified one,and the all-N-modified pore-16 shows the highest CO2selectivity over CH4(*29).Doping N atoms on the graphene sheets(quaternary N)has little effect on the CO2selectivity.Our study demonstrates that the N-doped porous graphene is an excellent candidate for CO2separation,which may be beneficial for the realization of a low carbon society. | Qingzhong Xue Meixia Shan Yehan Tao Zilong Liu Cuicui Ling Yonggang Du | 2014 | Chinese Science Bulletin2014，59，29： | 3 |

| 7 | The structural changes of blood pyropolymers and their beneficial electrocatalytic activity toward oxygen reduction显示文摘There is a growing interest in designing more effective fuel cell cathode catalyst precursors.Here the partial pyrolysis of animal bloods has been used to produce the blood pyropolymers,which are an intermediate substance between a polymer and carbonaceous material.These pyropolymers were yielded by carbonization process below 600°C.The structural changes in the pyropolymers were characterized by X-ray diffraction,and their formation was checked by micro-IR spectra,thermogravimetric and differential thermal analysis.Their potential electrocatalytic properties were evaluated using the linear sweep voltammetry in the O2-saturated KOH solution.It is found that the process of pyropolymer formation began about 200°C and completed around500°C.The change of particle phase depends on the formation of the pyropolymers,but has no effect to their internal carbon structures which are controlled by pyrolysis process only.Meanwhile,it is confirmed that the crystalline phases in the pyropolymers can exist at the surface of heat-treated materials.It can be also found that the carbon materials are active toward oxygen reduction and their activity is associated with the carbonization level.Our study will stimulate the designers to design the highly active catalysts by using native blood pyropolymers as the precursors. | GUO ChaoZhong CHEN ChangGuo LUO ZhongLi | 2013 | Chinese Science Bulletin2013，58，30： | 1 |
