Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), name: Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II).
Cerium-based materials such as ceria are increasingly used in catalytic reactions. We report here the synthesis of the first Ce-based metal-organic layer (MOL), Ce6-BTB, comprising Ce6 secondary building units (SBUs) and 1,3,5-benzenetribenzoate (BTB) linkers, and its functionalization for photocatalytic hydrogen evolution reaction (HER). Ce6-BTB was postsynthetically modified with photosensitizing [(MBA)Ir(ppy)2]Cl or [(MBA)Ru(bpy)2]Cl2 (MBA = 2-(5?-methyl-[2,2?-bipyridin]-5-yl)acetate, ppy = 2-phenylpyridine, bpy = 2,2?-bipyridine) to afford Ce6-BTB-Ir or Ce6-BTB-Ru MOLs, respectively. The proximity of photosensitizing ligands and Ce6 SBUs in the MOLs facilitates electron transfer to drive photocatalytic HER under visible light with turnover numbers of 1357 and 484 for Ce6-BTB-Ir and Ce6-BTB-Ru, respectively. Photophysical and electrochemical studies revealed a novel dual photoexcitation pathway whereby the excited photosensitizers in the MOL are reductively quenched and then transfer electrons to Ce6 SBUs to generate CeIII centers, which are further photoexcited to CeIII? species for HER.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.name: Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II). In my other articles, you can also check out more blogs about 15746-57-3
