Abstract

Facile ionothermal method has been employed to synthesize One-dimensional (1-D) mixed phase TiO2 nanorods (NRs) using ionic liquid as the reaction medium. The PXRD pattern reveals the formation of mixed phase TiO2 having 68.3% of anatase and 31.7% rutile phase with average crystallite size of ~ 10 nm. TEM images depict the average thickness of TiO2 NRs are in the range 50–100 nm. The 1-D mixed phase TiO2 NRs showed 5 times better hydrogen production activity than P-25 in the water-glycerol mixture under solar light irradiation. The reason could be the synergetic effect and unique optical properties of 1-D anatase–rutile TiO2 mixed-phase system.
