Employing a new 12-connected topological open-framework copper borovanadate as an effective heterogeneous catalyst for oxidation of benzyl-alkanes†
Abstract
A new 12-connected topological open-framework copper borovanadate NNU-6 with a unique B/V ratio (20/12) and a –B3O7(OH)–Na(μ-OH)[B(OH)2]–B3O7(OH)– connection mode has been hydrothermally obtained and characterized. It not only features the first 3-D copper(II) borovanadate which possesses the largest ratio of TM2+ and borovanadate anion, but also displays highly catalytic activities for the oxidation of benzyl-alkanes.
