Lanthanide organic frameworks@TiO2 nanomaterials: luminescence and highly efficient photodegradation of phenol

Abstract

Over the past few years, the properties of upconverting nanomaterials have been investigated very intensively because of their potential applications in the fields of nanotechnology, nanomedicine, and photovoltaics. In particular, lanthanide-organic frameworks (LnOFs) have become current interests due to their unique luminescence properties, namely large ani-Stokes shift, sharp emission band, and long excited-state lifetime (Cui, Zhang, Chen, & Qian, 2016). These attributes are particularly needed for developing visible light-driven photocatalytic activity of titanium dioxide (TiO2) (Parnicka et al., 2017). Semiconductor-based heterogeneous photocatalysis is a promising technology for water purification without using consumables and generating harmful by-products.
