Nanomaterials made of titanium dioxide (TiO2) are commonly regarded as state-of-the-art photocatalysts for environmental remediation and energy conversion. Due of its unique electrical and optical characteristics, several attempts have been made to manufacture TiO2 materials using various techniques. The electrical and optical characteristics of TiO2 materials have long been investigated. The development of oxygen vacancies and Ti3+ defects in black TiO2 has increased solar light absorption, promoted the separation of photo-generated charge carriers, and therefore improved photocatalytic activity in H2 generation and pollutant degradation. A lattice disorder on the surface, as well as the presence of oxygen vacancies, Ti3+ ions, Ti-OH, and Ti-H groups, contribute to black TiO2's improved photocatalytic activity. Enhancing the optical absorption characteristics of TiO2.In this article, we summarize the synthesis pathways, morphology and photocatalytic properties of Black titanium dioxide (TiO2).

Keywords : Synthesis pathways, Morphology, Photocatalysis.
