Abstract

We report on a novel route of preparing molybdena-modified bismuth tungstates and their successful application in the photocatalytic oxygen evolution reaction and the oxidation of glycerol. Hierarchically assembled monocrystalline Bi₂WO₆ nanoplatelets with a specific surface area of 10 m²/g were obtained applying a hydrothermal synthesis method using Na₂WO₄ and Bi(NO₃)₃ as precursors, followed by a solvent-free chemical vapor deposition method using Mo(CO)₆, resulting in highly dispersed molybdena species. Extensive characterization using X-ray photoelectron spectroscopy, low-energy ion scattering, and Raman spectroscopy showed that microcrystalline MoO₃ islands were formed on the bismuth tungstate surface that grew in height and lateral dimension with increasing loading. Correspondingly, the molybdena-modified materials were found to have favorable photocatalytic and photoelectrochemical properties in the oxygen evolution reaction and the selective oxidation of glycerol.
