The field emission (FE) properties of TiO2 nanotube arrays (TNAs) synthesized by anodization are dramatically improved after hydrogenation at various temperatures in a range 400–550 °C. Compared with pristine TNAs, the turn-on fields hydrogenated TNAs (H:TNAs) significantly decreased from 18.23 to 1.75 V μm−1, and closely related temperature. Importantly, optimized sample H:TNAs prepared 550 °C shows excellent FE performances involving both low high current density 4.0 mA cm−2 4.50V...
