• of the material. The visible-light photocatalytic activity in the degradation of RhB surpasses that of the commercially available CeO2 and P25 TiO2 nanopowders. With a series of radical scavengers, the mechanism of the photocatalytic activity is proposed to involve a prominent role of •OH radicals as

• present work, we investigated a rapid and efficient one-step route for the direct IR-accelerated synthesis of LiNbO3 nanopowders using an ordered mesoporous silica SBA-15 as the template, in combination with an IR furnace for the crystallization. The matrix stabilizes the nanoparticles against sintering
