Films of rutile titania nanoparticles with nearly spherical morphology were prepared using chemical solution deposition at room temperature. The results of the study show that the phase, size and morphology of the particle and the compactness of the film can apparently be controlled by controlling the surface hydrogenation of the particle. The results were very much in agreement with the predictions made by the established thermodynamic model of Barnard and Zapol. The present study opens new avenues for the synthesis of phase specific nanoparticles of titania with different morphologies at room temperature by varying the levels of surface hydrogenation.
