1PtxCuy nanocrystals with hexa-pod morphology and their electrocatalytic performances towards oxygen reduction reaction显示文摘二金属的磅 x 有明确的昆虫形态学的 Cu y nanocrystals (NC ) 经由一条湿化学途径被综合。有约 20 nm 表演的尺寸的同样综合的凸的 NC 暴露了低索引(111 ) 种子上的方面和豆荚上的各种各样的高索引的方面。生长机制沿着 cuboctahedral 上的结晶的方向播种的 <100> 包含了比较喜欢的生长。合成协议能被用于磅 x 有各种各样的 Cu/Pt 比率的 Cu y NC。向氧减小反应(ORR ) 在碳黑色上支持的昆虫 PtxCuy NC 的电镀物品催化的活动被学习。昆虫 PtCu 2/C 催化剂展出最高特定的活动(3.7 妈 / 厘米 2) 和集体活动(2.4 A/mg ) 报导了为磅 x Cu y 。有磅 x Cu y 显示提高的活动从词法因素发源。豆荚上的高索引的方面以及丰富的边和步的存在能相当解释提高的催化活动。昆虫磅 x Cu y /C 催化剂也在加速的耐久性测试以后显示出高词法的稳定性和活动。同样综合的昆虫磅 x Cu y NC 为质子交换膜燃料房间作为阴极电镀物品催化剂有高潜力。Yujing Li Fanxin Quan Enbo Zhu Lin Chen Yu Huang Changfeng Chen 2015Nano Research2015,8,10:5
2In situ development of highly concave and compositionconfined PtNi octahedra with high oxygen reduction reaction activity and durability显示文摘有为催化氧减小反应(ORR ) 的唯一的结构的 PtNi 金属 nanocrystals 的控制综合体吸引了大兴趣。这里,我们报导单个水晶的 PtNi octahedra 的一步舞合成与在里面开发 situ 高度为 ORR 是最佳的凹面特征和自我限制的作文。揭示的详细研究充满磅的播种、随后的 Pt/Ni 合作减小,和 PtNi 融合导致了一致单个水晶的 PtNi octahedra,并且 Ni 富有的表面蚀刻的 Ni 方面分离和氧的联合导致了凹度并且限制了 Ni 内容。凹面 PtNi nanocrystals 以两个比商业地可得到的 Pt/C 催化剂展出了高得多的 ORR 性能特定的活动(高 29.1 倍) 并且集体活动(高 12.9 倍) 在 0.9 V (对可逆的氢电极(RHE )) 。没有凹度,表演也比 PtNi octahedra 的高,证实更高的活动是仔细与它的形态学有关。而且,凹面 octahedra 也由于不稳定的地点的钝化在 ORR (在在 0.6 和 1.1 V 对 RHE 之间的 10,000 个周期以后仍然是的 93% 集体活动) 展出了显著稳定性。Enbo Zhu Yongjia Li Chin-Yi Chiu Xiaoqing Huang Mufan Li Zipeng Zhao Yuan Liu Xiangfeng Duan Yu Huang 2016Nano Research2016,9,1:4
3Enhancement of oxygen reduction reaction activity by grain boundaries in platinum nanostructures显示文摘Systematic control of grain boundary densities in various platinum(Pt)nanostructures was achieved by specific peptide-assisted assembly and coagulation of nanocrystals.A positive quadratic correlation was observed between the oxygen reduction reaction(ORR)specific activities of the Pt nanostructures and the grain boundary densities on their surfaces.Compared to commercial Pt/C,the grain-boundary-rich strain-free Pt ultrathin nanoplates demonstrated a 15.5 times higher specific activity and a 13.7 times higher mass activity.Simulation studies suggested that the specific activity of ORR was proportional to the resident number and the resident time of oxygen on the catalyst surface,both of which correlate positively with grain boundary density,leading to improved ORR activities.Enbo Zhu Wang Xue Shiyi Wang Xucheng Yan Jingxuan Zhou Yang Liu Jin Cai Ershuai Liu Qingying Jia Xiangfeng Duan Yujing Li Hendrik Heinz Yu Huang 2020Nano Research2020,13,12:3
4Bridge vibration under complex wind field and corresponding measurements: A review显示文摘Due to increased demands in transportation development,bridge construction has been extended to areas with complex wind fields.In addition to common flow features such as high wind speeds and strong turbulence intensity,in coastal areas,bridges are likely to be exposed to non-stationary and non-Gaussian high-speed wind fields during hurricane events.Bridges built in mountainous regions will experience varying wind directions,incident angles of attack(AOA),and wind speed variation due to undulating terrain.The complex wind fields are challenging to the bridge engineering community to which accurate calculation methods and suppression measures for bridge vibration are urgently required.In this paper,state-of-the-art research results are introduced through three categories:(a)the distinctive characteristics of complex wind fields in offshore and mountainous areas,(b)the categories of wind-induced vibrations for bridges,and(c)the suppression measures employed in engineering practices.Until now,the studies regarding the coupled bridge vibration in complex wind fields have made considerable progress,but a richer database of actual wind measurement results and more efficient simulation methods still need to be further established.Enbo Yu Guoji Xu Yan Han Peng Hu Jamie F.Townsend Yongle Li 2022Journal of Traffic and Transportation Engineering(English Edition)2022,9,3:2
