A facile non‐hydrogenated method for fabrication of black TiO2‐x/bacterial cellulose composites with improved photocatalytic performance

Abstract

Abstract Black titanium dioxide (TiO2‐x) has attracted extensive attention owing to its visible light absorption and superior photodegradation activity. Here, black TiO2‐x nanocomposites are fabricated via a two‐step method followed by a heat treatment process under an argon atmosphere, and then the black TiO2‐x is loaded onto the bacterial cellulose surface by surface grafting. The presence of Ti3+ species and oxygen vacancies is proved by XPS characterisation. Furthermore, the black TiO2‐x exhibits excellent photocatalytic activity for pollutants degradation.
