Exclusive responsiveness to ultraviolet light (~3.2 eV) and high photogenerated charge recombination rate are the two primary drawbacks of pure TiO_(2). We combined N-doped graphene quantum dots (N-GQDs), morphology regulation, and heterojunction construction strategies to synthesize N-GQD/N-doped TiO_(2)/P-doped porous hollow g-C_(3)N_(4) nanotube (PCN) composite photocatalysts (denoted as G-TPCN). The optimal sample (G-TPCN doped with 0.1wt% N-GQD, denoted as 0.1% G-TPCN) exhibits significantly enhanced photoabsorption, which is attributed to the change in bandgap caused by elemental doping (P and N), the improved light-harvesting resulting from the tube structure, and the upconversion effect of N-GQDs. In addition, the internal charge separation and transfer capability of0.1% G-TPCN are dramatically boosted, and its carrier concentration is 3.7, 2.3, and 1.9 times that of N-TiO_(2), PCN, and N-TiO_(2)/PCN(TPCN-1), respectively. This phenomenon is attributed to the formation of Z-scheme heterojunction between N-TiO_(2) and PCNs, the excellent electron conduction ability of N-GQDs, and the short transfer distance caused by the porous nanotube structure. Compared with those of N-TiO_(2), PCNs, and TPCN-1, the H2 production activity of 0.1%G-TPCN under visible light is enhanced by 12.4, 2.3, and 1.4times, respectively, and its ciprofloxacin (CIP) degradation rate is increased by 7.9, 5.7, and 2.9 times, respectively. The optimized performance benefits from excellent photoresponsiveness and improved carrier separation and migration efficiencies. Finally, the photocatalytic mechanism of 0.1% G-TPCN and five possible degradation pathways of CIP are proposed. This study clarifies the mechanism of multiple modification strategies to synergistically improve the photocatalytic performance of 0.1% G-TPCN and provides a potential strategy for rationally designing novel photocatalysts for environmental remediation and solar energy conversion.

Naphthalene diimide-based cathode interlayer material enables 20.2% efficiency in organic photovoltaic cells

Science China Chemistry 2024年

作者： Yue Yu Jianqiu Wang Zhihao Chen Yang Xiao Zhen Fu Tao Zhang Haoyu yuan Xiao-Tao Hao l.ng ye Yong Cui Jianhui Hou State Key laboratory of Polymer Physics and Chemistry Beijing National Laboratory for Molecular Sciences Institute of Chemistry Chinese Academy of Sciences University of Chinese Academy of Sciences School of Physics State Key Laboratory of Crystal Materials Shandong University Beijing Advanced Innovation Center for Soft Matter Science and Engineering College of Materials Science and Engineering Beijing University of Chemical Technology School of Materials Science and Engineering Tianjin University

Cathode interlayer(CIl) materials play an important role in improving the power conversion efficiency(PCE) of organic photovoltaic(OPV) cells. However, the current understanding of the structure-property relationship in CIl materials is limited, and systematic studies in this regard are scarce. Here, two new CIl materials, NDI-PhC 4 and NDI-PhC 6 were synthesized by varying the alkylamine chain l.ngth on the NDI-Ph core. Our investigation reveals a systematic variation in the physical and chemical properties of these materials with increasing alkylamine chain l.ngth. Specifically, we observe a sequential decrease in melting point and self-doping effect, accompanied by an enhancement in crystallinity. Among these CIl materials, NDI-PhC 4 has a notable balance across various performance metrics. It also exhibits excellent surface modification capabilities, leading to a low surface roughness. Consequently, OPV cells based on NDI-PhC 4 achieve a PCE of 20.2%, which is one of the highest reported efficiencies for OPV cells. In addition, the appropriate melting point of NDI-PhC 4 contributes to the excellent stability of OPV cells.
