Photothermal Conversion of W(18)O(49) with a Tunable Oxidation State

W(18)O(49) with a tunable oxidation state was prepared by addition of NaNO(3) or NaBH(4) as a redox agent in the solvothermal system. The addition of redox agents has no influence on the crystallization of W(18)O(49). The obtained W(18)O(49) structures keep their morphology as a bundle of nanowires...

description W(18)O(49) with a tunable oxidation state was prepared by addition of NaNO(3) or NaBH(4) as a redox agent in the solvothermal system. The addition of redox agents has no influence on the crystallization of W(18)O(49). The obtained W(18)O(49) structures keep their morphology as a bundle of nanowires with a regular hexagonal on the cross‐section. W(18)O(49) exhibits strong valence‐dependent absorption features in the near‐IR region. Reduced W(18)O(49) with more W(5+) has a higher concentration of oxygen vacancies, which enhances the localized surface plasmon resonance effect. Reduced W(18)O(49) exhibits a high photothermal conversion efficiency of 59.6 % and has good photothermal stability.
