This work presents an electrocatalyst, Ru cluster with Mo doping, which shows competitive alkaline HER performance with ultra-low Ru content, revealing the modulation of heteroatom doping for alleviating OH∗ poisoning.

2. Revealing the reason for the unsuccessful fabrication of Li₃Zr₂Si₂PO₁₂ by solid state reaction

Zizhuo Liang, Fuming Du, Ning Zhao*, Xiangxin Guo*. Chin. J. Struct. Chem., 2023, 42, 100108

https://doi.org/10.1016/j.cjsc.2023.100108

The experimental results combined with thermodynamic analysis revealed that the formation of Li₃PO₄·2ZrSiO₄ takes precedence over forming Li₃Zr₂Si₂PO₁₂, due to the relatively low Gibbs-free-energy of the reaction between ZrO₂ and SiO₂ catalyzed by Li₃PO₄. This study indicates that developing methods with mild conditions is crucial for the Li₃Zr₂Si₂PO₁₂ preparation.

3. Metal-organic framework derived MnO@C/CNTs composite for high-rate lithium-based semi-solid flow batteries

Benjian Xin, Rui Wang, Lili Liu*, Zhiqiang Niu. Chin. J. Struct. Chem., 2023, 42, 100116

https://doi.org/10.1016/j.cjsc.2023.100116

MnO@C/CNTs composite was applied as electrode slurry of lithium-based semi-solid flow battery. The MnO@C/CNTs structure increases the suspension of materials and ensures the long-term stability of the slurry, resulting in high-rate performance and long cycling life of lithium-based semi-solid flow battery.

4. Depositing the PtNi nanoparticles on niobium oxide to enhance the activity and CO-tolerance for alkaline methanol electrooxidation

Xinyi Hu, Riguang Zhang*, Zhao Jiang*. Chin. J. Struct. Chem., 2023, 42, 100157

The related reaction scheme to clarify the novelty of this work: In this work, the PtNi/Nb₂O₅–C bimetallic catalysts are synthesized by the ethylene glycol solvothermal method, which exhibit the evidently increased catalytic performance for alkaline MOR. The electronic effect and the hydroxyl brought from Ni species are mainly ascribed for the enhancement of activity and CO tolerance.

5. Core-shell gold-copper nanoparticles: Evolution of copper shells on gold cores at different gold/copper precursor ratios

Shaonan Tian, Yu Zhang, Qing Zeng, Junyu Zhong, Hui Liu*, Lin Xu*, Jun Yang*. Chin. J. Struct. Chem., 2023, 42, 100160

https://doi.org/10.1016/j.cjsc.2023.100160

The intriguing evolution of copper (Cu) shells on the gold (Au) cores at different Au/Cu precursor ratios during the synthesis of core-shell Au–Cu nanoparticles at an organic medium via seed-mediated growth method is reported in this paper.

Renshu Huang, Jinli Chen, Xingfa Chen, Tianqi Yu, Huyi Yu, Kaien Li, Bin Li*, Shibin Yin*. Chin. J. Struct. Chem., 2023, 42, 100171

https://doi.org/10.1016/j.cjsc.2023.100171

The formation and decomposition of the discharge product Li₂O₂ are accelerated by 3D porous Mn₂O₃@CeO₂ heterojunction with oxygen vacancies.

7. Fluorinated metal-organic framework for methane purification from a ternary CH₄/C₂H₆/C₃H₈ mixture

Ke-Ai Zhou, Lian Huang, Xing-Ping Fu, Li-Ling Zhang, Yu-Ling Wang, Qing-Yan Liu*. Chin. J. Struct. Chem., 2023, 42, 100172

https://doi.org/10.1016/j.cjsc.2023.100172

A fluorinated metal-organic framework with polarized micropore environments exhibiting excellent methane purification ability is presented.

8. Pd-based nanocatalysts for oxygen reduction reaction: Preparation, performance, and in-situ characterization

Guan-Nan Xing, Di-Ye Wei, Hua Zhang, Zhong-Qun Tian*, Jian-Feng Li*. Chin. J. Struct. Chem., 2023, 42, 100021

https://doi.org/10.1016/j.cjsc.2023.100021

This paper reviews the research progress of preparation, electrocatalytic performance, and in-situ characterization of various Pd-based oxygen reduction catalysts from 0-dimensional nanoparticles, to one-dimensional nanowires, to two-dimensional nanosheets and to Pd single-atom catalysts. It may provide some help for improving the activity of Pd-based catalysts and understanding the reaction mechanisms and structure-activity relationships.
