Synthesis and oxidation catalysis of a difluoride-incorporated polyoxovanadate and isolation of active vanadium alkylperoxo species

Abstract

Elucidation of the correlation between the catalytic performance and the structures of active sites on inorganic materials provides insights into the chemistry of the local structures on metal oxide catalysts....

Recent advances in oxidative catalytic applications of polyoxovanadate-based inorganic–organic hybrids

“…The free radicals of t -BuOO˙ and t -BuO˙ derived from the commonly used TBHP oxidant promoted by catalysts are considered to be the active species for oxidative transformation of alkenes; however, they are not in favor of improving the selectivity of products. 30 Therefore, the synthesis of efficient catalysts with high selectivity toward the oxidation of alkenes becomes an important topic.…”

Reactivity control of nitrate-incorporating octadecavanadates by changing the oxidation state and metal substitution

“…Local structure control among the related polyoxovanadates leads to understanding of the reactivity of the specific sites. 20 Nitrate-incorporating octadecavanadate [V 18 O 46 (NO 3 )] 5− (V18) possesses helicity. 21 The original procedure for synthesis of V18 involved the oxidation of dark purple decavanadate [V 10 O 26 ] 4− in nitromethane in the presence of nitrate.…”

Cation-controlled capture of polyoxovanadate-based organic–inorganic 1D architectures

“…5 In the realm of supramolecular chemistry, structure and function control in POMs has been achieved using internal (often anionic) templates, [6][7][8] as well as external structure-directing molecules. [9][10][11][12][13] Over the last decade, polyoxovanadate (POV) chemistry has undergone a tremendous developments; 3,14,15 while pioneering work in the late 20th century was dominated by structural and magnetic studies, 14,16,17 the field has now expanded to energy conversion and energy storage, 3,18,19 catalysis, 20,21 sensing, 22,23 spintronics 24,25 and solid-state reactivity models. 26,27 This is in part due to novel synthetic approaches which enable polyoxovanadate functionalization with metals, 28-30 semimetals 15,31 or organic moieties, 32,33 often working under non-aqueous conditions in organic solvents.…”
