Keggin-type polyoxometalate nanosheets: synthesis and characterization via scanning transmission electron microscopy†
Abstract
Polyoxometalate nanosheets were synthesized at the gas/liquid interface of an aqueous solution of Keggin-type silicotungstic acid, cesium chloride, and n-octylamine. The structure of the nanosheets was elucidated via aberration-corrected scanning transmission electron microscopy at the atomic and molecular levels.
