One-step Synthesis of Black TiO2 Composite Coating on Glass by Pulsed Laser Spraying
To achieve effective load of black TiO2 nanoparticles and improve the practical application ability, the pulsed laser spraying was proposed. The composite coating was prepared on quartz glass substrate, which consisted of amorphous molecular sieve and rutile TiO2 nanocrystals. The surface morphology of the composite coating was characterized, and a series of test about composite coating powder was conducted including absorption properties, phase structure, chemical valence, and photocatalytic properties. The results show that the coating is porous structure packed with 2-5 μm ball and has strong absorptive capacity in the visible region. In the process of pulsed laser sputtering, the molecular sieve changed to amorphous structure, and TiO2 changed from anatase to rutile type. Ti4+ ion was reduced to Ti3+ ion, which resulted in reduced band-gap. The pulsed laser spraying technology achieves the fast load of the black nano TiO2, which still has good photocatalytic ability under the full spectrum and visible light conditions.
