Precise design and tuning of the micro-atomic structure of single atom catalysts (SACs) can help efficiently adapt complex catalytic systems. Herein, we inventively found that when the active center of the main group element gallium (Ga) is downsized to the atomic level, whose characteristic has significant differences from conventional bulk and rigid Ga catalysts. The Ga SACs with a P, S atomic coordination environment display specific flow properties, showing CO products with FE of ≈92 % at −0.3 V vs. RHE in electrochemical CO 2 reduction (CO 2 RR). Theoretical simulations demonstrate that the adaptive dynamic transition of Ga optimizes the adsorption energy of the *COOH intermediate and renews the active sites in time, leading to excellent CO 2 RR selectivity and stability. This liquid single atom catalysts system with dynamic interfaces lays the foundation for future exploration of synthesis and catalysis.

Boron-Induced Interstitial Effects Drive Water Oxidation on Ordered Ir−B Compounds

Interstitial filling of light atoms strongly affects the electronic structure and adsorption properties of the parent catalyst due to ligand and ensemble effects. Different from the conventional doping and surface modification, constructing ordered intermetallic structures is more promising to overcome the dissolution and reconstruction of active sites through strong interactions generated by atomic periodic arrangement, achieving joint improvement in catalytic activity and stability. However, for tightly arranged metal lattices, such as iridium (Ir), obtaining ordered filling atoms and further unveiling their interstitial effects are still limited by highly activated processes. Herein, we report a high-temperature molten salt assisted strategy to form the intermetallic Ir−B compounds (IrB 1.1 ) with ordered filling by light boron (B) atoms. The B residing in the interstitial lattice of Ir constitutes favorable adsorption surfaces through a donor-acceptor architecture, which has an optimal free energy uphill in rate-determining step (RDS) of oxygen evolution reaction (OER), resulting in enhanced activity. Meanwhile, the strong coupling of Ir−B structural units suppresses the demetallation and reconstruction behavior of Ir, ensuring catalytic stability. Such B-induced interstitial effects endow IrB 1.1 with higher OER performance than commercial IrO 2 , which is further validated in proton exchange membrane water electrolyzers (PEMWEs).

Thin Zinc Electrodes Stabilized with Organobromine-Partnered H2O−Zn−MeOH Cluster Ions for Practical Zinc-Metal Pouch Cells

Angewandte Chemie 2024年第2期137卷

作者： Jie Ji Haoran Du Zhenglu Zhu Xiaoqun Qi Fei Zhou Rui Li Ruining Jiang Prof. Long Qie Yunhui Huang State Key Laboratory of Material Processing and Die & Mold Technology School of Materials Science and Engineering Huazhong University of Science and Technology Wuhan Hubei 430074 Key Laboratory of Materials and Technologies for Advanced Batteries School of Energy Materials and Chemical Engineering Hefei University Hefei Anhui 230601 China

The utilization of thin zinc (Zn) anodes with a high depth of discharge is an effective strategy to increase the energy density of aqueous Zn metal batteries (ZMBs), but challenged by the poor reversibility of Zn electrode due to the serious Zn-consuming side reactions at the Zn||electrolyte interface. Here, we introduce 2-bromomethyl-1,3-dioxolane (BDOL) and methanol (MeOH) as electrolyte additive into aqueous ZnSO 4 electrolyte. In the as-formulated electrolyte, BDOL with a strong electron-withdrawing group (−CH 2 Br) tends to pair with the H 2 O−Zn−MeOH complex, leading to the formation of organobromine-partnered H 2 O−Zn−MeOH cluster ions. During the Zn electrodeposition process, the formed ZnO-dominated by-products induce the polymerization of BDOL monomers, which are previously adsorbed on the electrode. As a result, a uniform dual-layer SEI with ZnO-dominated outer layer and polyether-dominated inner layer is built on the surface of Zn electrode. With such an in situ formed dual-layer SEI, the Zn||Mg 0.9 Mn 3 O 7 ⋅ 2.7H 2 O pouch cell using a 10-um Zn anode (corresponding to a low negative to positive areal capacity ratio of 3.56) successfully operated for 300 cycles with a high capacity retention of 86 %, promising a high practical energy density of >120 Wh/kg (based on the total mass of Zn and Mg 0.9 Mn 3 O 7 ⋅ 2.7H 2 O).

Smart Polymers with Special Wettability

Small (Weinheim an der Bergstrasse, Germany) 2017年第4期13卷 2017 Jan;13(4)页

Surface wettability plays a key role in addressing issues ranging from basic life activities to our daily life, and thus being able to control it is an attractive goal. Learning from nature, both of its structure and function, brings us much inspiration in designing smart polymers to tackle this major challenge. Life functions particularly depend on biomolecular recognition-induced interfacial properties from the aqueous phase onto either "soft" cell and tissue or "hard" inorganic bone and tooth surfaces. The driving force is noncovalent weak interactions rather than strong covalent combinations. An overview is provided of the weak interactions that perform vital actions in mediating biological processes, which serve as a basis for elaborating multi-component polymers with special wettabilities. The role of smart polymers from molecular recognitions to macroscopic properties are highlighted. The rationale is that highly selective weak interactions are capable of creating a dynamic synergetic communication in the building components of polymers. Biomolecules could selectively induce conformational transitions of polymer chains, and then drive a switching of physicochemical properties, e.g., roughness, stiffness and compositions, which are an integrated embodiment of macroscopic surface wettabilities.

A C156 Molecular Nanocarbon: Planar/Rippled Nanosheets Hybridization

引用

Angewandte Chemie 2024年第6期137卷

作者： Ruihua Fu Xingyu Chen Fei Qiu Xinyue Liu Prof. Jianlong Xia Prof. Lei Zhang Beijing Advanced Innovation Center for Soft Matter Science and Engineering State Key Lab of Organic-Inorganic Composites Beijing University of Chemical Technology 100029 Beijing P. R. China State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Center of Smart Materials and Devices Wuhan University of Technology 430070 Wuhan P. R. China

A novel hybrid nanocarbon consisting of one rippled and two planar nanosheets has been synthesized and characterized. Two meso pairs of [5]helicenes are formed along the long molecular axis of the hybrid to connect rippled and planar subunits, leading to a stable conformation. It is shown that the hybrid possesses the individual electronic properties of the rippled and planar subunits. Compared to the rippled subunit, such hybrid has a better geometric match to C 60 and complexes with C 60 in a 1 : 1 stoichiometry, with the association constant on the order of 10 5 M −1 . The hybrid displays unusual anti -Kasha fluorescence emission. The transient absorption spectroscopy revealed that the singlet fission (SF) from higher level singlet excited states (S n ) is operative in the film of the hybrid.
