Enhancement of the visible light absorption intensity of microporous vanadosilicate AM-6

Abstract

AM-6 with high intensity visible light absorption at 400–800 nm was synthesized via a hydrothermal route in the presence of F⁻ ions. Structure characterization and DFT calculations indicate that the unusual optical properties originate from the connection of octahedral VO₆ wires with distorted tetrahedral VO₄ units, which are stabilized in the framework of AM-6.
