论文名称:Unblocked intramolecular charge transfer for enhanced CO2 photoreduction enabled by an imidazolium-based ionic conjugated microporous polymer 发表刊物:Applied Catalysis B: Environmental 刊物所在地:Elsevier 摘要:Efficient solar energy-driven conversion of CO2 to valuable chemicals is challenging. Here we design an imidazolium-based ionic conjugated microporous polymer (ImI-CMP), which unblocks readily intramolecular charge transfer and triggers CO2 photoreduction. Under visible light irradiation, ImI-CMP incorporated with Co (II) species exhibits a high CO production rate of 2953 μmol g−1 h−1 and a turnover frequency of 30.8 h−1; these numbers are competitive to that of the best porous organic polymers. The mechanism studies reveal that two factors play key roles in the outstanding photocatalytic performance. First, the imidazolium motifs on the ImI-CMP enhance the activation of CO2. Second, π-conjugation structure and the built-in electric field allow ultrafast intramolecular photoinduced electron transfer in the ImI-CMP. This work provides a new strategy for designing high-performance organic photocatalysts for CO2 reduction by combining cationic imidazolium motifs and π-conjugation structures. 全部作者:Dong Zhai,Daoyuan Zheng,Hao Wu,Lei Sun,Zhen Li,Tie Yu,Wei Zhou,Xu Fang,Shengliang Zhai,Keli Han,Zuoli He,Weiqiao Deng 第一作者:Wenling Zhao 论文类型:期刊论文 通讯作者:Chengcheng Liu 学科门类:工学 一级学科:环境科学与工程 文献类型:J 卷号:300 页面范围:120719 是否译文:否 发表时间:2022-03-01 收录刊物:SCI 发表时间:2022-03-01
