Primary Model

In this work, an upconversion luminescence agent, crystallized Er3 + :YAlO3, was synthesized and then coated by the nano-sized TiO2 film through sol–gel technique. A novel TiO2 photocatalyst, Er3 + :YAlO3/TiO2, with high activity in visible light was subsequently prepared. The Er3 + :YAlO3 and Er3 + :YAlO3/TiO2 were characterized by X-ray diffraction (XRD) and transmission electron microscope (TEM). The photocatalytic activity of Er3 + :YAlO3/TiO2 photocatalyst was tested by the degradation of acid red B in aqueous solution as the primary model compound under visible light irradiation. The experimental results proved that the prepared TiO2-coated crystallized Er3 + :YAlO3 was able to decompose the acid red B efficiently, and it is promising to use the idea to develop new TiO2 photocatalyst with high activity for photocatalytic degradation under visible light.

Different Types

In the past several years, solar-driven photocatalytic degradation of organic dyes has been considered as one of the most promising and effective ways to address water pollution issues. Nevertheless, the implementation of such technology for large scale industrial wastewater application is still hampered by the limitation in currently used photocatalysts. Recently, plasmon-enhanced titania-based nanocatalyst has emerged as one of the promising photocatalytic materials for solar-driven wastewater treatment due to its excellent activity and ability to absorb a large portion of solar radiation. Therefore, this review highlights recent progress on applying such material for the photodegradation of organic dyes. In this review, the focus is placed on several mechanisms on how the surface plasmon resonance (SPR) phenomenon could enhance the photocatalytic activity of semiconductors, such as TiO2. Furthermore, the performance of several types of plasmon-enhanced titania nanocatalyst with different kinds of metal plasmonic nanoparticles, i.e., Au-TiO2, Ag-TiO2, and Pd-TiO2, is also compared and comprehensively discussed. Finally, a particular emphasis is also given to highlight the nanocatalysts' kinetics in facilitating the photocatalytic degradation of different types of organic dyes.
