| 1 | Preparation of Multiwall Carbon Nanotubes-supported High Loading Platinum for Vehicular PEMFC Application显示文摘Multiwall carbon nanotube-supported Pt (Pt/MWNTs) catalysts with high dispersion and high loading of Pt were prepared by chemical reduction method and the loading of Pt got to 40 wt%. The average diameter of Pt nanoparticles on MWNTs was about 3.5 nm. When the hydrogen and air were used as reactant gases for PEMFC, Pt/MWNTs catalysts showed significantly higher performance than the Pt/XC-72 (carbon black) catalysts. | Bing ZHANG Li Juan CHEN Kai Yong GE Yah Chuan GUO Bi Xian PENG | 2005 | Chinese Chemical Letters2005，16，11： | 1 |

| 3 | Efficient Small-Molecule Organic Solar Cells by Modulating Fluorine Substitution Position of Donor Material显示文摘Comprehensive Summary The fluorine substitution position in organic semiconductors is critical in improving device performance for organic solar cells(OSCs).Herein,two similar small-molecule donors,B3T-PoF and B3T-PmF,are designed and synthesized,which only differ on the fluorine substitution position on the pendent benzene unit.Although both small-molecule donors exhibit similar absorption profiles and molecular energy levels,B3T-PmF has stronger crystallinity and lower energetic disorder than B3T-PoF.After blending with the non-fullerene acceptor of BO-4Cl,B3T-PmF shows better phase separation and more ordered molecular packing in blend film.As a result,the B3T-PoF:BO-4Cl-based OSC shows a power conversion efficiency(PCE)of 12.3%.In contrast,the B3T-PmF:BO-4Cl-based cell demonstrates obviously increased JSC and FF values,thus yielding an excellent PCE of 14.7%.This study indicates that reasonable selection of fluorine atom substitution position in conjugated side chains is one of the promising strategies for achieving high-performance SM-DSCs. | Tao Zhang Qianglong Lv Zhongxiang Peng Cunbin An Pengqing Bi Ye Xu Ni Yang Jingwen Wang Kaihu Xian Long Ye Shaoqing Zhang Jianhui Hou | 2023 | Chinese Journal of Chemistry2023，41，7： | 0 |
