Low-temperature route to metal titanate perovskite nanoparticles for photocatalytic applications
Abstract
<p>MTiO<sub>3</sub> (M=Ca, Sr, Ba) nanoparticles were synthesized by a one-step room-temperature ultrasound synthesis in ionic liquid. The obtained samples are characterized by X-ray diffraction, scanning electron microscopy, nitrogen adsorption, UV-vis diffuse reflectance, Raman and IR spectroscopy and their capability in photocatalytic hydrogen evolution and methylene blue degradation was tested. Powder X-ray diffraction and Raman spectroscopic investigations revealed the products to crystallize in the cubic perovskite structure. SEM observations showed that the obtained CaTiO<sub>3</sub> consists of nanospheres, BaTiO<sub>3</sub> of raspberry-like shaped particles of 20nm in diameter. SrTiO<sub>3</sub> particles have cubic-like morphology with an edge length varying from 100 to 300nm. SrTiO<sub>3</sub> exhibited the highest catalytic activity for photocatalytic H<sub>2</sub> evolution using only 0.025wt.% Rh as co-catalyst and for the degradation of methylene blue under UV irradiation. The influence of parameters such as synthesis method, calcination temperature, and doping with nitrogen on the morphology, crystallinity, chemical composition, and photocatalytic acivity of SrTiO<sub>3</sub> was studied. Heating the as-prepared SrTiO<sub>3</sub> to 700°C for extended time leads to a decrease in surface area and catalytic activity. Ionothermal prepared SrTiO<sub>3</sub> exhibits a higher activity than sonochemically prepared one without co-catalyst due to a synergistic effect of anatase which is present in small amount as a by-phase. After photodeposition of Rh, however, the activity is lower than that of the sonochemically prepared SrTiO<sub>3</sub>. Nitrogen-doped SrTiO<sub>3</sub> showed photocatalytic acivity under visible light irradiation.</p>
