Multi-Angle Tracking Synthetic Kinetics of Phase Evolution in Li-Rich Mn-Based Cathodes Energy Environ. Sci. (IF 32.5) Pub Date : 2024-04-26 Shenyang Xu, Zhefeng Chen, Wenguang Zhao, Wenju Ren, Chenxin Hou, Jiajie Liu, Wu Wang, Chong Yin, Xinghua Tan, Xiaobing Lou, Xiangming Yao, Zhihai Gao, Hao Liu, Lu Wang, Zuwei Yin, Bao Qiu, Bingwen Hu, Tianyi Li, Cheng Dong, Feng Pan, Mingjian Zhang
As the commercial cathode with the highest practical capacity, the structural nature of Li-rich Mn-based cathodes (LMR), composite or solid solution, is still under debate. Due to the extreme structure similarity of two layered-phase components, monoclinic phase (C2/m) and rhombohedral phase (R-3m), no single tool can resolve this concern alone. Herein, we combined multiple advanced techniques to comprehensively

Mild and Catalytic Electrocyclizations of Heptatrienyl Anions. Chem. Sci. (IF 8.4) Pub Date : 2024-04-26 Arturo Orellana, Faizan Rasheed, Andrei Nikolaev, Anmol Dhesi, Tao Zeng, You Xuan Guo, Krishna Yarkali, Samira Komijani
We report a mild synthesis of functionalized cycloheptanes by thermal electrocyclization of heptatrienyl anions. In addition, we disclose the first examples of this electrocyclization manifold conducted under catalytic conditions. Previously, electrocyclization of heptatrienyl systems required formation of anions with strong base, resulting in limited functional group compatibility. We demonstrate

Multiconfigurational Actinide Nitrides Assisted by Double Möbius Aromaticity Chem. Sci. (IF 8.4) Pub Date : 2024-04-26 Xuhui Lin, Xiaoli Lu, Shenghui Tang, Wei Wu, Yirong Mo
Understanding the bonding nature between actinides and main-group elements remains a key challenge in actinide chemistry due to the involvement of f orbitals. Herein, we propose a unique “aromaticity-assisted multiconfiguration” (AAM) model to elucidate the bonding nature in actinide nitrides (An2N2, An= Ac, Th, Pa, U). Each planar four-membered An2N2 with equivalent An-N bonds possesses four delocalized

Promoting C−C Coupling for CO2 Reduction on Cu2O Electrocatalysts with Atomically Dispersed Rh Atoms Chem. Commun. (IF 4.9) Pub Date : 2024-04-26 Chengcheng Feng, Ruizhi Duan, Haibo Chi, Fengyuan Liu, Rui Song, Mingrun Li, Wen guang Yu, Chunmei Ding, Can Li
Cu2O doped with atomically dispersed Rh (Rh:Cu2O) is synthesized with a wet chemical method. It shows higher activity and Faradic efficiency at lower overpotential for CO2 reduction to C2+ products especially C2H4 than pristine Cu2O. We found that introducing Rh promotes CO2 adsorption, *CO hydrogenation to *CHO and their coupling to O*CCHO intermediates, which contributes to the enhanced catalytic
