Conjugated Polymer Modifying TiO Performance for Visible-Light Photodegradation of Organics.

Up to now, the use of TiO has been considered a promising advanced technology for organic pollutants removal from air or water, since it has high biological and chemical stability, high photoactivity, low toxicity, and low-cost production. However, there are issues to be addressed in enhancing TiO performance, and one of the current key issues is redesigning UV-active photocatalysts and making them active in the visible region of the electromagnetic spectrum. This way, solar light absorption will be insured, and thus, a more efficient photocatalyst could be obtained.

Sequential Synthesis Methodology Yielding Well-Defined Porous SrTiO/NiFeO Nanocomposite.

In this research, we reported on the formation of highly porous foam SrTiO/NiFeO (STO/NFO) heterostructure by joint solid-state and sol-gel auto-combustion techniques. The colloidal assembly process is discussed based on the weight ratio x (x = 0, 25, 50, 75, and 100 wt %) of NiFeO in the STO/NFO system. We proposed a mechanism describing the highly porous framework formation involving the self-assembly of SrTiO due to the gelation process of the nickel ferrite.
