Open vacancies : A facile one‐pot synthesis of oxygen‐vacancy‐rich ultrathin W 18 O 49 nanowires up to several micrometers long is described. In addition to unique optical properties, such as NIR absorption and blue‐light emission, the nanowires show an unexpected ability to photochemically reduce carbon dioxide to methane (see picture) as a result of its defect structure caused by large quantities of oxygen vacancies.
