Synthesis of Rutile Nb:TiO₂ Free‐Standing Thin Film at the Liquid–Air Interface

One-step hydrothermal synthesis of the niobium doped rutile TiO2 free standing film at the liquid–air interface without the use of a template is presented. Film is flexible within first few minutes of removal from the solution and allows application on various shaped objects and substrates.
