Unlocking bimetallic active sites via a desalination strategy for photocatalytic reduction of atmospheric carbon dioxide

Nature Communications (2022)

Xuezhen Feng Renji Zheng Cai‐Yan Gao Wenfei Wei Jiangguli Peng

Ultrathin two-dimensional (2D) metal oxyhalides exhibit outstanding photocatalytic properties with unique electronic and interfacial structures. Compared with monometallic oxyhalides, bimetallic oxyhalides are less explored. In this work, we have developed a novel top-down wet-chemistry desalination approach to remove the alkali-halide salt layer within the complicated precursor bulk structural matrix Pb0.6Bi1.4Cs0.6O2Cl2, and successfully fabricate a new 2D ultrathin bimetallic oxyhalide Pb0.6Bi1.4O2Cl1.4. The unlocked larger surface area, rich bimetallic active sites, and faster carrier dynamics within Pb0.6Bi1.4O2Cl1.4 layers significantly enhance the photocatalytic efficiency for atmospheric CO2 reduction. It outperforms the corresponding parental matrix phase and other state-of-the-art bismuth-based monometallic oxyhalides photocatalysts. This work reports a top-down desalination strategy to engineering ultrathin bimetallic 2D material for photocatalytic atmospheric CO2 reduction, which sheds light on further constructing other ultrathin 2D catalysts for environmental and energy applications from similar complicate structure matrixes.

From 1D to 3D: Fabrication of CH₃NH₃PbI₃ Perovskite Solar Cell Thin Films from (Pyrrolidinium)PbI₃ via Organic Cation Exchange Approach

Energy Technology (2020)

Miao Yu Haochen Fan Pengcheng Wang Yue Zhang Cai‐Yan Gao

A new crystal form of 1D perovskite (pyrrolidinium)PbI 3 (orthorhombic phase) is synthesized and characterized. The 1D perovskite has a good film formability by solution spin coating and is in situ transformed to 3D CH 3 NH 3 PbI 3 via the organic cation exchange approach in CH 3 NH 2 atmosphere, which is dense and uniform. The converted 3D perovskite film is used as a light absorber, and the corresponding perovskite solar cell shows a power conversion efficiency of up to 19.2% under simulated 1 sun AM1.5G illumination (100 mW cm −2 ).

Fine‐Tuning Active Layer Morphology via Modification of Both Side Chains and Terminal Groups toward High‐Performance Organic Solar Cells

Energy Technology (2021)

Jinfeng Huang Cai‐Yan Gao Xin‐Heng Fan Xiaozhang Zhu L. Yang

Both the structures and the phase properties of electron acceptors with nonfused aromatic cores (NCAs) have received intensive investigation in very recent years, nevertheless, there remains a large space for manipulating their phase properties through synergistically tuning the side chains and end groups of the NCAs. Herein, four unfused acceptors based on quinoxaline‐core, namely QOD‐4H, QOD‐2Cl, QOS‐4H, and QOS‐2Cl, are designed and synthesized by simple steps, and multiple characterizations are conducted to further explore their blend morphology properties and stacking orientations. Particularly, the alkyl side chains in QOS‐4H and QOS‐2Cl with lower steric hindrance slightly decrease the crystallinity, optical absorption, and tendency toward the face‐on orientation but distinctly cause shorter π–π stacking distance. Meanwhile, two chlorine atoms introduced to the end caps of QOD‐2Cl and QOS‐2Cl produce weaker crystallinity, but with more compact molecular packing, stronger face‐on orientation, and distinctly larger extinction coefficients. As a combinative result, the better nanofibrillar networks and closer molecular stacking are detected in QOD‐2Cl‐ and QOS‐2Cl‐based blends, which lead to a higher efficiency of 10.67% and 12.19%, respectively, of the related devices than those from acceptors QOD‐4H (6.94%) and QOS‐4H (8.01%).
