Low-temperature synthesis of mesoporous ZnTiO₃–graphene composite for the removal of norfloxacin in aqueous solution

Abstract

A novel mesoporous perovskite-type ZnTiO3–graphene (MZT–GR) material was successfully fabricated via a two-step process in this paper.

Conscientious Design of Zn-S/Ti-N Layer by Transformation of ZnTiO3 on Electrospun ZnTiO3@TiO2 Nanofibers: Stability and Reusable Photocatalytic Performance under Visible Irradiation

“…In this context, TiO 2 and ZnO are the most promising semiconductor photocatalysts with their wide band gap function facilitating their exploration for wastewater treatment. However, both these semiconductors have their individual advantages and disadvantages when it comes to their catalytic efficiency under UV irradiation owing to the favorable wide band gap (>3.2 eV). , Alloying these wide band gap materials in the form of ternary oxides such as ZnTiO 3 favors a similar band function, overcoming their structural disadvantages. , It is a known fact that UV photon energy accounts only for nearly 5% of total solar energy, which is very low when compared to 45% of visible photon energy . In order to commercialize advanced oxidation process based wastewater treatments, solar energy has to be utilized, and semiconductor nanostructures have to be developed in such a way that they effectively drive visible catalytic behavior .…”
