Growth of the nanowires by Joule heating is a rapid process, with times of treatment in the range of seconds or minutes, whereas times for more conventional and widespread VS growth are normally in the range of hours at an elevated temperature. Nanowires grown by the two techniques are shown to have similar morphologies and to be single crystalline. The incorporation of Tb dopants into both kinds of nanowires was investigated by using energy-dispersive X-ray spectroscopy and electron energy-loss spectroscopy. In nanowires grown by the VS method, Tb was found to aggregate and form Tb oxide nanoparticles on parts of the nanowire surfaces. In nanowires grown by Joule heating, no segregation of the dopants was observed.

Reducing the energy barrier of these reactions accentuates the necessity in designing competent electrocatalysts. There is an urgent demand for affordable and durable catalysts utilizing non-noble metals, specifically Ni, Co, and Fe, for the OER. In this context, three following cobalt(II) coordination frameworks based on a pyridyl carboxylic acid ligand were synthesized: [Co<sub>3</sub>(μ<sub>3</sub>-OH)(PCA)<sub>4</sub>(DMF)<sub>2</sub>(H<sub>2</sub>O)](NO<sub>3</sub>)·DMF·3H<sub>2</sub>O (<b>1</b>), [Co<sub>3</sub>(μ<sub>3</sub>-OH)(PCA)<sub>4</sub>(EtOH)<sub>3</sub>](NO<sub>3</sub>)·3EtOH·3H<sub>2</sub>O (<b>2</b>), and [Co<sub>3</sub>(μ<sub>3</sub>-OH)(PCA)<sub>4</sub>(DMA)<sub>2</sub>(H<sub>2</sub>O)] (ClO<sub>4</sub>)·DMA·H<sub>2</sub>O) (<b>3</b>) using a solvothermal method.

Compound <b>1</b> shows extraordinary OER activity demonstrating an overpotential value of 0.37 V at 10 mA cm<sup>–2</sup> and a Tafel slope of 78.9 mV. The alternation in the coordination sphere resulting from the difference in coordinated solvent emerges as an intriguing reason contributing to the exceptional activity of a coordination network. The effective electronic modulation within the cobalt trinuclear center induced by the changes in the coordination sphere has lowered the free energy barrier for the desorption of the oxygen produced.

Meanwhile, due to their nontoxic nature and cost-effective manufacturing, the huge potential of various tin–sulfur-based materials has been explored for LIB applications. On account of the superior advantage of organic- and Sn–S-based electrodes, a tetranuclear organotin sulfide cage, [(RSn<sup>IV</sup>)<sub>4</sub>(μ-S)<sub>6</sub>], <b>2</b>, was designed from a newly synthesized monoorgano tin precursor RSnCl<sub>3</sub>, <b>1</b>, where R = (2,4-dimethylpentylidene)hydrazinylpyridine. The molecular structures of these compounds are characterized by single-crystal X-ray diffraction (SCXRD) and various other spectroscopic techniques. In this work, compound <b>2</b> was exclusively examined as an anode material for LIBs. The designed electrode has shown interesting rate-dependent specific capacities. A specific discharge capacity of 135.6 mAh g<sup>–1</sup> was observed at a current density of 75 mA g<sup>–1</sup> with 75% capacity retention after 100 cycles. Two different types of rate-dependent lithiation mechanisms have been identified. It was found that at a higher rate (0.4 C), the molecule can accommodate 8 Li<sup>+</sup> ions showing a specific capacity of 126 mAh g<sup>–1</sup>, whereas at a slower rate (C/30), the molecule can accommodate 16 Li<sup>+</sup> ions delivering a specific capacity of 232 mAh g<sup>–1</sup>.</p>","PeriodicalId":34,"journal":{"name":"Crystal Growth & Design","volume":"24 23","pages":"9857–9866 9857–9866"},"PeriodicalIF":3.2,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142761075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
